Summer fruit trees should be carefully

The author found that many fruit growers are convenient for bagging, while bagging aside some fruitless branches that are hindered by hand, and ask the reason why it is said that these branches are fruitless, light food is not dry, and shading, so the sparse. Some fruit growers think that summer thinning also includes juvenile fruit trees or early fruit trees. In the summer, juvenile fruit trees and early fruit trees are also thought to be unnecessary branches. Based on these phenomena, the author put forward his own views and discuss with you.

Summer is the period when fruit tree vegetative organ has the strongest assimilative function, most photosynthetic products, nutrient synthesis and storage at the same time. At this time, it is very important to allow enough foliage to occupy an effective space and produce a large number of photosynthetic products to meet the needs of fruit tree growth and storage of nutrients. In order to obtain high-quality fruit, it is necessary to properly remove some of the branches of mature fruit trees that seriously affect light, and to improve the light conditions inside fruit trees. However, if excessive overbridging is wrong. First, the percentage of fruit and fruit of the branches has been considered at the time of fruit setting. Although most of the fruit growers are fruits left by the distance method, it is necessary to leave sufficient leaves for fruit to synthesize the photosynthate. Second, 95% of the products that make up the fruit dry matter come from the photosynthesis of the leaves. Therefore, as long as the fruit trees on the opposite side can be seen at this time, the projection light spot under the noon crown can account for about 30%, so do not easily remove the leaves and branches on the fruit tree. In particular, juvenile fruit trees and early fruit trees should be under the premise of maintaining vigorous vegetative growth and expanding the canopy as soon as possible before considering the use of flower-stimulating means to carry out material accumulation and gradually transform from vegetative growth to reproductive growth. Therefore, young fruit trees and early fruit trees are best not to be sparse in the summer. Even if they are not removed, they must wait until the winter nutrient recirculation.

A branch is a firewood in the winter, but it is a green factory in the growing season, especially in summer. Here, to remind fruit farmers, we must be careful when cutting in the summer.
