The formation of cucumber, zucchini and pumpkin. Topping
Chestnuts bloomed, which means that it is time to plant heat-loving crops, including cucumbers, zucchini, pumpkins, in the open ground. Such an agrotechnical technique as pinching helps to make the crop increase fruiting. It is not carried out on all varieties and hybrids. On the package with seeds there is always an explanation or a leaflet with recommendations is separately attached.
Pinching cucumbers in the open ground
At home, it is better to grow cucumbers on a trellis or a special grid. For beginners gardeners, it is very important to know whether to pinch or not. On vertically arranged shoots, the need to perform the reception is better visible.
Rules for the formation of a bush of cucumbers:
The formation of 7-8 leaves on the central shoot without the appearance of lateral shoots indicates the need for pinching. Otherwise, the harvest will be minimal, and it is possible that the fruits will be bitter.
We examine the bush and determine the floor of the flowers. Male flowers are mainly located on the central shoot of 5-7 pieces. The peduncle is thin (empty). Female flowers, depending on the variety, are located on the lateral and central shoots. Mostly female flowers are single or 2-3 in the group. They differ from men in miniature ovary (thickening) at the peduncle.
On the central shoot, empty flowers are removed and the top is nipped at 1.0-1.5 cm. Lateral branching will begin, on the shoots of which there are female flowers that form the crop.
Lateral shoots on the bush leave 2-3-4 no more. The rest are deleted. In addition, if stepsons have formed in the bosom of the leaf, they are also removed.
Pinch the side shoots on a 4-5 leaf so that all the nutrients are used to form the fruit. If you do not pinch them, the bush will occupy a large area with vegetative shoots. On the left shoots, the main crop is formed. On the bush, all diseased leaves affected by pests are removed.
If there are a lot of lateral shoots, it is quite possible that the variety or hybrid belongs to the early group and does not need pinching. In this case, the thickened bush is clarified, that is, individual shoots growing inside the bush or leaves that greatly obscure the shoots with the second or third layer are removed.
At the bottom of the bush, at the level of the first 2-3 true leaves, all side shoots are removed, for better development of the root system of the culture.
Formation of bush and self-pollinated zucchini:
Zucchini, zucchini-zucchini, squash squash and self-pollinated varieties do not need pinching. They form fruits on the central stem.
Zucchini greenery is removed with a fruit length of 10-15 cm. It is better to clean 2 times a week. Frequent eating of fruits stimulates the formation of new ovaries. Squash is ready for harvesting at the age of 7-8 days.
If the bushes are overgrown and huge leaves obscure the access of the sun's rays and insects to pollinators (in the case of pollinated varieties), then during the fruiting period, 2-3 leaves can be removed at the places of crop formation. This technique will simultaneously protect the plant from the appearance of rot, which develops when excessively abundant watering in a humid microclimate of the bush.
The formation of climbing zucchini:
In the climbing varieties of zucchini, pinch the top over 4-6 sheets. Some gardeners suggest removing part of the main stem at the beginning of budding. By this period, the zucchini already has several side shoots. Usually, 3-4 are left with a length of 60-70 cm. The main crop is formed on the side shoots and in general the bush will occupy a smaller area, overgrown with lashes.
Features pinching pumpkin
Like pumpkin squash, there are 2 types of aerial mass formation - bush and climbing. Long lashes of plants occupy an area of several meters, so they are practically not planted in cultivation, but only in separate sunny places.
The formation of climbing pumpkin varieties
In the phase of 3-5 leaves, the culture forms embryonic flowers and stepsons. While the lashes are short and not intertwined, carefully guide their growth in one direction. You can even pin to the soil with a wooden flyer, but freely, without pinching the whip. It is better to leave such lashes 2-4 no more. Remove all the rest and sprinkle the wound surface with ash.
We pinch the remaining lashes upon reaching 1.0-1.5 m. This provokes the best growth of lateral shoots, on which the bulk of the fruit is formed. To make them larger, leave 1-2 ovaries on each lash, sometimes 3-4 and with their normal development, remove 1-2 extra ones. We leave a greater number of ovaries in case of fetal disease in its infancy.
Throughout the growing season, we monitor the formation of new lateral lashes and do not form flowers - we delete. The entire period of growth and development of lashes continue pinching the tops. It is possible to carry out pinching, that is, remove all axillary vegetative shoots with a length of not more than 5 cm.
In August, we form a crop. On the lashes we leave the desired number of fruits for ripening. Better 1-3-4 fruits on the whole bush, no more. We remove all excess young pumpkins and use them fresh for cereals, baking in the oven and other dishes. Remove ripe fruits before the onset of cold weather. Store in a warm, dry place. The kitchen is a great place to store them.
Formation of bush pumpkin varieties
Shrub forms also need to be pinched and removed excess sterile lateral shoots to avoid thickening. An important event in bush pumpkin species is the normalization of the crop. Excess fruits (especially late formed ones) have low keeping quality and taste, therefore they are removed. Fruits formed in the early period are left for ripening.
