Field Management techniques of Litchi

Litchi is a common seasonal fruit in summer. It tastes sweet, juicy, tender and delicious. Many farmers have planted litchi. Good field management techniques can increase the yield of litchi. So, what are the field management techniques of litchi? Let's get to know it together.

1. Fertilization

Fertilization needs to be divided according to the growing period of litchi trees. first of all, we are divided into two large areas, namely, the young tree stage and the fruit stage. The litchi tree in the young tree stage is mainly to promote the development of branches and leaves, so we try our best to apply fertilizer many times in the whole young tree period, with an appropriate amount of fertilizer each time, and mainly nitrogen fertilizer. And appropriate use of compound fertilizer, potash fertilizer, phosphate fertilizer and a small amount of boron and zinc fertilizer, litchi fertilization in the fruiting stage needs to be subdivided into three small stages, the first stage is pre-flowering fertilizer, mainly nitrogen fertilizer, appropriate use of potash and phosphate fertilizer, the second is strong fruit fertilizer, mainly potash fertilizer, supplemented with phosphate fertilizer and nitrogen fertilizer, the third is post-fruit fertilizer, mainly nitrogen fertilizer, supplemented with other trace fertilizers.

2. Weeding

Weeding is also carried out according to the growth stage of litchi trees. Young litchi trees need to be weeded at least seven or eight times a year, which requires specific analysis according to the growth of weeds. This can promote the root development of litchi trees and reduce nutrient consumption, while adult litchi trees usually only need to carry out intermediate ploughing and weeding three or four times a year. Weeding is carried out before flowering, before and after fruit picking, as well as in autumn and winter, which can enhance soil permeability and promote root growth and nutrient absorption.

3. Watering

The root system of young litchi tree develops slowly, so it belongs to shallow root Zhu Wu. We only need watering when there is less rainfall and timely drainage when there is more water in the field. However, there are several points that need to be paid attention to in the watering and drainage of adult litchi trees. For example, when litchi leaves grow short of water, they should be watered. Secondly, watering should be carried out during flowering. Then the fruit is watered at the initial stage of fruit development, but in the later stage, water should be reduced as much as possible, because it needs to accumulate sugar, otherwise litchi will have no sweet taste, and finally, it will be drained in time in case of heavy rainfall, otherwise it will cause many common diseases of litchi.

4. Pruning

In fact, the pruning of litchi branches and leaves is also carried out in stages. For young fruit trees, we mainly prune some long and messy branches and leaves under the litchi trees to maintain the growth of litchi trees. At the initial stage, we mainly promote the growth of the main branches, but when they grow to a certain extent, we need appropriate pruning to promote the growth of lateral branches. On the other hand, the adult fruit trees need to be pruned according to the principles of keeping strong and weak, new and old, and getting sick, so that the yield of litchi can be increased to a certain extent.

5. Pollination

When planting litchi trees, we matched the pollination trees according to a certain proportion, but now many orchards often use artificial pollination in order to improve the success rate of pollination of litchi. For example, bee colony rearing is carried out during the flowering period of litchi, followed by artificial pollen collection, and then artificial pollination is carried out by using sticking method, stripping method and spraying method. The success rate of pollination has increased, which means that the yield of litchi has also increased.

6. Disease prevention

There are many diseases and insect pests in litchi, such as anthracnose, downy mildew, leaf blight, fruit cracking, blight, litchi bug, inchworm, longicorn beetle, thrips, borer and scale pests.

The above is a brief introduction of litchi field management technology, I hope I can help you!
