When do you usually plant zucchini? With efficient field management technology!

Zucchini is an annual trailing herb, which is also called compound melon in some places in our country. Zucchini is rich in vitamin C, glucose and other nutrients, especially the content of calcium is very high, so when is zucchini generally planted? With efficient field management technology!

1. Planting time of zucchini

Zucchini is a cold-resistant and heat-resistant vegetable, so it can be sowed in spring or autumn, and the suitable temperature for growth is 20 / 25 ℃, so spring sowing in early May, autumn sowing in early September, early sowing too late, serious diseases and insect pests, not conducive to sprouting.

II. Field management technology of zucchini

1. Water and fertilizer management

Zucchini is suitable to live in moist land, so it is necessary to ensure sufficient water in planting. First, watering the seedlings about a week after planting zucchini, and fertilizing with topdressing. Urea or farm manure is the main fertilizer. Before sitting on melons, it is necessary to control the application of water, promote the development of plant roots, improve the rate of stable melons, and fertilize again after sitting on the first melon, mainly with available nitrogen fertilizer. The dosage should be controlled at about 15kg/ mu to ensure the subsequent sitting melon quantity. When the zucchini enters the peak growth period, it needs to be watered once a week and topdressing once every three weeks.

two。 Control temperature

The cold resistance of zucchini is not strong, when the temperature is too low, we should pay attention to heat preservation and increase temperature to prevent zucchini frost. Usually, before the seedlings slow down, the indoor should be closed, the temperature should be controlled at about 28 degrees, and the temperature at night should be kept at about 14 degrees. If there is a sudden change in the weather, resulting in a sudden drop in temperature, it is necessary to cover the forage in time, keep warm, and strengthen field ventilation after the seedlings are successfully slowed down. Properly reduce the temperature, the daytime temperature is controlled at about 22 degrees, and the leaf temperature is about 12 degrees.

3. Artificial pollination

The natural pollination rate of zucchini is relatively low, so artificial pollination should be carried out in the early flowering stage of zucchini to improve the pollination rate of zucchini. On the morning of the second flower, the male flowers are picked, then the Corolla is removed, the stamens are exposed, and then the stamens are smeared on the stigma. Under normal circumstances, a male flower can pollinate about 5 female flowers. Then in the use of ethephon is easy to smear on the stalk of female flowers, in artificial pollination should pay attention to do a good job of thinning flowers and fruits, leave no more than one melon in the axil, and remove the excess melons in time.

4. Pick leaves at the right time

With the growth of zucchini, the leaves of the plant will become more and more luxuriant, and if the leaves are not picked in time, it is easy to close the field, reduce the permeability, increase the humidity, and increase the incidence of diseases and insect pests, so it is very important to pick leaves at the right time. According to the growth of zucchini, plants with many branches and leaves should pick more leaves, on the contrary, they should be picked less, the main purpose is to ensure sufficient permeability in the field. And we should pay attention to the way of picking leaves, do not move the petiole as far as possible, avoid petiole plants from producing wounds, stem injuries are difficult to heal, pay attention to the weather of picking leaves, preferably on a continuous sunny day, so as to ensure wound healing and prevent the production of diseases and insect pests.

The above is the introduction of the planting time, planting methods and efficient field management techniques of zucchini. Farmers who plant zucchini can use this article as a reference.
