Generally, fertilization of litchi requires comprehensive consideration of local climate, variety, growth stage and growth, and then flexible fertilization.

First: base fertilizer

When applying base fertilizer, apply enough base fertilizer. The basic fertilizer mentioned here usually refers to the fertilizer applied for the first time when planting. You can use farm fertilizer and compound fertilizer as the basic fertilizer. The amount of farmhouse fertilizer applied per acre is about 6,000 kg, and the amount of compound fertilizer is about 100 kg, usually in the form of digging holes to fertilize.

Second: growth fertilizer

One month after applying basic fertilizer, if the litchi tree is not growing fast, then we can add about 50 kg of urea to the fruit tree to help the fruit tree restore its vigor, and then we apply phosphate fertilizer and potash fertilizer in an amount of 60 kg per mu. Before the litchi tree blooms, the growth fertilizer is applied 4 or 5 times a year. The amount of fertilizer can be determined by whether the fruit tree grows or not.

Third: Flower fertilizer

Litchi trees can use flower fertilizer when they are adults. The first fertilization was carried out half a month before the litchi tree bloomed. Most of the fertilizers used poultry manure and compound fertilizer. An acre of land required about 1,000 kg of fertilizer. In addition to manure and compound fertilizer, each litchi plant The tree can also add a little more boron fertilizer and zinc fertilizer. The second fertilization can be carried out when the flower bones are formed, because the flowering speed of the litchi tree is very fast, so you can apply more potassium fertilizer, and then add a little compound fertilizer as appropriate. As for the fertilization method, it can be sprayed. , This effect will be better.

Fourth: Fruit fertilizer

It's time for the results after the flowers have been thanked. Fertilization is also divided into two in the result period. The first fertilization can effectively preserve fruit, usually after one day of fruit sitting, you can spray foliar fertilizer on the fruit tree to achieve fruit preservation. Like the well-known zinc fertilizer, magnesium fertilizer, potassium fertilizer, etc. are all foliar fertilizers. The second time is the strong fruit period. When the litchi grows to the size of peanuts, it will start to apply strong fruit fertilizer. It is usually to use rotten farm manure and compound fertilizer after adding water and then watering, so as to help the fruit expand.

Fifth: curing fertilizer

Conservation fertilizer usually refers to a fertilizer applied after the litchi is picked, which can effectively prevent the premature aging of fruit trees, thereby increasing the yield of litchi. At the same time, it can also restrain the germination of fruit trees in winter, which is similar to the first application of base fertilizer. Most of the maintenance fertilizers use farm fertilizers and compound fertilizers. As for the way of fertilization, it is recommended that you open up the ditch to fertilize so that the nutrients of the fruit trees can be better stored and not easily volatilized. It can be fully utilized by the next spring.
