Which month is the best pruning for mango trees?
Mango trees are relatively tall as a whole, and it is easy to grow branches. If it is not pruned for a long time, it will flourish every few years, but this will lead to a decrease in mango yield and a decline in the quality of the whole mango fruit.
Therefore, we need to prune mango trees every year to better ensure the rapid growth, early fruiting and high and stable yield of mango. During normal planting, mango trees are pruned three times a year. First pruning time: spring, before flower bud differentiation; The second pruning time: in summer, before flower bud differentiation; Third pruning time: autumn, after fruit harvesting.
Therefore, mango trees will be pruned at harvest time, that is, in August and September, and large and dense branches should be pruned to weaken the top advantage of branches.
Pruning method of mango tree
When pruning mango trees, we must follow several principles, dense and light, heavy and light, bright but not empty inner rooms. Only in some places that are too dense, heavy pruning should be done.
1, first pruning
Spring is the time when mango trees blossom and bear fruit. After the fruit is set, the unfruitful branches are cut short to reduce the loss of nutrients and accelerate the development and growth of the fruit. The pruning amount in this period should not exceed 20% of the whole tree. Pruning principle is based on thinning, supplemented by short cutting.
2, the second pruning
Summer is the growth period and maturity period of fruits. This period is mainly to prune some fruitless branches to reduce the loss of nutrients, thus accelerating the development and growth of fruits.
We also need to cut off pedicels and branches that affect fruit development, as well as sparse and deformed fruits, pests and diseases and too small abortive fruits. After such pruning, it can better promote the germination of mango trees, cultivate the fruiting mother branches in the coming year, and also increase the light transmittance of the crown.
Step 3 Trim for the third time
The main season of mango market is summer, and after autumn, the harvest has basically been completed. Pruning fruit trees again after fruit picking can promote the appearance of autumn shoots.
In addition, after harvest, autumn shoots should be cultivated at least twice in order to make the annual output higher, and the last autumn shoot should not be later than165438+1early October. Therefore, autumn pruning should be completed in late August and early September.
Matters needing attention in pruning mango trees
1, pruning hierarchy
When pruning mango trees, the inner cavity should be bright and not empty, and the surface should be neat and layered, but all branches in the inner cavity can not be removed, otherwise it is not conducive to plant growth.
2. Optical scissors
When pruning mango trees, it is necessary to gently cut the middle and lower parts of the fruit trees and leave as many branches as possible, which is conducive to sprouting new buds and ensuring the annual output in the future.
3. Branch culture
In addition, attention should be paid to the cultivation of branches when pruning, which can increase the branching level and make the fruit yield and quality higher.
