What is the apple tree blossom?
What is the apple tree blossom? Please introduce a two-year-old or three-year-old branch with a string of flower buds on it. On the surface, it seems to be a strong branch, but it is not. If the bud is carved on an one-year-old branch, under the condition of good light condition, good leaf protection and scientific fertilization, it can also form a string of flower branches in the second year. Similarly, multi-loop cutting of an annual weak branch, promoting sprouting of a weak branch, and sprouting and turning of a slender weak branch, they can also form clusters of flower branches in the second year. Therefore, there is a difference between the strong and the weak in nature. In addition to being full of tissue, the annual strong branch is much thicker than the weak branch, the number of vessels in its xylem is much more than that of the weak branch, and the amount of water and inorganic nutrients in the soil is also more than that of the weak branch. Therefore, it is not suitable to retract the bouquet of flowers. The withdrawal itself is concentrated nutrition, once the nutrition is concentrated, the fruit table will grow a little bit, and as long as the shoot grows, it will consume more nutrients, accumulate less, and cannot become flowers. One-year-old weak branches such as slender, weak and prosperous branches, because they are thinner than prosperous branches, and the tissue is not full, the degree of Lignification is not high. As a result, the number of vessels in the xylem is much less than that in Wangzhi. If the buds are not retracted during pruning, all the buds are left, the nutrients are dispersed, and less nutrients are allocated to each bud, so the fruit is small. Therefore, it is necessary to withdraw from them, reduce the "population" and concentrate on nutrition in order to bear great fruit. Especially in some weak big trees, the whole tree is full of flowers, so it is necessary to retract the weak flower branches. When it comes to the retraction of the weak string of flower branches, to say in more detail, the position of the branch of the weak string of flowers is different, and the amount of retraction is different. Generally, those born under the back should be heavier, the ones on the back are lighter, and those on the back are lighter or not.
