Everyone knows that you need to trim the leaves of fruit trees in spring and autumn. Why use garden tools to trim the leaves of fruit trees? Purpose and effect: The canopy of the fruit tree expands with the increase of tree age, and there are too many branches and leaves, which will inevitably lead to the consequences of dense inner space, premature senescence, serious age, and reduced fruit yield and quality. Prompt 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, the branches and leaves of each part of the canopy are densely adjusted, the distribution direction and the leaf area coefficient are adjusted to maximize the effective photosynthetic area of ??the canopy.
??② Regulate growth and results. Make the vegetative growth normal but not grow too long; appropriate amount of flowers and fruit without weakening the tree vigor; at the same time, it can prevent the fruit tree from aging in advance and renew and regenerate in time.
??③ Adjust the composition ratio of branches. Short branches have a short growing period, and consume less and accumulate early, but have fewer leaves and lower total photosynthesis; vegetative branches have a longer growing period and consume more, but they also accumulate later. Different tree species and tree ages require corresponding and appropriate branch proportions in order to make the operation, distribution, consumption, and accumulation of nutrients in the tree in the annual growth cycle coordinated with normal growth and reproduction rhythms. This can be achieved by trimming
??④ Pruning can also balance the growth potential between the population plants and between the main branches on a plant, thereby achieving a balanced yield and easy management. In addition, pruning is also a means to make the above-ground and roots grow in harmony.
