Detailed Explanation of Zucchini Field Management Techniques
Zucchini is an annual vining herbaceous plant, also called fugua in some parts of our country. Zucchini is rich in vitamin C, glucose and various other nutrients, and its calcium content is especially high. Zucchini has effects such as moistening the lungs and stopping cough, and reducing swelling and dispersing nodules. It is cultivated in all parts of our country, and growing zucchini requires a correct management method, so how should zucchini be managed? Below, the editor brings you the field management techniques for zucchini, let's take a look!
1. Water and Fertilizer Management
Zucchini is suited to growing in moist plots, so sufficient water must be ensured during cultivation. First, about one week after zucchini transplanting, the seedling-setting water should be watered well, and this should be done together with topdressing; the fertilizer mainly uses urea or farmyard manure. Before fruit setting, water application should be controlled to promote the development of the plant roots and improve the rate of stable fruit setting. After the first fruit has set, topdressing should be done again, with quick-acting nitrogen fertilizer as the main fertilizer, keeping the amount at about 15kg/mu to ensure subsequent fruit setting. When zucchini enters the vigorous growth period, it needs to be watered once a week and topdressed about once every three weeks.
2. Temperature Control
Zucchini is not very cold-tolerant, so when the temperature is too low, attention should be paid to keeping and raising the temperature to prevent zucchini frost damage. Usually, before the seedlings recover from transplanting, the interior should be kept closed, with the temperature controlled at about 28 degrees, and the nighttime temperature should also be kept at about 14 degrees. If sudden weather changes cause the temperature to drop suddenly, grass material should be covered in time for insulation. After the seedlings successfully recover, field ventilation should be strengthened and the temperature appropriately lowered, with the daytime temperature controlled at about 22 degrees and the leaf temperature at about 12. This creates a good environment for the growth of zucchini.
3. Artificial Pollination
The natural pollination flowering rate of zucchini is relatively low, so artificial pollination should be carried out at the early flowering stage of zucchini to improve the pollination and fruit-setting rate of zucchini. On the morning of the day the second flower blooms, pick the male flower, then remove the corolla to expose the stamen. Then smear the stamen onto the stigma; under normal circumstances, one male flower can pollinate about 5 female flowers. Then use a brush dipped in ethephon to smear it on the pedicel of the female flower. During artificial pollination, attention should be paid to thinning flowers and fruits, with no more than one fruit retained per leaf axil, and excess fruits should be removed in time.
4. Timely Leaf Removal
As zucchini grows, the plant's leaves also become more and more luxuriant. If leaves are not removed in time, it is easy to cause field closure, reduce permeability, increase humidity, and increase the probability of pests and diseases. Therefore, timely leaf removal is very important. We should decide according to the growth condition of zucchini; plants with vigorous growth and many branches and leaves should have more leaves removed. Conversely, fewer should be removed, with the main purpose being to ensure sufficient permeability in the field. Also pay attention to the method of leaf removal, trying to remove only the leaf without moving the petiole, to avoid wounds on the petiole and plant, as stem injuries are difficult to heal. Pay attention to the weather when removing leaves; it is best to have consecutive sunny days, which can ensure wound healing and prevent pests and diseases.
The above is a brief introduction to zucchini field management techniques. Of course, the primary management work is certainly pest and disease control. However, because there are very many types of pests and diseases, and zucchini also has several common pests and diseases, our website also has articles specifically introducing the common diseases of zucchini and their control methods, and interested friends can take a look! That is all for today's introduction. This article is for reference only. Thank you everyone for reading and supporting.
