How to shape cucumbers in polycarbonate greenhouses

In order to achieve a good harvest, it is important to pay attention to each plant grown. That is why, before making the formation of cucumbers in a polycarbonate greenhouse, it is necessary not only to carefully select the variety, but also to read the instructions for caring for it.

Formation of cucumbers in a polycarbonate greenhouse

Reasons for forming

All cucumber varieties are divided into 2 groups:

• standard;
• hybrid (add f1 to their names).

unconventional, new hybrid varieties should not grow without proper care, because each of them has its own characteristics of forming a bush in a greenhouse. .

• If the territory and plants are not well-groomed, it is difficult to get there for pollinating bees. As a result of this, there are few ovaries on cucumbers.
• Proper plant growth allows you to rationally use the interior of the greenhouse.
• Overgrown bushes in a polycarbonate greenhouse, obscure other plants from sunlight. This affects their development and yield indicators.
• All the forces of the plant go into shoot growth, so if the length of the lash is large, the quality and quantity of fruits leaves much to be desired.
• Properly formed cucumber lashes greatly facilitate the care and harvest.
• Timely pinching extends the fruiting period.

General rules for forming

More than 50 types of cucumbers cultivated in the Russian Federation are used for cultivation in open and greenhouse conditions. Correctly forming cucumbers in a polycarbonate greenhouse is not difficult: starting from 2 weeks after planting, the plant should be tied to a trellis.

Twine should be of high quality and non-slip. The lower end is passed under the first sheet. Make a free loop: with growth, the stem is compacted. You can’t pull on the blindfold too much: with strong winds, the bush will be torn out of the soil.

Scourge plants form in the first 2-3 months after planting. When the fruiting period begins, the grower should not allow the plantings to grow densely next to each other.

If the greenhouse is heated, no more than 12-15 fruits are left on the central stem of the seedlings planted in January. At the same time, the ripening fruit should be no more than 3. As the sunny day increases, the number of fruits is allowed.

If large leaves have formed in the upper part of the cucumber creeper, thin out so that the lower tier is better illuminated.

Pinch

Parting will provide light access to the plant

Partitioning is one of the methods of formation, involving the removal of excess leaves and ovaries from the main stem. Due to this, the nutritional energy of the bush is generated and sent to the desired area. If there are a lot of branches on the cucumber, they overshadow each other, as a result, the bush grows faster to get more sunlight. In order to prevent this, they make stepsoning. In greenhouse conditions, it occurs as follows:

• In the lower part of the bush, all flower primordia and lateral shoots to 4-5 leaves are removed. This is done so that the lower part has full ventilation of the stem. This is the only way to avoid the development of diseases and decay. This stage is called the prophylaxis of root rot.
• When the plants grow to 0.8-1.0 m, 2-3 shoots of no more than 20 cm in length and 1-2 leaves are left on the bush.
• As soon as the cucumber reaches a height of 1.3 m, the lateral processes should be approximately 35-40 cm, 2-3 ovaries and the same number of leaves are left on each of them.
• At a height of 1.5 4 leaves and 3-4 ovaries should remain on each side shoot.
• If the lashes have grown to the maximum possible height, they are immediately tied up. There is a slight exception possible with a low greenhouse ceiling.In such a case, the lashes are thrown down for further growth. When less than 20 cm remains to the ground, pinch it to stop development.

Particular attention is paid to thinning leaves on the upper part. This is done as carefully as possible so as not to harm the bush.

Pinching and pruning

It is better to carry out such actions in the morning. Then during the day the process of plant restoration takes place. Cucumbers are characterized by rapid growth, therefore, along the lash growth, flower ovaries develop in the lower part of the stem. They take a lot of energy from the main shoot, but do not bear fruit. For normal root system formation, these sinuses are immediately removed.

When harvesting fruit, it is important not to change the direction of growth of the lashes. This leads to yellowing of the leaves, which are immediately removed.

Pinching rules

• The procedure is carried out for young shoots to prevent their growth. If you pinch whips longer than 20 cm, the plant is severely injured.
• To quickly restore the leaves and shoots, use special scissors or a sharp knife.
• Leaves are cut as close to the stem as possible. Stumps cannot be left: they can cause powdery mildew.
• If there are a lot of empty ovaries on the bush, you can not remove them. At the same time, the earth is dried, then from these barren flowers all useful substances will turn into fruits.
• The stem is wrapped around the cord in a clockwise direction 1-2 p.in Week. This is done carefully: it is fragile and breaks easily.
• Pinch the antennae, damaged inflorescences and cucumbers. The antennae take away most of the energy and nutrients, thereby interfering with the development of plants.

When pinching and lashing the lashes, it is important to follow all the rules. Seedling is a young unrooted plant, any manipulations or improper care with it violate the root system.
