Pruning of mango trees can be carried out throughout the growing season. (1) natural round crown, more coring, bud smearing, branch pulling and bending, less pruning. The main operations are as follows: fixing the stem at 50 ~ 70 cm, coring or cutting the top to promote branching; Leave 3 ~ 4 new shoots as main branches, and erase the rest; Tree culture, the main branch is 40 ~ 50 cm long, promoting lateral branches, leaving two lateral branches, cutting the top at 30 ~ 40 cm, promoting the third branch, and so on, forming a natural round-headed tree. (2) For the layered form of main branches, the main operations are as follows: fixing the stem height at 50-70cm, removing the core and promoting branches; Selecting the first layer of main branches, leaving one upright and strong branch as the central trunk, and pulling the other two branches to make them form 60-70 degrees with the central trunk and evenly distributed; When the central trunk grows from the first main branch to the height of 100 ~ 120 cm, topping cutting will promote the branch to form the second main branch, and so on, forming the third main branch, with the trunk controlled at 3 meters and the trunks of each layer staggered into a cross; Suitable for dry and prosperous varieties, such as Thai green husk, white tooth, red tooth, string awn and so on. Select side branches and leave them, and leave 3-4 buds on the first layer of main branches as side branches (secondary branches). The first lateral branch is 40-60 cm away from the central trunk and 20-25 cm between the lateral branches. Leave a side branch as the continuation main branch. When it grows to 40-50 cm away from the first layer of lateral branches, the second layer of lateral branches remains, and the second layer of main branches 1 ~. After the trunk branch is selected, the other branches that disturb the tree shape are cut off, but the natural branches on the central trunk can be kept as auxiliary branches at one time.
