Pear sapling is an important period in the whole growth period of pear trees. Doing a good job of winter shearing is the key to tree management. After many years of production practice, the measures for pruning ten pear trees were summarized. First, because the tree shaped to leave the skeleton. Most varieties of pears have low branching ability and have large differences in growth between individuals. When plastic branches are selected to retain the stem branches, the tree shape must be cultivated according to the projected growth state of the plants. It is not possible to insist on uniformity, so that the growth advantages of plants can be fully utilized to make them early. Molding, early results. Second, low-rise, low-crown layers. With the continuous expansion and popularization of low-density cultivation, the development trend of pear-shaped tree is low-dry, low-crown, low-grade, large angle, clear between layers, and the dry height is required to be within 50 centimeters, and the height of the tree crown is not more than 3.5 meters. The angle of the branch branches is 50-60 degrees, remove the upright or leggy branches between the layers, or level them up, cultivating into auxiliary feeding branches and opening the layers, which is conducive to ventilation and light transmission. Third, light and long cuts are fundamental. Pruning of pear saplings, in principle, to grasp the amount of pruning should be light to slow release mainly sparse cut as little as possible. The saplings are left with many shoots, the total growth is large, the canopy is enlarged rapidly, the molding is quick, the result is early, and the early high yield is easy to achieve. Fourth, to extend the branch suitable short cut. Every winter cut, the extension branch on the main side should be shortened so as to maintain the growth potential of the branch. The canopy expands rapidly and occupies the effective space to the utmost extent. When the short branches are cut, the buds are cut off to leave the buds. The new branches have a certain open angle. Fifth, the affiliation should be clearly identified. During winter cutting, it is necessary to reasonably control the growth potential of supplementary branches and branches, and the branches that affect the growth of the branches should be cut off, or they should be weakened by shrinking and shearing to weaken the weak branches. Through pruning, the main branch, the main branch and the lateral branch are staggered and evenly distributed. The growth potential of the same branch branch is the same, and the relationship between the main branch and the subordinate branch of different levels is distinct, forming a reasonable tree structure. Sixth, keep more support for early results. In order to quickly shape the pear saplings, it is necessary to make full use of the space of the stem branches and keep more auxiliary branches. For the auxiliary branches, we should adopt the method of slow-pulling branches and combine the summer shear to promote the flowering results and the competition branches. When the leggy branches have space, they must also be placed slowly and slowly to cultivate the result branches or auxiliary branches and increase the number of young trees. Seventh, culture branch group puts in contraction. In the sapling period, in order to ease the growth potential, the first result is to put the shrinking method to cultivate the result sticks; for the weakly individual varieties, the large and medium-sized sticks can also be cultivated using the first trimming and then rearing method. In the branch configuration should be mastered less on the more, more and more in the small, large and small, small foreign large, it is best not to choose to stand upright or drooping branches. Eight, the top advantage needs to be controlled. In order to prevent the phenomenon of strong and weak pears, it is necessary to control the apical dominance. For strong varieties, such as: Jinfeng, Paris, etc. can be used to change heads for the weak, weak generation, the following generations of methods, so that the central leadership to do a curved extension, lower tree height, weak on the branch Varieties such as early crisp, pear, etc. should be dry extension of the center of the branch to dry dry pruning instead of cutting dry trim, so that the formation of short-term results of the end of the apex, bent branches pumping branches to form a new center leading. Nine, the main branch angle should be opened. The branching angle of the pear tree is smaller, and the crown is rapidly expanded. To ease the growth potential and form flowers earlier, the main branch angle must be opened. Can be used to support, pull, hanging, outside the bud buds, back branches and other measures, so that the main branch base angle maintained at 55-60 degrees, the side branch angle is slightly larger than the main branch angle. X. Surgery is optional. According to the growth conditions of different young trees, pruning response, and results characteristics, different types of shoots should adopt methods such as ring cutting, scratching, twisting, and branching, as appropriate, so as to achieve slower growth, increased branches, vinegar buds, and flowering. The purpose of plastic surgery.
