How does the aging pear tree update and rejuvenate?
After many years of aging, pear trees have become old trees, weak tree branches, bald guilt, and peripheral results. Production has declined dramatically and quality has declined. Pear trees of this age should be renewed and rejuvenated in time to rejuvenate old trees, improve the quality of branches, buds, leaves and fruits, extend the lifespan of the trees, and allow the old trees to regain the red sunset. During the aging period, the pear tree's ability to absorb nutrients is poor, nutrient consumption is large, branches are generally old, pruning should be based on rejuvenation, adherence to the principle of updating, and pruning should be based on control and control; Focus on weight, light weight. 1. Transform the tree During the aging period, the central branch of the pear tree should continue to fall and retract and reduce the height of the tree. The layered tree can be compressed into a single layer of happy shape. Or compress the halves of the back of the second main branch of the hierarchical tree. Or replace the lower layer with the auxiliary support to form a single "convex" shape. Unstratified trees are transformed into delayed happy shapes. 2. Withdrawal of perennial old and weak branches It can be retrospectively updated before blocking, cutting lightly at the branches of 2 or 3 branches at the front of the trunk, blocking the water, pushing the superiority to the lower branches, and cutting the branches in the latter half. To increase new branches, restore growth potential. In order to carry out large-scale updates in different years, we must first twig branchlets, try to retreat as much as possible, update 1 to 2 large branches each year, and complete the update of the entire tree in 3 to 4 years. If a one-time big update is taken, it will be a one-time big retreat for all large branches and a new crown. In the process of large-scale updating, for all the large numbers of new shoots to be sent out, first select the new ones, open the angles and orientations, and use mid-year and short-term, promote growth, cultivate new canopies, and cultivate them with pull, pressure and pressure. Result sticks. 3. Branchlet updates On the basis of the renewal of the big branch, the twigs will be updated at the same time. Some of the new shoots that sprouted from the small updates were selected as new backbone shoots and some were cultivated into fruiting branches. For the general debilitating branch, leave the bud on the branch and the strong buds of the strong branch to retract, in order to promote the new branch. During winter cutting, flower buds should be kept in proportion and the load of the tree body should be reasonably controlled.
