At present, the average temperature is at the highest and there is more rain weather. Young mango trees are in the growth stage of branch tip. The management aims to promote branch tip extraction and expand the crown. Results The tree was in the period before and after picking, which was mainly to pay attention to the early autumn shoot. At the same time, some cultivars who had not picked fruit should also pay attention to the preparation of the early autumn shoot, so that the second autumn shoot could be taken out in time to form a good parent branch of the next year.

fertilization

Choose to pick on nutrient fertilizer comprehensive function of new fertilizer, such not only can provide many elements required by the supply of mango growth (nitrogen, phosphorus and potassium), also can make up for the timely trace elements (calcium, magnesium, boron, iron, manganese and zinc fertilizer), mango deficiency disease prevention, plastic flow, trunk cracking necrosis in attack, accelerate recovery of trees.

The principle of fertilization is as follows: the trees with more and weaker results should be applied more, with nitrogen fertilizer as the main fertilizer combined with phosphate potash fertilizer, and 1kg menomba 20-5-7 can be applied per plant; Results Fewer and more prosperous trees should be applied with phosphorus and potash fertilizer as the main fertilizer, and with appropriate minimum nitrogen application, 0.5 kg Menomba 13-8-24 could be applied per plant. About 3-5 days after fruit picking is the best time for fertilization (fertilization first, pruning later, and pruning after fruit picking for 7-10 days). Digging ditching for fertilization or sprinkling after fertilization after rain can be selected to make up water in a timely manner to improve root activity, accelerate the absorption and application of fertilizers and promote tree recovery in a timely manner.

Trim the branches at the right time

Immediately after harvesting, mainly to remove the disordered branches, overdense branches, pathogenic and insect branches and dead branches. Hainan mango blossoms and bears fruit by the top bud of autumn shoot. Most fruits hang on the surface layer of tree crown, only a few bear fruit on the inner bore branch, and very few bear fruit on stem and flower. Therefore, the surface layer of the tree crown should be lightly pruned to ensure the number of fruiting branches, and the internal bore branches should be heavily pruned to ensure the ventilation of the tree body, which is conducive to the occurrence of fewer diseases.

Water management

Currently in the rain season, low-lying orchards should pay attention to do a good job of drainage work.

Pest control

4--5 cm for the control of noctuid moth, thrips, anthrax, can be treated 600 times + charcoal cleaning 800 times;Severe occurrence of thrips occurred 600 times with Gigantean.Leaf cicada, aphid, wax cicada, scale insect and so on can be used 4000 times plus 3.2% avium 10ml spray kill.Bituminous coal disease is mainly controlled by preventing the occurrence of leafhoppers and aphids.
