Two instructions for pruning Li Shu

First, we must pay attention to plastic surgery at present, the production of more natural happy shape. Its shaping is similar to that of peach, so it must be grasped from the time of young tree, focusing on light cutting, long planting, thinning and deleting, pulling branches and opening main branches, so as to accelerate the formation of tree crown. In general, from July to August or winter pruning, long branches are released mainly by pulling branches, supporting branches, falling branches, other branches, taking branches and other methods from the first year after planting. Used to induce flowering and fruiting. Second, we must pay attention to pruning 1. Pruning time. Comprehensive pruning should be carried out in winter; the weak or over-dense and over-long branches on the fruiting basal branches can be properly cut off in spring during the flower bud expansion period of plum trees; in summer, the straight main branches, twisted shoots with large space, coring, short cutting, pulling branches, ring peeling and so on on the back of the main branches of the internal chamber should be treated in June. Cultivated into solid basal branches, those that are too dense should be sparse from the base. In autumn, the elongated branches of the upright backbone branches of young trees can be stretched, the corners of the branches can be opened, and the dorsal strong branches of the backbone branches can be flattened and cultured as fruiting basal branches before the shoot is completely Lignified around August. The empty branches, crossed branches and overlapping branches should be removed. 2. Pruning method. Plum trees mainly bear fruit with bouquet-shaped short fruit branches and short fruit branches. Pruning should adopt thinning and pruning system. In the juvenile period, the extension branches of the backbone branches should be cut lightly, the shrinking branches should be shrunk 1 to 4, and the branches should be shrunk for 3 or longer. With the increase of the tree age and the increase of the fruit, the cutting strength will gradually increase, so as to keep the balance between the fruit and the growth. For the current year's growing branches or long fruit branches on the backbone branches, all those that are too dense should be excluded, and the rest should be put long, not pruned or lightly pruned, as the base branches for future fruit. All in all, if farmers want to increase their own plum tree yield and income, high and stable yield, and obtain higher economic benefits, they must cultivate a certain number of fruit bases every year; pull out short fruit branches and bouquet-like fruit branches on them every time; blossom and bear fruit in the third year and after, and after five years of fruiting branches, they will be cut off from the base or stump to rotate and renew. Generally, the annual fruiting of the basal branch is more than 1 stroke 5, so that the tree has 3-5-year-old basal branch fruit each year, so that the adult tree can maintain the coordination of growth and fruit after entering the full fruit stage, so as to achieve the purpose of high yield, stable yield and efficiency.
