Growing cucumbers in a polycarbonate greenhouse: care, technology how to do it right

Growing cucumbers in a polycarbonate greenhouse is quite a serious job that requires a lot of cost and effort from a person. Growing them in a greenhouse is much more difficult than growing them outside, as you will have to create the best conditions for the plants yourself.

It is also necessary to take into account all the characteristics and properties of cucumbers. Therefore, before starting work, you need to learn how to properly grow cucumbers in a greenhouse.

Choosing the right variety

Before you learn the secrets of growing cucumbers in a greenhouse and start breeding them, you should choose a plant variety. Cucumbers are divided into several groups, among which special varieties for greenhouses stand out. At the same time, they are quite diverse and have their own characteristics.

Emelya

Pretty young early ripe variety of cucumbers for private gardens and greenhouses. Since the technology for growing cucumbers in a greenhouse is very simple, even people who have not done this before can grow them.

Fruits begin to ripen 30-45 days after planting seedlings in the soil. The bushes of this variety are indeterminate and vigorous. Covered with lots of green leaves.

Fruits reach 20 cm in length. The taste of cucumbers is not bitter and even slightly sweet. Emelya boasts maximum yields, which is 15 kg per square meter. If you know how to care for cucumbers in a greenhouse, you can increase the yield several times.

This variety also stands out for its good cold tolerance, so you don't have to worry about what temperature should be when growing cucumbers.

Courage

An early ripe type of cucumber that grows very quickly and ripens within 40 days. The plant does not need care, so it is ideal for people who do not want to figure out how to care for cucumbers. However, the optimal temperature for growing must still be maintained.

On one Courage bush more than 10 ovaries can form. The size of the largest fruits is 15 cm in length, and the weight is 150 grams. They are dark green in color and often have a bumpy surface. The peculiarities of the fruits include their safety, which is two weeks. Courage also stands out for its resistance to many common diseases, which include:

root rot;
cucumber mosaic;
downy mildew.

Masha F1

An early variety that will ripen a month after planting in a greenhouse. The bushes of the plant are determinate and undersized. They do not need a garter to additional supports and pinching. Cucumbers are covered with small green leaves and inflorescences. All flowers on cucumbers are female, so gardeners don't have to think about pollinating them. The fruits of this variety are cylindrical.

On average, fruits grow up to 5-7 cm in length. However, people who know how to take care of greenhouse cucumbers get bigger harvests.

It is recommended to plant seedlings in early spring, in early or mid-March. Bushes do not like too low temperatures, so the minimum temperature for cucumbers should be at least 15-20 degrees Celsius. If it is lower, then the plant will not be able to grow and develop normally. Also, when growing, you need to monitor the length of daylight hours. It should be about 14-15 hours a day.Such conditions are most suitable for a good harvest.

Mazay F1

Early maturing variety recommended for planting in tunnels or greenhouses. However, the most popular is the cultivation of cucumbers in a polycarbonate greenhouse. Some residents of the southern regions of the country also plant them in open ground, but in this case, the bushes may suffer from possible night frosts.

Mazay differs from other varieties in the size of fruits that grow up to 15-17 cm. The weight of each cucumber reaches 140 grams. Zelentsy are covered with rather large tubercles and have a cylindrical shape. Taste qualities are distinguished by the complete absence of bitterness.

To obtain a quality crop, the correct agricultural technique for growing cucumbers in a greenhouse must be used. If you take care of this variety poorly, then there will be very few fruits on the bushes.

Marinda F1

Quite a popular early maturing variety grown in film greenhouses and greenhouses. The first cucumbers appear on the bushes 50 days after planting the seedlings. Marinda does not need careful care, so even beginners can grow such cucumbers in a greenhouse.

The bushes of the plant are not too dense, which makes it easier to harvest later. The fruits are colored dark green, their weight reaches 80 grams, and the length is 10 cm. The pulp of the fruits is quite crisp and hard. More than 40 kg of young cucumbers can be harvested from one square meter.

Marinda is resistant to many diseases. She rarely suffers from spotting, scab, mosaic and powdery mildew.

Greenhouse preparation

To grow cucumbers in a greenhouse, you need to carry out preparatory work.

Wash

Before growing cucumbers in a polycarbonate greenhouse, everything must be thoroughly washed:

glasses and films are washed with ordinary soapy water;
iron products and PVC are best cleaned with a pre-prepared solution of vinegar;
polycarbonate is cleaned with a weak manganese mixture.

After completing work in the room, you need to air it out so that everything dries faster.

Preparing for disinfection

To prevent grown cucumbers from getting sick, disinfection should be carried out in the greenhouse in advance. First, mechanical processing is carried out. To do this, it is recommended to carefully inspect the greenhouse and remove all the moss that often appears in the greenhouse ventilation. Then all the walls are treated with iron sulphate to get rid of the remaining spores.

You also need to clear the greenhouse of the remaining tops. It should be taken outside and burned, as it may contain pathogens.

Lime processing

Polycarbonate greenhouse can be disinfected with lime. The solution is applied to the entire structure inside and to the soil. It is also recommended to process inventory and tapes for watering seedlings.

Preparing a lime mixture is quite simple. 500 g of lime is added to 10 liters of water, after which all this is infused for a day. Then the solution is applied with a conventional brush to the surface of the structure. Particular attention should be paid to crevices, as they most often contain harmful bacteria. After that, the earth is sprayed with a spray gun.

Disinfection with a checker

It is recommended to use a gray checker, because during combustion it releases gas, with which you can clean even the most inaccessible places.During disinfection, it is recommended to use a special mask and rubber gloves. It takes about 3 days to keep the greenhouse in smoke, after which it can be aired.

Disinfection with a checker is carried out if the temperature in the greenhouse for cucumbers is between 12-15 degrees Celsius.

Use of biologics

Growing and caring for cucumbers should be carried out in a greenhouse prepared and processed in advance. Quite often, special biological preparations are used for its disinfection. Their main task is to improve the quality of the soil and the destruction of all pathogens. Biological products are completely safe, so it is not necessary to ventilate the greenhouse with cucumbers after using them.

It is recommended to carry out such disinfection in the fall, and not in the spring, a few days before planting seedlings in the ground.

Soil preparation

Before you study the features of growing cucumbers in a greenhouse, you need to familiarize yourself with the rules for tillage. This is done to completely cleanse it of pathogenic microorganisms. There are several most efficient processing methods.

Freezing

This method is the simplest and is therefore popular with most vegetable growers. The earth must be placed in a dense cloth bag and kept at low temperatures for several days.

Some don't know what is the best temperature for freezing. It is best to carry out this procedure at a temperature of -20 degrees. Freezing is done twice to get the best result.

Warming up

If the temperature in the cucumber greenhouse is very high, then many pests will not be able to live under such conditions. However, elevated temperatures can also adversely affect young bushes. Therefore, it is recommended to warm up only the soil before planting seedlings. There are two ways to perform proper warm-up:

Steaming. The most common heat treatment method that many gardeners love to use.To steam the soil, it is necessary to heat a bucket of water on a gas stove with a grate installed on top, on which the soil is placed in a small bag. It takes an hour and a half to complete the procedure.
Ignition. The soil is completely filled with hot water, after which it is placed in a special container and placed in the oven, which is heated to 100 degrees. Ignition is carried out no longer than an hour.

Insecticide use

Quite often, growing cucumbers in a greenhouse is carried out in soil that has been treated with insecticides in advance. Such drugs are often used during the fight against pests in the ground. Before applying them, the soil should be well moistened and loosened so that the drug can better mix with the ground.

It is necessary to use insecticides a few months before planting seedlings in the soil. However, it is recommended that you follow the instructions exactly to get it right.

Using fungicides

Some people treat the soil with fungicides before growing cucumbers in a polycarbonate greenhouse. These preparations consist of bacterial groups that improve the immunity of young cucumbers and help cleanse the soil of bacteria. The most commonly used solution is Fitosporin. To prepare it, 20 ml of the drug is mixed with 8-10 liters of water.

Preparation and sowing of seeds

Sometimes even careful care of cucumbers in a polycarbonate greenhouse does not allow for a good harvest. Often this happens if unprepared seeds were planted in the soil. There are several methods for preparing planting material.

Soaking

Cucumber seeds can take a long time to germinate, so it is recommended to soak them before planting. To do this, all seeds are placed in moistened cloth bags. They stay in them for a day.During this time, the water must be changed periodically so that it is always clear. The next day, the seeds are taken out of the bag and dried in the sun.

Germination

Sometimes when growing cucumbers in a polycarbonate greenhouse, people have to wait a long time for the first shoots to appear. This process may be delayed if unsprouted seeds were planted. To do this, they are placed in a plate, which is covered with filtered paper or a thick rag. Then the seeds are watered and placed for 2-3 days in a dark place. During germination, care must be taken to ensure that the seeds do not dry out completely.

Landing

Cucumber farming and planting are quite simple. It is recommended to plant them in late or mid-spring. If sowing is early, it is recommended to sow dry seeds, as wet ones can deteriorate if the soil is not warm enough. Planting is recommended if the temperature for cucumbers in the greenhouse is 15-20 degrees.

Holes are made with an interval of 30 cm, and rows - 40 cm. No more than three seeds are placed in one hole, the distance between which is 10 cm. It is not worth planting cucumbers thickly, as you will often have to thin out thickened crops. Also, densely planted bushes do not develop fruiting lashes.

Care

Not everyone knows how to properly care for cucumbers in a greenhouse. They should be cared for immediately after planting.

Irrigation

Proper care when growing should include regular watering of cucumbers in the greenhouse, as they love moisture. If you water cucumbers too infrequently, then the yield will be poor.

When the weather is too hot, the bushes need more liquid, so it is recommended to water them 2-3 times a week. In the first weeks, you can spend one bucket per square meter.However, when the bushes grow up, the water consumption increases and you have to spend a bucket on one cucumber bush.

Don't water the bushes too often as this increases the humidity level in the cucumber greenhouse.

Soil loosening

Care for cucumbers in a greenhouse should be accompanied by loosening the soil. It is carried out after each watering, since after drying the earth is covered with a dense crust. During loosening, you can not shift the loops of the plant. They can only be moved a little to the sides or lifted. At the same time, this is done very carefully so as not to accidentally damage the cucumbers.

Feeding

People who are familiar with the secrets of growing cucumbers in a polycarbonate greenhouse regularly fertilize the soil. This can improve yield several times over.

In order for the bushes not to suffer from a constant lack of nutrients, they must be fed 4-6 times in one season.For the first time, fertilizers are applied immediately after the appearance of the first shoots. The most commonly used organic and mineral fertilizers: chicken manure, mullein or ash.

Such fertilizers are quickly absorbed by grown cucumbers. The next time feeding is carried out only after 15-20 days.

Conclusion

Growing cucumbers in a greenhouse is much easier if you love doing it. To do everything right, it is recommended to study the rules for growing bushes in advance. It can also help to grow cucumbers in a greenhouse video, which describes this process in detail.
