How to effectively prevent and control excessive winter growth in mango trees

Mango trees are highly prone to excessive growth in winter, which consumes the tree's nutrients, weakens tree vigor, directly affects the quality of winter dormancy of mango trees, prevents them from overwintering normally, and also threatens the yield of the coming year. So what should be done about excessive mango growth in winter? Let's take a look together.

1. Shoot control

Traditional methods for controlling excessive shoot growth mostly use girdling, shoot killing, and root pruning, and these measures cause considerable damage to tree vigor and greatly shorten the lifespan of the tree. However, practice has proven that using girdling technology combined with applying a new type of agent is extremely effective for preventing rampant shoot growth. The method is: in October to November, use a knife to girdle the smooth part of the mango tree trunk down to the xylem, then use a protectant to apply back and forth over the girdling cut, so that the agent enters the gaps. Once the agent enters the tree, it can disinfect and activate the tree's anions, causing it to transform from vegetative growth to reproductive growth. This can control excessive shoot growth, improve dormancy quality, and enable more flowering and fruit setting the following year.

2. Pruning

In winter, prune diseased and insect-damaged branches, weak branches, shaded branches, and drooping branches from the fruit tree, cut back some fruiting branches, and prune dense buds on fruiting branches. At the same time, burn the pruned branches in a centralized manner. If the wounds after pruning are not sealed in time, they will dry and crack, be exposed to pollution and the threat of pests and diseases, and cause tree vigor decline. Therefore, a healing agent can be applied to the pruning cuts to form a water-impermeable layer that is tough and clings tightly to the wood, protecting the wounds and the growth of wound tissue.

3. Fertilization

After mango harvest, attention should be paid to base fertilizer and sunlight. The base fertilizer should be mainly decomposed farmyard manure, reasonably combined with nitrogen-phosphorus compound fertilizer and applied in furrows, then covered with soil after fertilization. Base fertilizer should avoid the application of large amounts of nitrogen fertilizer to prevent a second round of excessive growth. Farmyard manure has a long-lasting effect and requires a relatively long time for transformation so that it can be absorbed by the root system, so it will not cause excessive growth of the fruit tree after fertilization.

4. Orchard cleaning

In winter orchard cleaning, remove weeds from the orchard, build terraces, deep plow the orchard to improve the soil, cover the tree disk with grass, whitewash the trunk, and use the winter slack time to accumulate organic fertilizer. Before closing the orchard in winter and before bud break in spring, spray fungicides and insecticides throughout the orchard, whitewash the trunk for cold protection. Through spraying, eliminate pests and diseases that overwinter on mango trees, with excellent effects such as suffocating sterilization and heat preservation and freeze protection.
