Objective and effect: The canopy of fruit trees expands with the growth of tree age, and there are too many branches and leaves, which will inevitably result in external dense inner space, premature tree decay, severe years and years, and fruit yield and quality. Timely and reasonable pruning can have the following effects
????1 Adjust the reasonable distribution of branches and leaves. That is, on the basis of plastic surgery, adjust the density, distribution direction and leaf area coefficient of the branches and leaves of each part of the crown to maximize the effective photosynthetic area of ??the crown.
????2 regulate growth and results. Make the vegetative growth normal without over-expanding; the right amount of flowering, firming without weakening the tree potential; at the same time, it can prevent the fruit trees from aging in advance and update and rejuvenate in time.
????3 Adjust the proportion of branches. The short branch growth period is short, the consumption is small and the accumulation is early, but the leaf is small and the total photosynthetic rate is low; the nutrient branch has a long growing period and consumes a lot, but it accumulates in the later stage. Different tree species and tree ages require corresponding and appropriate proportions of branches, so that the operation, distribution, consumption and accumulation of nutrients in the tree during the annual growth cycle can be coordinated according to the normal growth and reproductive rhythm. This can be achieved by pruning
????4 pruning can also balance the growth potential between the population of plants and the main branches of a plant, so as to achieve a balanced yield and easy management. In addition, pruning is also a means of coordinating the growth of the shoots with the roots.
