The Latest Field Management Techniques and Methods Tutorial for Zucchini
Zucchini is an annual vining herbaceous plant, and in some parts of our country it is also called fugua. 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 relieving 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 together!
1. Water and Fertilizer Management
Zucchini is suited to growing in moist plots, so during cultivation sufficient water must be ensured. First, about one week after zucchini is transplanted, the seedling-establishing water should be applied well, and this should be done together with topdressing. The fertilizer is mainly urea or farmyard manure. Before fruit set, water application should be controlled to promote the development of the plant's root system and improve the rate of stable fruit set. After the first fruit has set, topdressing should be applied again, mainly with quick-acting nitrogen fertilizer, with the amount controlled at about 15kg/mu, to ensure the subsequent fruit set. 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. When the temperature is too low, attention should be paid to keeping warm and raising the temperature to prevent zucchini from frost damage. Usually, before the seedlings recover from transplanting, the interior should be kept closed, with the temperature controlled at around 28 degrees, and the nighttime temperature also needs to be kept at around 14 degrees. If sudden weather changes cause the temperature to drop suddenly, straw should be covered in time for insulation. After the seedlings have successfully recovered, field ventilation should be strengthened and the temperature appropriately lowered, with the daytime temperature controlled at around 22 degrees and the leaf temperature at around 12. This creates a good environment for the growth of zucchini.
3. Artificial Pollination
The natural pollination and flowering rate of zucchini is relatively low, so artificial pollination should be carried out during the early flowering period 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 male stamen. Then smear the stamen onto the stigma. Normally, one male flower can pollinate about 5 female flowers. Then use a brush dipped in ethephon to smear it on the flower stalk of the female flower. During artificial pollination, attention should be paid to thinning flowers and fruits properly. No more than one fruit should be kept in a 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 air and light penetration, increase humidity, and raise the probability of pests and diseases. Therefore, timely leaf removal is very important. We should decide based on the growth condition of the zucchini. Plants with vigorous growth and abundant branches and leaves should have more leaves removed. Conversely, fewer should be removed. The main purpose is to ensure sufficient air and light penetration in the field. Also pay attention to the method of leaf removal, and try to remove only the leaf without moving the petiole, so as to avoid wounds on the petiole and plant, as injuries to the stem 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.
