Technology of strong Flower and Fruit Protection of Litchi

Litchi is a very delicious fruit, with a very beautiful nickname-Feizixiao, is a special fruit of our country. And there is a wide range of planting areas in China, with the growing market of litchi. Growers all want to increase the yield as much as possible, and the key technology to increase the yield is the strong flower and fruit protection of litchi. So the editor today brings you the strong flower and fruit protection technology of litchi, let's take a look at it!

1. Cultivate spikes of flowers

In the process of planting, it is necessary to strengthen the management of litchi fruit trees, cultivate healthy and sturdy fruiting mother branches, and improve the flowering and fruiting rate of litchi. When cultivating flower ears, we should take short and strong, sound and normal proportion as the direction, so as to lay the foundation for litchi wrapping. Therefore, we are in the management of seeds, the cultivation of strong spikes is essential, in the litchi panicle growth period should be properly sprayed with berberine and other agents to carry out strong flowers and fruits. However, the flower ear should not be too much, so as to prevent the number of fruit remaining in the later stage from being too large, affecting the normal growth of litchi and reducing the yield.

2. Regulating florescence

Litchi has strong ear growth ability and high flowering rate, but the number of female flowers is relatively small, and the flowering period is also several. However, because of the different varieties of litchi, its growth habits and growth stages are different. Therefore, we should properly control the growth and development of litchi trees by regulating the flowering stage of litchi. Increase the number of female flowers, reduce nutrition consumption, reduce culture costs, and promote the development of flowers and fruits. It can also prevent the environment from affecting the pollination and fertilization of litchi, improve the fruit setting rate, and achieve the purpose of strong flowers and fruit protection.

3. Artificial pollination

The female flower of litchi tree can develop into fruit only through the process of pollination, although litchi is a heterophytic fruit tree. However, the growth time of female flowers is different from that of male flowers, and usually blooms in batches, so if there is no artificial pollination, the success rate of natural pollination of litchi is very low. Therefore, we should do a good job of artificial pollination in the process of planting, which can be pollinated by bees, wind and other factors. Or promote the female and male flowers of litchi to bloom at the same time to provide good conditions for pollination and fertilization of litchi.

4. Ring cutting to protect fruit

Ring cutting is the most basic measure to protect litchi fruit, but it is generally used in fruit trees with strong growth, especially those whose fruit is not more than twice, the effect of ring cutting is very good. Therefore, it is not suitable for old trees and weak-growing trees, which begin to be cut around 10 days after the female flowers have withered. First of all, select the stout branches with a diameter of about 5-7 cm, and then cut around the branch ring, the ring cutting depth can reach the xylem of the branch, not too deep, otherwise it will lead to the death of the fruit tree. Reasonable ring cutting can concentrate nutrition on flowers and fruits and improve the rate of flowering and fruiting. However, the time and method of ring cutting vary according to the variety of litchi.

We also need to understand the physiological fruit drop of litchi trees, the rational use of growth regulators can be sprayed about two weeks after the fruit drop of female flowers, and then spray again every other week or so for about three times, which can reduce fruit drop and increase the amount of fruit hanging. However, we should pay attention to the growth regulators, should not be excessive, to prevent the vigorous growth of litchi, but affect the amount of flowers and fruits of litchi.
