In the winter shear of fruit trees, there are differences in the pruning methods of flower buds and buds. If the flower buds and the buds are indistinguishable from each other, they may be mistakenly cut, especially for trees that have produced phenomena of large and small size, and correctly identify flower buds. Leaf buds are particularly important. The incorrect identification of flower buds and leaf buds and the incompatibility of pruning methods not only affect the yield and quality of fruit products in the year, but also affect the quantity and quality of flower bud differentiation. The contradiction between size and year cannot be adjusted in time. Therefore, first look at the flower buds during winter cuts, and then pruning and trimming.
I. Identification of flower buds and leaf buds should be differentiated from the external morphology and internal structure of the buds. The flower buds are full of plums and buds, with a rounded top, a large scale and a bright, cohesive, hard-to-squeeze when squeezed. There are fewer hairs, darker colors, and prominent ridges. The neck slenderly curls to the side, and the leaf marks are prominently squatting. After peeling the scales, a small green ball is in the middle. The leaf buds are smaller, with a slender tip, small scales, loose cooing and dark coat. After peeling off the scales, there are several needle-shaped green tines in the middle.
Second, look at the flower pruning The purpose of flower pruning is to accurately determine the number and quality of flower buds, and make targeted adjustments to avoid the formation of size years. For trees that have grown up in size, they should be meticulously and reasonably pruned according to their strength. For large-year trees with more flowers and good shoot quality, more flower buds on some medium and long fruiting branches should be cut off to achieve the purpose of flower exchange, reduce the amount of fruit in the current year, and meet the nutrient requirements for fruit growth and flower bud formation. . In the year when the results of the small year are insufficient, the preservation of the flowers should be the main reason, even if the flowers are left, the output of the year will be ensured. However, for weak trees with more flowers, we must cut off some of the flower buds on the weak branches, leaving only the flower buds on the strong branches.
