How to pinch cucumbers in a greenhouse step by step with photos and videos

Care for cucumbers in the greenhouse and open ground should take into account agrotechnical rules. If you want to get optimal vegetable yields, then you need to have an idea of \u200b\u200bhow to pinch cucumbers in a greenhouse. The procedure is especially important for the formation of cucumber vines.

Benefits of cucumbers for humans

Cucumbers are the first to ripen from vegetables in the beds. Although the concept of ripening for them is quite relative. As soon as small greens appear, a person immediately picks them for eating. And rightly so, because the fruits of the plant contain many useful substances that help:

• quench your thirst;
• to remove toxins from the body;
• strengthen the immune system;
• digest animal proteins.

But we do not only think about he alth when fresh cucumber salads appear on the table, but also about how tasty this product is. You can't imagine a summer menu without cucumbers. They are good in marinade and brine for the winter. Only a rich harvest of a vegetable will allow you to stock it for the winter. To do this, you need to correctly pinch the cucumbers, take care of them in the greenhouse.

Features of the structure, development of the plant

Since the tropics are the birthplace of the cucumber, much of the structure of the vegetable is from liana-like plants:

1. The root system of a vegetable is characterized by branching. At the same time, the depth of the roots is small from thirty centimeters. With sufficiently moist soil, the vegetative growth of cucumbers is reflected in the development of additional root suckers.
2. The stem of the vegetable is creeping, branching with many tendrils, with which it catches on the supports and grows upwards.
3. Both male and female flowers are formed on the stem, collected in inflorescences of five or six pieces. They are formed in the axils of the upper rudimentary leaves. Most female flowers are formed not on the central shoots, but on the lateral lashes of the first and second order
4. If this type of plant requires cross-pollination, there are parthenocarpic varieties that develop without pollination. They have more female flowers than male flowers.
5. The fruits of the plant can ripen soon, two to three weeks after setting. They are oval in shape and green in color. Inside the cucumbers are seeds that are not ripe at first, but as the growing season grows, plants are ready for reproduction.

To obtain full-fledged, tasty cucumbers, it is necessary to create favorable conditions for their development. The vegetable will bear fruit at a constant temperature of 25-30 degrees above zero during the day, and at night - at 15-18 degrees.

Freezing for cucumbers is fatal. Therefore, it is better to grow cucumbers in a greenhouse, a greenhouse. The air temperature will not fluctuate sharply there, there will be enough light and air. Indoors, a vegetable develops successfully if it is grown in accordance with the requirements of agricultural technology. In regions with a cold climate, planting a vegetable crop in greenhouse soil is the only way to grow a thermophilic garden crop.

Cucumber care consists of:

• watering with warm water;
• fertilizing with nitrogenous and phosphorus-potassium fertilizers;
• loosening the soil;
• pinching the tops of the shoots.

Pinching cucumbers in a greenhouse is an important procedure that has a positive effect on the yield of vegetable crops, the taste of greens.

Benefits of pinching cucumbers

From the peculiarities of the structure and development of the cucumber crop, it is clear that the shoots need pinching until the plant blooms in the greenhouse. Otherwise, the growth of lashes will be chaotic, and the plant will not please with fruits. The advantages of the procedure include:

• stimulation of the formation of fruit ovaries;
• improving the level and quality of cucumber crops;
• acquisition of delicate taste by cucumbers, without bitterness;
• creating conditions for improved vegetable growth in the greenhouse.

But you need to know that pinching cucumbers must be carried out according to the rules, because an incorrectly performed procedure will lead to crop loss.

How to pinch cucumbers in a greenhouse

In order for the plant to be cared for correctly in the greenhouse, to contribute to obtaining a quality crop, it is necessary:

• partially remove male flowers;
• eliminate tendrils by tying whips to trellises;
• pin off shoots, leaves, creating conditions for branching stems.

Growing cucumbers in a greenhouse, you need to understand how pinching will affect the state of the plant, its vegetation. The pinching scheme is built in accordance with the variety of the vegetable plant. If cucumbers are parthenocarpic species, then it is not necessary to leave male flowers on the vine. For those cucumber plants that are pollinated by insects or themselves, the same ratio of male and female flowers is needed.

Pinch the cucumbers in the greenhouse as follows:

1. As soon as the fifth true leaf appears, flowers, mustaches, and side shoots are removed from the lower sinuses.
2. In the future, start pinching cucumbers in the greenhouse as soon as the seventh or eighth leaf grows. Then two shoots are removed from the side of the main stem.
3. After the eleventh leaf, it is important to remove the top of the main shoots so that the side shoots actively begin to grow, new fruits form.
4. For parthenocarpic types of vegetables, after planting, they form a bush into one stem. As soon as it reaches half a meter in length, all other branches, flowers, mustaches at the bottom of the central shoot are cut off. And then the lateral processes must be pinched to the first leaf.

Cucumbers in the greenhouse, as a rule, grow quickly, and the first harvest does not take long. An important factor for their cultivation will be the density of planting, the degree of illumination of plantings. To provide favorable conditions for vegetative growth, knowing how to pinch cucumbers in a greenhouse will help step by step.It is best to use special cutting instruments for the procedure.

Features of the procedure for self-pollinated varieties

Branching plants, pollinated by bees or on their own, start late, so it will take a long time to wait for cucumbers in a polycarbonate greenhouse. If you pinch the top of the main shoot, the plant will begin active growth, forming ovaries. Therefore, the first pinching of cucumbers is carried out over the second true leaf, leaving a stump of half a centimeter. After that, shoots with female flowers appear on the sides.

Pinching them, activate the appearance of branches of the second order. It is they who will give forty percent of female ovaries.

Blinding cucumbers, pinching, removing all flowers and leaves located in the axils below the sixth leaf, is a must. Then they will not take the nutrients necessary for fruit setDuring the procedure in greenhouse conditions, it is important to remember that one or two green leaves are needed for one ovary of cucumbers.

Parthenocarpic view: is it necessary to pinch cucumbers in a greenhouse

For indoor hybrids with a predominance of female flowers, pinching is also necessary. It is carried out in a slightly different way:

1. When the stem of the liana fixed on the trellis reaches a height of fifty centimeters, then the removal of all shoots, ovaries, flowers begins in the lower part. This creates a blind zone.
2. Pinch the side shoots higher up the stem, keeping one ovary and a pair of leaves each.
3. At a height of one to one and a half meters, in two to four knots, you can leave two ovaries with two to three leaves.
4. If the growth of the cucumber stem continues, already at a height of more than one and a half meters, you can pinch the whips above the third leaf, saving up to three ovaries.
5. All elongated shoots of cucumbers are then thrown over the trellis, allowing them to move down. As soon as the distance to the soil reaches twenty centimeters, the growing point on the central stem must be removed.

When pinched properly, greenhouse vegetables will produce more cucumbers than outdoors.

How to care for a vegetable in a greenhouse

If you plant cucumbers indoors, they ripen fifteen to twenty days after the fertilization of the ovary.

To do this, they need to organize:

1. Water. It is better to water the vegetable in the evening every day. As soon as flowers appear, the frequency of watering is reduced. During the procedure, they try to soak the soil layer as deep as possible.
2. Shower. On hot days, plants are sprayed, keeping the air humidity in the greenhouse about ninety percent.
3. Feeding. First, be sure to water the cucumbers with a solution of mullein in a ratio of 1:8, then bringing the concentration to 1:4. From mineral fertilizers, the use of ammonium nitrate (fifteen grams), superphosphate (forty grams) and potassium chloride (ten grams) helps. The concentration of substances is increased during the fruiting period of the vegetable. Fertilize once every two weeks.
4. Rejuvenation. The stalks of cucumbers, bare at the bottom, are lowered to the ground and folded into a ring. A week later, they cover them with earth.

To increase the level of carbon dioxide in the greenhouse, heaps of fresh mullein are laid out in the aisles or barrels filled with organic solution are placed. If you follow the rules of agricultural technology, then without pinching you can not grow cucumbers in a greenhouse.And there should be no doubt whether it should be done or not. And how to pinch cucumbers in a greenhouse, you can see a step-by-step photo. Gardeners believe that it is necessary to carry out the procedure, but not randomly, but in compliance with the rules.
