How to fertilize litchi after fruit picking

Litchi is a kind of fruit that everyone likes to eat very much, and the planting area in our country is also very large. When planting litchi, fertilization is very important, and it is a key measure to meet the nutrition of litchi blossom and fruit. When we apply fertilizer, we should do a good job of fertilization according to the growth period of litchi. One of the most important things to pay attention to is after fruit harvest, so how to apply fertilizer after litchi fruit harvest? Let's take a look at it with the editor.

1. Fertilization method

The main fertilization method is soil application after fruit harvest in litchi. We should first dig an annular trench about 30 cm deep and 20 cm wide under the canopy of litchi trees. Then sprinkle the fertilizer directly into the ditch, and then cover the soil to avoid fertilizer volatilization. If there are conditions, then we can use bean bran, peanut bran and so on to make water and fertilizer, and soak it for about a month until it is fully mature and without any sour smell.

Before picking litchi fruit, we should also apply fertilizer once, combined with post-harvest heavy fertilization, the effect is very obvious. If the litchi tree has a large amount of fruit, or the tree is weak, then we should not only apply heavy fertilizer to the soil, but also spray an appropriate amount of foliar fertilizer after fruit picking. Foliar fertilizer is mainly composed of compound nucleotides, which is sprayed about three times, and the interval of each spraying is about 7 days. To promote the extraction of new shoots and the restoration of trees as soon as possible. Finally, when turning green, we should also pay attention to spraying again to promote the ripening of the fruiting mother branch.

2. Fertilizer application amount

When applying fertilizer, we should pay attention to controlling the amount of fertilizer applied, and we should adjust the actual amount of fertilizer according to the actual situation such as tree age, growth and hanging fruit. At the same time, it should be combined with the autumn shoot of fruit trees to cultivate their own soil fertility and so on. For example, if the annual output is around 80kg, then ammonium carbonate or urea about 2kg can be applied. With the right amount of peanut bran or dry fertilizer, but also pay attention to the application of a small amount of phosphorus and potassium fertilizer to ensure to meet the nutrition needed for its growth.

3. Points for attention

For example, when applying farm manure such as chicken manure or pig manure, we should first pay attention to adding an appropriate amount of lime or superphosphate to fully mature before it can be applied. In the application of peanut bran and other fertilizers, it is necessary to mix some carbofuran and other pesticides, which can not only prevent underground pests, but also avoid root burning. Finally, if the soil is mainly sandy soil, then it is necessary to appropriately increase the amount of organic fertilizer, improve soil properties, and improve the ability of soil water and fertilizer conservation.
