The technology of growing radishes in a greenhouse in spring and winter - instructions for beginners. When to plant radishes in a greenhouse for an early, bountiful harvest

Radish is a juicy and very healthy root vegetable that gives dishes a special, piquant taste. It is rich in micro and macro elements, fatty acids, glycosides, and is also easy and unpretentious in care. Therefore, growing radishes in a greenhouse can be done even by a novice gardener, the main thing is to choose the right variety and growing method.

It is really not necessary to have high agronomic knowledge to grow radishes. It is enough to pay attention to the biology of this root crop, its physiological and ecological features.

Radish is an annual photophilous plant from the cabbage class. As you know, almost all cabbage plants are heat-loving plants. Therefore, to form a full-fledged crop, he simply needs a sufficient amount of heat and light. It is interesting that, despite the thermophilicity, radish perfectly withstands temperatures down to -3 degrees Celsius.

For proper care it is important to monitor the radish so that the temperature is still in the range of eighteen to twenty degrees Celsius, otherwise various anomalies may develop.

Growing radishes in a greenhouse requires attention to the soil on which the vegetable grows. Currently, there are even selective soils to inhibit the development of fungal or bacterial pathogens. If you do not have the opportunity to purchase such soil, just remember: radishes grown on acidic soil can become infected with clubroot. The growth of radishes in a greenhouse with potassium deficiency is complicated, it is extremely slow, almost no root crops are formed. The same thing happens with nitrogen deficiency.

In general, with the right selection of care products, this vegetable can grow in the month of February, despite frosts. Under such conditions, radish grows best and bears fruit in a polycarbonate greenhouse.

In order for the radish to grow quickly and give a good harvest, it is necessary to properly care for the seedlings. For a quality crop Special attention should be directed to the ground. It should not be forgotten that, unlike natural soil, many biological and physical processes will be absent in an enclosed space that will have to be compensated. Growing radishes in a greenhouse requires a soil that is neutral in composition. For leaching acidic soil recommend adding horse dung at the rate of one and a half buckets per square meter of land.

In order to avoid harmful microorganisms, before laying in greenhouses, the soil must be sterilized - this is done under the influence high temperature or pressure. In rare cases, you can resort to an autoclave. But still, the most popular method is either the fumigation of the soil and the premises with compounds of substances toxic to pests, or the roasting of the soil.

Be sure to add fertilizer. It is noted that the weak link in the mineral nutrition of radish is phosphorus and potassium. In order to avoid crop loss, superphosphate is added at the rate of forty grams per square meter of soil, as well as potassium chloride - fifteen grams per square meter. The addition of these fertilizers will improve the growth and productivity of root crops. Do not forget about controlling the amount of nitrogen and potassium, without which the normal formation of the crop is impossible.

Preparing seeds for planting

Choice the right material- the lion's share of success in the agricultural business. For planting, it is best to use large (up to three and a half millimeters in length) seeds. At home, it is not difficult to select seeds - pass the seeds through a sieve with large cells.

There are separately bred varieties of radish seeds for planting in greenhouses. This is due to the fact that growing radishes in a greenhouse has its own physiological characteristics that can play into the hands of gardeners.

Right before planting the seeds in the ground, they must be left in the water for several days, maintaining room temperature. This is best done in a thermostat on layers of gauze. After this procedure, it is recommended to treat the seeds with a solution of fungicides, or a weak dilution of potassium permanganate. After that, the dried seeds are planted in the ground.

disembarkation

It is best to plant radishes in a polycarbonate greenhouse. Usually, the entire landing procedure is done manually. The distance between seeds usually varies from one to two centimeters, between rows - from six to eight centimeters. Do not immerse the seeds too deep in the kidney - it is more than enough to lower it one centimeter. Before planting, it is recommended to carry out a drip irrigation system.

Compliance with at least these minimum requirements will exhaustively answer the question: how to grow radishes in a greenhouse.

seedling care

In general, it is necessary to control several parameters - air temperature, illumination, humidity, pest contamination and mineral nutrition seedlings.

Thanks to the subtleties of greenhouse maintenance, we can change the temperature during the entire growing season of the plant. During seed germination, the temperature should be low from two to four degrees to sixteen. After the seedlings began to sprout en masse, the temperature is slightly lowered, to six degrees. After four days in this mode, the temperature is again raised to the original values.

Of course, there are difficulties if your greenhouse is unheated. In this case, it is possible to lower the temperature mechanically without resorting to heating system. An unheated greenhouse can be compensated by the use of special materials in its manufacture. So, a radish that grows in a polycarbonate greenhouse does not feel critical temperature fluctuations, and generally gives a rich harvest.

How much should seedlings be watered? This question is asked by many gardeners. With a lack of moisture, the roots come out dry and insipid, with an overabundance of moisture, plants can suffer from root rot or a black leg of seedlings.

Therefore, the watering of the radishes that you grow in the greenhouse must be compensated. Do not let the soil dry out completely. It is best to supply water from below, to a depth of ten to fifteen centimeters.

The nuances of early planting radishes

Early planting radishes in the greenhouse, we are faced with certain difficulties. In greenhouses that are not heated, or they are made of poorly heat-retaining materials, they stand without a foundation until the soil warms up, otherwise you risk losing the entire crop. Seedlings can be planted in polycarbonate greenhouses as early as February.

The question may arise: how to grow a radish in February, when it is still frosty outside? To do this, the soil should be moistened with warm water, the beds were hilled in a timely manner, and even without top dressing on such early dates, of course, is indispensable. Loose soil, the absence of pests and proper care will help you feast on your own radishes grown by yourself all year round.

The best varieties of radish for greenhouses

The best radishes in the greenhouse are Greenhouse Radishes, Eighteen Days, Early Red, and French Breakfast. These varieties are characterized by resistance, productivity, high germination and short maturity. So, when choosing from countless varieties of radishes, pay attention to the following for planting in a greenhouse.

The first seasonal vegetable to go on sale in the spring is the radish. With it comes the spring mood, and the body rejoices in the first vitamins. Do-it-yourself plants are always tastier and more environmentally friendly, so many people who have country cottage area, trying to breed early vegetables personally. In order for growing radishes in a greenhouse to be crowned with the desired result, you need to know not only agricultural technology, but also the characteristics of this crop, and the tips and tricks of experienced gardeners will also come in handy.

Growing radishes in a greenhouse is easy.

Radish is an annual plant, according to the biological classification, it belongs to the genus Radish, which, in turn, belongs to the Cabbage family. All parts of the plant are edible: roots are used in salads, leaves are used for soups. Even if you plan to eat only fruits, green tops will also need to be paid attention to while growing radishes in a greenhouse.

Photosynthesis takes place in the leaves of plants carbon dioxide from environment and its transformation into useful substances necessary for development), so their condition directly affects the formation of the underground part.

Interesting: For a project to study the characteristics of growing plants in weightlessness, conducted on the International Space Station, a radish was also selected. Scientists have considered that this vegetable, thanks to a short growing season (only 20-45 days), is excellent for breeding in space. In addition, the whole plant is eaten, which is very economical.

Radish is rich in vitamins B1, A and C, it contains iron, potassium and phosphorus

A little about the variety of varieties

Radish roots come in different configurations and different colors. The most commonly bred varieties are round or cylindrical (elongated) in pink or red-pink. There are also unusual colors: white, yellow, purple. When choosing such varieties for growing for sale (and for yourself), it is worth considering that the word “radish” is still associated with shades from the red range, so the original colors may not cause either delight or appetite.

What color will you choose?

The choice of varieties for planting is the easiest thing, it all depends on own desires. Hybrids (marked F1) are characterized by greater resistance to diseases and show increased yields. Varietal varieties have more pleasant taste.

Enthusiasts who prefer to grow radishes in a greenhouse made of own seeds, hybrids are not suitable. In order for the radish to bloom, it is not dug up, but left, over time, the plant gives arrows on which flowers appear, and then the seeds ripen. From three plants you can collect up to 100 g planting material.

You can harvest radishes in a greenhouse from March and throughout the season - until November. Varieties are characterized by the ripening period: early (up to 25 days), medium (35 days) and late (up to 45 days). You can grow one variety, then, for an uninterrupted supply of the table, it is necessary to sow new seeds every two weeks. You can choose varieties with different growing seasons: from 20 to 45 days, in which case you will need to plant seeds less often - once a month.

“French breakfast” has elongated dense root crops of soft pink color with a white tip, does not give arrows, belongs to the early ripe ones.
Dutch hybrids, for example, "Irene F1" and "Celeste F1" are characterized by round fruits of bright red color, varieties are intended for greenhouse cultivation, develop well in low light conditions, ripen 25-30 days after sowing.

Radish "French Breakfast" looks sophisticated and appetizing

From domestic varieties it is better to choose those that are intended for breeding in closed ground, for example, “Okhotsk” or “Lightning F1″. Also pay attention to characteristics such as resistance to bolting, the formation of hollowness in root crops, and disease resistance will not interfere.

Agricultural technology for growing crops

It is not difficult to breed radishes in a greenhouse, the plant is not considered capricious, it does not impose serious requirements on the conditions of detention. The main problems faced by vegetable growers in the process of growing crops:

looseness of root crops;
bitterness;
the formation of flower stalks before harvesting (taste spoils).

All problems are solved the right choice varieties and cultivation practices.

Soil preparation for planting

Work on growing radishes in a greenhouse begins with soil preparation. It is processed twice: in the fall and in early spring. In October, they dig to a small (10-15 cm) depth, loosen and add humus. Its consumption per square meter is approximately 3-4 kg.

You can use complex formulations, for example, azophoska according to the instructions, or apply superphosphate (50 g) and potassium salt (15 g) per square meter. spring work consist in fertilizing with nitrogen-containing compounds, for example, ammonium nitrate, which per square meter will need 12-18 g.

With improper cultivation, radishes begin to bloom instead of forming root crops.

The radish grows well in land that has previously grown tomatoes, cucumbers, potatoes, onions, or legumes. After cabbage and radish, it is not recommended to grow it, since there is a high risk of damage by mucous bacteriosis and powdery mildew.

To soil composition radish is not demanding, but plants prefer loose soils with a pH of 5.5-7.0. Too acidic earth is limed so that the plants do not get sick. On heavy soils, radish does well, but quickly produces flower stalks, which leads to the fact that the root crop becomes tasteless, or even inedible.

Tip: Do not fertilize radishes with manure, as this leads to the formation of shapeless root crops.

Seed sowing technology

Seedlings are not grown, since radish is considered a cold-resistant vegetable with a short growing season. Sowing radishes in the greenhouse is immediately carried out on the beds. After spring fertilization, the earth is loosened and furrows or holes are prepared. When growing in rows, the grooves are laid at a distance of 10-15 cm from each other. A more professional method is to use markers: radishes are planted according to the scheme 5 by 5 cm, 6 by 6 cm, and so on. Holes and trenches are shed with water, lightly sprinkled with ash, which is a source of potassium and trace elements.

To prepare the holes, special mats (markers) are used, but you can also use a rake with a suitable spacing of the teeth

In order for the seeds to hatch faster, they are soaked for a couple of hours in warm water. A number of vegetable growers, adherents of eco-farming, recommend using water in which eggs were boiled for these purposes. There are also modern way- the use of growth stimulants. In this case, it is better to give preference to natural and biological preparations, for example, "Zircon" or "Epin" show good results.

After the procedure, the seeds are slightly dried, carefully placed in the grooves, maintaining a distance of 2-3 cm between them. The depth of planting material is 2-2.5 cm. They are covered with soil from above and slightly compacted. Planting is useful to mulch with a layer of peat.

When to plant radishes in a greenhouse? Work begins in the first decade of March, when the soil is already warm enough (temperature not less than 0-3 ° C). Plants can be grown in heated greenhouses all year round. In other cases, suitable weather will have to wait.

For seed germination, an air temperature of 15 ° C is needed, so the planting is covered with a film at first. A layer of peat and a film provide the necessary temperature conditions. After germination, the film coating is removed, the planting is loosened and kept moist. Removing the shelter leads to a decrease in temperature, which is very good for plants. Sprouts are able to withstand frosts down to -4 ° C. In the future, it is not recommended to increase the temperature in the greenhouse above 16 ° C.

If the landing came out thickened, thin out by removing weaker specimens

The culture does not perceive the density of planting well, therefore thinning is necessary, especially in cases where the seeds were sown not pointwise according to the scheme, but in a row. The distance between the seedlings is left 2-5 cm, so that the plants do not give premature flowering, and the root crops do not become loose.

Caring for radish beds

This plant does not like excessive amounts of nitrogen fertilizers, so the radish is not additionally fed. In addition, root crops are prone to the accumulation of nitrates, but plants love watering. Soil moisture must be controlled to prevent radishes from becoming flabby.

Watering is carried out as needed. For the period from the appearance of sprouts to harvesting, one or two full-fledged irrigation should be carried out: 10-15 liters of water are used per square meter. Hybrids tolerate low light well, but varietal varieties may develop worse, although, in the spring-summer period, radishes have enough light.

Tip: radishes grown with soil moisture of 60-65% have large root crops and high palatability. Such earth, when compressed in the hand, is compressed, and when the palm is opened, it easily disintegrates.

Weeding is an obligatory item of agricultural technology

For preventive purposes, to protect plantings from cruciferous flea, which can destroy plants within a couple of days, dusting is carried out. wood ash mixed with lime and tobacco dust. Dressing is done once a week from the moment of the first shoots.

Harvested every four to five days. Usually returns occur within 1-2 weeks.

Tip: if some shoots are stretched out, you need to sprinkle the earth around the plant, that is, spud. The procedure is carried out during the period of “molting” of the root, when its skin cracks and it begins to thicken. Powders and hilling delay bolting and favor the formation of juicy root crops.

Features of breeding in the winter

Growing radishes in a greenhouse in winter is quite possible, but in the northern regions it is feasible only in heated greenhouses.

Important rules for winter gardening

AT middle lane heating is optional, but desirable in case of force majeure cooling. The greenhouse should be covered with polycarbonate. Radishes are planted in unheated rooms before winter, that is, at the end of October or November. In fully equipped premises, the culture is bred throughout the year.

Agrotechnics for growing radishes in a greenhouse in winter does not differ from the generally accepted one. The sown beds are also mulched and covered with foil. If the air temperature "overboard" drops below -7-10 ° C, add another layer of shelter (made of agrofibre). Although the culture is frost-resistant, the soil should be warm - from + 2-7 ° С.

Shelving makes maintenance easy

Especially useful for winter breeding dutch varieties that tolerate low light well. If you use them, you can do without additional lighting and save money on electricity bills. Based on the reviews of professional farmers who have been breeding radishes in the winter for more than one year, varieties can be distinguished:

“Cherryat F1″ – high yielding variety, not giving arrows; root crops are quite large, do not bitter, voids do not form in them.
“Sora F1″ is suitable for year-round cultivation, has large fruits, tolerates any daylight conditions well.
“Fanal” is an ultra-early variety: the radish ripens already on the 20th day after the sprouts appear.

Nuances of regular care

After the seeds sprout, the cover is removed in the morning to allow access to the light, and in the evening they are returned back. Usually sown by the point method: 6 by 6 cm, or 7 by 7 cm, the greater the distance, the earlier the radish ripens and has larger root crops. Dutch breeders give agrotechnical recommendations on packages with their products, it makes sense to use it.

Plant care comes down to watering, but the main thing is maintaining a certain regime of heat and humidity. Before the first shoots, the air temperature should be in the region of 20-25°C, then for three to four days it is sharply reduced to 5-6°C. After the cotyledon leaves unfold, but until the true leaves appear, the temperature is maintained at 8-10°C, after a couple of days a constant mode is set at 12-18°C. Humidity should be in the region of 60-70%. Before the formation of root crops, the beds are rarely watered, then the amount of water is increased.

Harvest of radish variety Sora F1

Growing radishes in a greenhouse is a simple event that allows you to get an early, environmentally friendly harvest for your relatives and friends. Of course, when breeding a vegetable for commercial purposes or for winter time more experience, skills and special devices will be required, but even beginner vegetable growers can do this procedure.

Planting radishes in a polycarbonate greenhouse can be of several types:

year-round in heated greenhouses;
from the beginning of February to the end of April for spring and summer use;
at the beginning of September for the autumn-winter season.

There are several planting techniques that allow you to reduce the time between the stages of harvesting the next wave of crops. Thanks to them, you can serve fresh radishes to the table almost continuously during the growing season.

What kind of radish is best to plant in a greenhouse

For growing in greenhouses, special varieties are created, which, unlike the usual ones, are capable of not letting arrows with seeds in low light conditions. However, when growing, it is better to use active lighting to provide 10-12 hours of daylight. Such varieties include Early Red, Dawn, Varta, Globus, Krasa, Saxa and others.

When choosing when buying which radish is better to plant in a greenhouse, pay attention to a number of properties:

Best before date. Expired seeds will not provide a good harvest.
The size. For planting, it is better to use seeds with a diameter of 3 mm or more.
Maturing period. According to the duration of the vegetative period, early-ripening (18-25 days), early (25-30 days), mid-ripening (30-40 days) and late (more than 40 days) radishes are distinguished.

For 1 m2 of beds, about 5 g of seeds will be required. You can plant several varieties at once different term ripening, and in your garden, new portions of the crop will almost constantly ripen in turn.

When to plant radishes in a greenhouse

In heated polycarbonate greenhouses, radishes can be planted around the clock, planting new seeds between rows after harvest or mid-season for 10-15 crops per season.

Spring planting is carried out from the beginning of February to the end of April. It can be planted in unheated greenhouses if the soil has become soft to a depth of 3-5 cm. Usually this is the second half of March or the first half of April. The timing of the first harvest will depend on temperature and daylight hours:

planting radishes in a greenhouse in February will require fruits to ripen for 1.5 months;
planting radishes in a greenhouse in March will produce a crop in about 35 days;
planting radishes in a greenhouse in April will speed up ripening, the crop can be harvested in less than a month.

In early September, radishes are planted for autumn, and in heated greenhouses for the entire autumn-winter period.

How to prepare and plant radish seeds

If the seeds are not the same in size, then the largest ones are selected, sifting the fines through a sieve with holes of 2.5-3 mm. In the absence of a sieve, you can place the seeds in a salt solution (dissolve 1 teaspoon in 250 ml of water) and select only those that have sunk to the bottom.

To speed up the emergence of seedlings, the seeds are washed with a weak solution of potassium permanganate. Can be immersed in hot (50°) water for 20 minutes to prevent dry rot. Then the seeds are left on a damp cloth until the sprouts peck.

Seeds are usually sown in meter-wide beds. Shallow grooves are made, located in 7 cm increments. Seeds are placed in them at a distance of 1.5-2 cm, so as not to thin out later, and sprinkled with a 1 cm layer of soil.

Delicious, slightly spicy radishes are popular throughout the year. With the right approach, a radish growing business can bring good profits. It is especially profitable to sell a vegetable in winter, during a period of limited supply. To get a good harvest, it is necessary to create conditions in the greenhouse that are as close to natural as possible.

For the greenhouse, you need to choose varieties that have good resistance to external influences. A significant factor is the length of the growing season.

Table of radish varieties

By alternating planting seeds, you can harvest throughout the year.

Not all seeds need to be processed before planting. On the shelves of stores there are seeds that are completely ready for planting.

Types of seeds

Hybrid - treated with drugs that protect against diseases and pests. Hybrid seeds can be sown dry.
Varietal - collected independently or purchased from neighbors (sellers in the markets) seeds. They can be infected with fungal or viral diseases, so they need to be processed.
Inlaid - seeds in a protective shell. The shell consists of growth stimulants. Do not need processing.
Dragee - coated with peat-mineral mixture. The mixture provides protection and nourishment. It is not necessary to process pelleted seeds.

The purpose of the treatment is to decontaminate and further stimulate growth. One of traditional methods- soaking in a weak solution of potassium permanganate.

Also, disinfection can be carried out using the immunocytophyte preparation (one tablet per 100 ml of water). Processing time - from one to 12 hours.

The following substances are used as growth stimulants:

After soaking, the seeds should be scattered on a paper sheet to dry.

Soil mixtures

It is necessary to prepare the soil in advance, since autumn. After harvesting, it is necessary to remove the remains of plants and dig up the ground, add humus.

There are several options for preparing soil mixtures. For radishes, the following ratios are optimal:

40% field land plus 60% manure humus;
20% lowland peat plus 40% manure humus plus 40% sod land;
60% manure humus plus 40% sod land;
50% sod land plus 50% greenhouse land.

Planting a radish

For an early harvest, radishes can be planted from mid-January. The optimal temperature regime for radishes is from 0 (at night) to +15 degrees (during the day).

After a few days, you need to remove the film, dig up the soil and mix it with mineral fertilizers. The planting depth of radish is 2 cm, the distance between seeds is 2-3 cm, the distance between rows is 8-10 cm. Uniform planting of seeds eliminates the need for thinning. After planting, the land is covered with polyethylene for several days so that the seeds can acclimatize.

Choose the right variety of radish. Seeds intended for planting in the ground, in greenhouse conditions they can shoot.
In no case should you sow the seeds too thickly in the greenhouse. Even thinning may not save from such an error.
Be sure to use humus or compost for additional seed nutrition.

The optimal distance between rows is the width of the palm.

Care

Radishes are very hardy. The gardener will need to carry out only a few manipulations in order to reap a rich harvest. After the seedlings emerge, the radishes should be thinned out. If the small sprouts grow too close together, the radishes can turn out small and tasteless. Thinning also helps prevent arrowheads from appearing.

As an additional food, you can use peat, nitrogen fertilizers, humus. Helps protect future crops from pests folk remedy: mixture of tobacco dust and ash. Mandatory stages of care are weeding, loosening the soil, airing.

If the temperature outside the window has dropped below normal, protect the seedlings with additional arcs placed inside the greenhouse and covered with polyethylene. Instead of polyethylene, a dense non-woven material can be used.

Greenhouse heating methods

Biological- laying half-rotted manure on the bed. A 20-cm layer of earth is poured over the top of the manure.
Electric— use of a special heating cable. A protective mesh is laid on the ground layer, then a cable, then another mesh, a 5-cm layer of sand and 15-20 cm of fertile soil.
Water heating- pipes are connected to the boiler, forming a closed heating system.
Furnace- attached to the oven horizontal pipes passing throughout the greenhouse. Installed at the end of the system vertical pipe. The smoke comes out through this pipe.
Electric convectors, infrared heaters, radiators. They are installed around the perimeter or on both sides of the beds and are turned on as needed.

Harvest

The growing season of greenhouse and ground radish is somewhat different: the greenhouse vegetable ripens later. On average, you can get a crop 2 months after sowing. The process is also affected by the variety of the root crop, the level of lighting and temperature conditions. Gardeners do not recommend delaying harvesting: you need to harvest radishes when they reach medium size, become juicy and acquire a color characteristic of the variety.

Tip: Water the plants a few hours before harvest. Optimal combination: watering in the morning and cleaning in the afternoon.

The harvested crop needs processing. If you do not plan to sell the vegetable immediately, along with the tops, trim the leaves. Then rinse the radish cold water and dry slightly. Root vegetables can be stored in the refrigerator for 3-4 weeks.

There is a technique that allows you to store vegetables for a long time. Radishes fit into wooden boxes, the bottom of which is covered with polyethylene. Vegetables are sprinkled with a mixture of peat and sand. Sand-peat mixture protects root crops from rotting.

A few tips for aspiring entrepreneurs

How more land, the more radishes. Gradually increase production.
To ensure the availability of production, plant seeds every 1.5-2 weeks.
Bet on quality: choose varieties that produce delicious fruits.
Work on holidays.
In the fall, you can go on vacation so as not to sell radishes at dumping prices.
The greatest demand for radishes will be in winter and summer.
Grow classic varieties. Add exotic little by little, on trial.

Growing radishes is a business that you can really start from scratch. Products collected on own site, is not taxable. Start with small sales, and if it works, register as an individual entrepreneur. In this case, you will be able not only to sell root crops on your own, but also to supply products to stores and to the market. Be sure to indicate the scope of activity during registration: agricultural production. Producers of agricultural products enjoy the support of the state.

Video - Growing radishes in a winter greenhouse

There is an opinion among gardeners-gardeners that winter is the season when vegetable crops can only be consumed in the form of preservation or pickles. However, it is not at all necessary to wait until the weather allows planting in open ground. An excellent alternative to pamper your loved ones with fresh gifts of nature, plucked directly from the garden in winter, is growing vegetables in greenhouse conditions.

Especially unpretentious in this regard, radish is a growing technology that does not cause any particular difficulties even for amateur gardeners. The root crop ripens quickly enough, and it is hardly possible to imagine an earlier spring dish from fresh vegetables than a radish salad. Plus to everything radish is rich in various minerals and vitamins of groups A and C.

This vegetable can rightfully be called the most unpretentious root crop. As soon as the snow melts, you can immediately sow radish seeds in open ground. Even a slight frost will not harm him, but in order to get the most early harvests Can you grow radishes in a greenhouse?.

Positive properties of radish

The radish belongs to annual plants which are planted earlier than other vegetable crops. After only one and a half months, you can enjoy the first harvest of a healthy, and most importantly, delicious root crop.

The radish contains useful components ranging from fiber, acids to organic basis, magnesium, potassium and ending with useful vitamins of groups C and A, as well as other trace elements necessary for the proper functioning of the human body.

This vegetable crop has a relatively mild taste, with a slight bitterness. That is why it has come to the taste of many gardeners who grow it on personal plot in a greenhouse. Wherein radish grown in greenhouse conditions allows you to enjoy its taste for all year round .

Growing specifics

This root crop, although unpretentious in care, still prefers for growing a place with a lot of light and heat, as, in principle, and other vegetable crops. Lack of minimum growth requirements for radishes will cause the fruit to grow small. I would like to note that the greenhouse method of growing radishes requires additional lighting.

If we talk about temperature, then the radish is quite unpretentious to it. She easily tolerates frost up to 3°C. But at temperatures above 25°C, the fruits begin to wilt and become empty inside. Optimal temperature regime for growing radishes, 18–20 ° C is considered.

For getting good harvest It is important to choose the right soil. Sowing radishes in acidic soil can lead to clubroot disease. Also special attention should be paid to the presence of a high amount of nitrogen and potassium in the ground. Otherwise, the fruits may not ripen, and the foliage will turn pinkish.

Soil preparation

Soil preparation is one of the most milestones. The yield will depend on how well it goes, in particular appearance and the taste of root vegetables.

The preparatory stage must be carried out in advance, about six months before planting the seeds. To do this, you will first need to dig up the soil, then add mineral-rich fertilizers to it. The feed material should consist of 40 g of phosphates mixed with 15 g of potassium chloride.
You need to make sure that the soil in which the radish will be planted has a neutral acidity. In an acidic environment, it is advisable to add about a bucket, maybe a little more, of compost per square meter of soil. This will guarantee high yield vegetable culture.
You can also prepare a bed for sowing seeds. Its width should vary up to one meter, and the soil should be loose and moist.

Preparation and selection of planting material

Before planting radishes in the greenhouse, it is important to carefully select and prepare the seed. In this case, the main attention should be focused specifically on the variety of vegetables:

Ultra-early variety - the ripening period, which is less than a month (18-25 days). At the same time, the most popular among gardeners are the varieties: "Children's F1", "20 days" and others.
Early ripe variety - root ripening occurs within 25-30 days. Varieties are popular here: "Dawn", "Ruby", "Camelot" and the like.
Mid-season variety, the growing season of which ranges from 30 to 40 days. The best varieties radish: "Icicle", "Red Giant", and others.
Late-ripening variety - ripens more than 40 days. This category includes the variety "Dungansky" and "Zenith".

I would like to note that there are varieties bred specifically for growing radishes in a greenhouse, which include "Early Red", which bears fruit throughout the year. The main thing is to create the right conditions.

Regardless of the variety chosen, radish cultivation in a greenhouse begins in the last months of winter. However, at the first stage, you need to prepare the greenhouse itself, which is covered polyethylene film. She must be in this state. certain time which will warm up the ground. If necessary, you can prepare the beds.

The radish seeds themselves need to be selected, it is better to do this in advance. Large seeds with a diameter of 3 mm are considered the best. Such material for planting will give a friendly ripening of the crop, and the fruits will be large and even. Also it is important that the seed is not expired. Small or expired seeds will not give the desired result, and the grown radish will be medium-sized and bitter.

Before planting the seeds directly, they can be placed in a damp cloth so that they hatch, and in order to avoid infection of the seedlings with "dry rot", the seeds are heated in 50 degree water for 20 minutes. This will also allow you to get earlier shoots.

Sowing seeds

At the stage of choosing a quality seed, the seeds can be sifted through a sieve with small diameter holes (up to 3 mm). So you can quickly select high-quality radish grains. At the next stage seeds are treated with a solution of potassium permanganate and water.

Thanks to this method of cultivation, thinning of sprouted seeds will not be necessary in the future. In this case, the change should not be too deep into the ground. It is enough to simply sprinkle them with a centimeter layer of soil.

Caring for radishes in a greenhouse

After sowing the planting material, it requires proper care for itself so that the crop is large and juicy. Successful harvest will be if the greenhouse supports optimal conditions- temperature and humidity. When building a greenhouse in compliance with all technologies, this is easy to achieve.

Harvesting

Radish harvesting is started when the size of the root crops reaches more than 2 cm in diameter. Usually harvesting takes place in several stages with a break of up to 20 days. Medium radish yield per square meter, reaches two, sometimes more than a kilogram.

Even before the start of harvesting, it is possible to sow new radish seeds between the rows. Moreover, if the planting option 5 × 20 cm was used, then the seed is planted immediately at the first stage of collecting root crops. In this manner you can get a continuous crop of radishes in a greenhouse.

Thanks to this growing technology, you can harvest up to 10-15 crops, and this is up to 30 kg from one square meter. And given that radish is not a cheap vegetable (in the spring its cost is as high as possible), you can not only provide your family with vitamins, but also, if you wish, earn some money to buy seedlings of other vegetable crops.
