How to increase the yield of Litchi

The taste of litchi is very good. I remember that when I was in primary school, there was a text in the Chinese textbook describing litchi. The editor also fell in love with eating litchi at that time, thinking that it was exquisitely carved like a beauty who had just come out of the bath. At the same time, there is also a well-known allusion, once riding the concubine of the world of mortals to laugh, no one knows that it is litchi. So it shows that litchi is very popular, even the emperor's concubines like to eat, but don't be greedy, you will get angry if you eat too much. So today let's learn how to increase the yield of litchi.

1. Pollination method

Litchi can be pollinated in two ways, one is pollinated by insects, and the other is artificial pollination. Sometimes there are errors in the pollination of natural insects, resulting in reduced production, so we sometimes put enough bees to pollinate in the litchi orchard, at least to ensure that most flowers can be pollinated. The method of artificial pollination can be further refined, including de-pollination method, sticking method and manual picking method. Here we mainly talk about the sticking method, which mainly drags the division of male flowers with wet towels or cloth and then rinses the stained flowers with water and finally sprays them on the female flowers.

2. Fruit protection technology

We generally carry out fruit protection through drugs. Generally, fruit protection is divided into flowering and post-flowering. When the flowering period is 10 to 15 days, we need to spray fruit-protecting agents on female flowers (specific agents can be consulted), which is helpful to improve the probability of fruit-setting. After the flowers have faded, they need to be sprayed once in Jingxing. If they are not sprayed, there will also be a lot of fruit drop in the fruit that has already been located, so it is mainly to ensure the fruiting rate.

3. Shaping and pruning

The shaping and pruning of litchi is generally divided into three stages. the first stage is when it is still a seedling, which is mainly to make the litchi tree grow up and only need it to open to a certain extent. therefore, the lower part of the branches that are not called messy will be cut off, and the branches and leaves that do not grow very well will be cut off at the same time, and finally the places where they are too luxuriant need to be thinned. The second stage is the fruit of litchi trees, we are mainly to prevent branches and leaves from growing too long, block the sun, resulting in lack of light, so as far as possible to ensure that there are certain gaps. The third stage is after fruit harvesting, sometimes some branches and leaves will be damaged during harvest, so we have to remove the already damaged branches and leaves, followed by cutting off some branches with poor fruit rate and keeping the best branches. in this way, it will grow new and possibly better branches.

4. Planting density

In general, we will not let litchi trees grow very tall, so they all develop horizontally, that is, the spacing of each plant must be scientific, otherwise there will be problems such as lack of light, lack of supply, and so on. Therefore, the best density of litchi planting is at least four meters or five meters apart. Only by planting at this density can high yield be achieved and the quality of litchi will be improved.

5. Disease control

The main diseases of litchi are frost Phytophthora and anthracnose; pests include bugs, stem borer, inchworm, caterpillar, and so on. The most basic control method is to clean the garden once a year after the litchi is harvested, cut off the diseased or withered branches and leaves, remove all the weeds and other weeds in the garden, and finally spray a layer of chemicals to protect them, so as to prevent diseases in the coming year. If these diseases and insect pests occur during the result period, they should be treated with drugs according to different symptoms.

The growing environment of litchi is generally a relatively warm area, and there is a large area of litchi planting in Guangzhou, China, so the planting environment of litchi is also a crucial factor. The above is the pro-agricultural network to teach you how to improve the yield of litchi, of course, there are more than these, there are many, so if you want to know more information, please continue to follow us.
