How to do girdling and top dressing of Wangshu in summer

It's the right time to pull branches

Pulling branches, generally last year's branches or perennial branches have a series of small, medium and short branches, which are twisted and drooped from the base or fixed with plastic bags. The photosynthetic products can not return to the tree and the roots and can only accumulate on the top of each branch. If there is more accumulation in the bud, the conditions for the formation of flower buds are available.

Tewang tree should be girdled and cut

Wide girdling should be used for the initial fruiting tree and the special tree with a certain number of short and medium branches. Because of the wide-ring stripped cambium, a new cortex is formed. The bark is smooth, and the formation of the sieve tube will cause little harm to the tree. However, it is necessary to peel a tree and wrap it in newspaper immediately to avoid direct sunlight. There is no effect to prevent disease and cure insects

If there is fruit or not, worms are sick. Rotting disease destroys the garden, powdery mildew destroys the tender shoots and hardly blooms. Aphids destroy young shoots and leaves. The more vigorous the tree is, the more young shoots will be. The more tender shoots there are, the more aphids will be. The red and white spider destroys the leaves, the leaves are gone, and they cannot carry out photosynthesis. If there is no accumulation of photosynthetic products, how can they form flowers? The use of medicine before and after bagging is very important.

If there is no result, we will have to supplement phosphorus next year

For trees with large fruit-bearing capacity and weak tree vigor, bio-enzymes + high-phosphorus water-soluble fertilizer + mineral crystals (apply twice in ******). For non-harvest orchards, control fertilizer and water, and only apply high-phosphorus water-soluble fertilizer. Always keep an eye on the prevention and treatment of rot

The nutrient conversion period of fruit trees is about to come, that is, when the green and yellow are not connected, the tree is the weakest. Rotting bacteria are weak parasitic bacteria and will take the opportunity to infect. The laws of rot disease are infection in summer, latent in autumn, development in winter, and rotten skin in spring. Therefore, the nutrient transition period is the best time for pathogen infection. At this time, some preventive agents can be used to start with prevention.
