The fertilization of the litchi fruit tree is divided into two main stages in the annual cycle. One is the fruit ripening before and after the harvest to the autumn shoot, and the result of the mother branch. At this stage, the nutrients are consumed by the fruit, so as to ensure the restoration of the tree as soon as possible. Normally withdrawing the autumn shoots, it is generally required to apply a quick-acting fertilizer before harvesting the fruit. After each extraction of the autumn shoots, 1 to 2 times of fertilizer should be applied to make the strong autumn shoots. During the attack period, quick-acting nitrogen, phosphorus and potassium fertilizers can be applied. However, after the last autumn shoot turns green, the soil fertilization should not be avoided. It is also forbidden to apply fertilizer to the farmer too early in October-December. Otherwise, the winter shoots will be drawn out. It is more reasonable to apply farmyard manure in January. After each new shoot leaves turn green, foliar fertilizer (such as complex nucleotides) can be sprayed to make the branches and leaves more robust. The other stage is flowering and fruiting period. It should pay attention to rational fertilization to strengthen flowers and preserve fruit. During the flowering period, phosphorus and potassium fertilizers should be applied mainly, and nitrogen fertilizer should be applied to avoid the occurrence of “shooting†and spring shoots, affecting flowers. The quality of the cytokinin, such as litchi fruit, 15 days before flowering, can make the flower head strong and improve the quality of the flower; in the fruit setting period, especially in the late stage of fruit development, due to the rapid growth of pulp, it consumes a lot of nutrients, so that The tree is seriously deficient in nutrition, and timely supplementing the tree nutrients will play an important role in strengthening the fruit and reducing the fruit drop before harvest.
