Flower and fruit suitable for retention The dry-week method is normal, the tree is intact, and the non-aging tree is used. According to the length of the trunk in the middle of the trunk, the number of fruits retained in the whole tree is determined. The formula is: the number of fruits per plant should be: 0.2 dry circumference and dry circumference. For example, the dry circumference of the middle part of the tree is 30 cm, and it is substituted into the above formula. The number of fruits per plant is 0.23030=180 (one fruit). In order to prevent accidental injury, an additional 10% insurance factor should be added, and the actual number of fruits per plant: 180+18=198 (fruit). The distance operation is easy to grasp. Red Fuji apples leave 1 fruit per 25 cm, strong trees and weak branches 25 to 30 cm to leave 1 fruit, and the fruit is evenly distributed. However, it is easy to stay in practice. It is more reasonable to use the dry-week method to determine the total load of the whole tree. Flower thinning program Sparse the tree first, then sparse the small tree; first weaken the tree, then thicken the tree; first sparse flowers, fruity extra trees, then sparse flowers, less fruit trees; first loose bones, then sparse branches . In a tree, first the upper part, then the lower part; first, the inner sputum, then the outer part; first dredge the flower bud flower and the deformed flower, then the top flower bud flower. In the operation, according to the order, step by step, to prevent leakage. Thinning flowers and thinning fruit According to the tree potential and the strong branches, the flowers and fruits are more reserved; the weak ones leave less flowers and fruits; the common trees have more flowers and fruits on the middle and long fruit branches; the short-branched trees have more branches and branches with a certain length of the branches. Flowers and fruits that do not leave the flower buds. Leave flowers under the appropriate load and leave the fruit in the bad weather conditions. There should be room for thinning and thinning of the fruit. Generally, the insurance factor is 15%-20% more than the appropriate amount. When the bag is set, the fruit is fixed, and the amount of fruit is 5% to 10% more than the appropriate amount. At the same time, the fruit should be selected, the center fruit, the large fruit, the terminal fruit, the drooping fruit, the evenly distributed fruit, and the fruit, the deformed fruit, the dense fruit, the small fruit or the fruit in the wrong direction should be removed to make the amount of fruit on the tree And quality. In principle, the principle of fruit retention on single plants and single branches is that the backbone branches are less left, and the auxiliary branches are more reserved; the strong branches are more reserved, the weak branches are less left; the inner sputum is less left, the periphery is more reserved; the backbone branches are less or not left; After the branch group is left behind, it will be retracted and updated later. After the whole tree load is adjusted, carefully review it to prevent leakage. The choice of fruit branches generally does not leave the "going fruit" (called inverted fruit), because this fruit is easily blown by the wind, its coloration is limited to the scorpion end, and the back of the fruit is easy to be micro-cracked. In addition, the fruit that grows on the fruit branches behind the backbone branches should be removed because of its weak development, low light, and poor coloration. The flowers and fruits of the buds of the buds are mostly excluded except for the small-year tree or the frozen tree. Disclaimer: Some articles on this website are transferred from the Internet.
