The reasons for the prosperity of the latest apple trees and their solutions

China has the largest apple planting area and output in the world, and apples are widely cultivated in China, but the phenomenon of flourishing and growing often occurs in the process of apple tree growth, which affects the yield and quality of quality and reduces the economic benefits of farmers. So what is the reason for the prosperity of apple trees? How to solve the problem? Let's have a look with the editor.

I. reasons for prosperity and growth

1. Improper management

Many in planting due to the lack of management technology, in order to make fruit trees blossom and bear fruit, often blind watering and fertilization, do not understand the ring peeling or spraying control, so often to fruit trees to grow.

2. Improper pruning

Only pay attention to winter when pruning, pruning only once a year, once pruning is too heavy, so it leads to fruit trees flourishing and growing.

3. Partial application of nitrogen fertilizer

Plant growth is inseparable from nitrogen fertilizer, nitrogen fertilizer can promote plant growth, many fruit growers in order to accelerate the growth of fruit trees, partial application of nitrogen fertilizer, less for other fertilizers, resulting in plant growth.

4. The number of results is too small

The fruit number of the fruit tree is too small to achieve the purpose of pressing the crown with the fruit, and the nutrient supply of the plant far exceeds the needs of the fruit, so the excess nutrition is absorbed by the branches of the plant, resulting in vigorous growth.

II. Solutions

1. Strengthen management

Fertilization should be carried out according to different growth stages. Pay attention to the amount of nitrogen fertilizer and apply more farm manure or organic fertilizer, which can increase a variety of nutrients for plant growth. In the crown expansion, comprehensive and reasonable management technology is adopted to make it more branched, and flower formation measures such as long release, ring carving, branch drawing, ring peeling and so on are adopted to form a certain number of flower buds to achieve the purpose of crown pressure and control growth.

2. Timely pruning

In pruning, we should pay attention to the winter pruning to change the adjustment of the four seasons, winter pruning should not be overweight, mainly long and sparse branches, neither weak nor short. In summer pruning, it is necessary to pull branches and carve buds or peel around the long branches. For young trees with exuberant growth, they can be coring when the new shoots grow to 50 cm in May, so as to make them more branched and achieve the role of controlling prosperity. When the plant growth is exuberant, the effect of controlling growth is more obvious by girdling at the base.
