Pruning is one of the key measures to ensure the fast-growing, early results, high yield and high quality of mango.
1. Pruning before flower bud differentiation Excludes dense branches, weak branches, diseased branches, crosses, overlapping and long branches, increasing the transparency of the crown and promoting flower bud differentiation. For plants that have grown too much and have not been fruitful for many years, the plants are inhibited by ring cutting ("Huahuawang No. 2" after ring cutting), wire and roots are cut to promote flower bud differentiation.
2. After the second physiological fruit drop (about 3-4 months), cut off the peduncle and branches that affect the fruit development, and remove the deformed fruit, the diseased fruit and the small abortive fruit; the branches that are not fruitful or have no fruiting results. It can be short-cut as appropriate, promotes the shoot, cultivates the mother branch of the next year, and increases the transparency of the canopy.
3. Pruning after fruit picking This is the key pruning period. After picking the fruit, the result will be shortened to 2-3 knots at the base of the tip. The diseased branches, over-closed, crossed, overlapping branches and weak branches in the canopy are eliminated. Branches and long branches that are depleted due to years of results should generally be cut off, but if the position is appropriate, or the canopy is weak, Short update, rejuvenation of the canopy. Whether shaping or trimming, it must be closely integrated with fertilization and pest control to achieve the desired results. For the wound caused by trimming, the oily soft solid "healing anti-corrosion film" is protected, preventing pests and diseases from invading and cracking the wound, and promoting the rapid growth and healing of the callus.
