Young mango trees are fertilized 5-6 times a year, mainly topdressing, and the principle of "small amount and multiple times, diligent application and thin application" is adopted. According to the growth of young trees, two fertilizers are generally applied to one branch, that is, one fertilizer is applied when the branches are pulled out and the other fertilizer is applied after the leaves turn green. Fertilization amount is comprehensively considered by crown size and growth. Generally, 50 ~ 100g urea is applied to each plant. At the same time, apply 5~ 10 kg of organic fertilizer every spring to facilitate the growth of young trees.

Second, the pruning of young mango trees

After planting, attention should be paid to shaping and pruning young mango trees. Generally, the height of the stem is 50 cm, leaving 2~3 main branches, leaving 2~3 main branches on each main branch, and so on. After planting, the seedlings can be cultivated in a large area when the height is 60~70 cm, and 3~4 strong branches are left as main branches in appropriate positions, and then topped twice each time, and 2~3 growth-promoting branches are left as auxiliary main branches. After 2~3 years' management, the mango plant is as high as 1.5~ 1.8 m, the crown width is larger than 1.5 m, and the number of branches is 80~ 100 (the last tip).

Dwarf and close planting pruning young trees are generally carried out in the nursery or the year of planting. When the height is 40-50 cm, there are 3-5 main branches, and there is no central trunk. The main branches are evenly distributed around, and each main branch has 2-3 lateral branches. Then, when the main branch is 30-50 cm long, the core is picked to promote the second branch, 2 for each main branch, and so on. The overall purpose is to create conditions for early fruiting and high yield.

Third, water mango seedlings.

Generally, after young mango trees are planted, they should be watered with sufficient water, which depends on the local climate or soil conditions in the future. For example, in the spring drought season, pay attention to soil water loss and carry out irrigation.
