When the pear tree enters the fruiting stage, its production is large, the apex grows vigorously, and it is easy to form a strong external weak, strong upper and lower, and many peripheral branches. At this time, it is necessary to shape the tree, enlarge the canopy and promote a large number of fruit branches, control the periphery to prevent it from growing too much, and ensure the apex advantage of outward extension, and require multiple short branches in the hall to increase the angle and open. The skeleton controls the canopy to rise too fast, so that the inner branch of the church gets a sufficient nutrient. Through artificial cultivation, the canopy of the whole pear tree becomes a high-yielding tree shape of "big branches, bright branches, and small branches." In the winter pruning, for the previous years, the "long-light shearing" method was adopted. This period should be gradually modified or omitted under the premise of ensuring the output, so as to avoid the appearance of large and small, externally squeezed, and guilty. Branches are attenuated. When pruning, the branches of the diseased insects, dry branches, thin branches, overly branches, and overlapping branches are cut off. For drooping branches, they should be cut at their strong branches to raise the branches. Angle to make it grow well. The long branches of the thinner parts can be short-cut, artificially cultivated into the resulting branch group, and the site is based on the open space. For a well-developed new one, choose one branch every 15~18 cm. If the variety belongs to a species with weak growth potential, the first branch should leave 3~4 buds short, if it is a strong variety , can leave 6 to 8 buds short cut. In the next year after the short cut, a new crop will be drawn in the lower part, and the new one will be topped in the summer to promote its robust growth and cultivation into a result. When the lower part is likely to become short branches during winter pruning, it should be short-cut on its short fruit branches. If they are all intermediate branches, leave a long branch on the middle branch and 2 to 3 long branches. If they are all growing branches, leave the lowermost growth branch and keep 4 to 6 buds for short cuts. deal with. Pear trees with normal pruning growth should be lightly cut. Generally, the small and medium branches with too drooping apex should be properly retracted, and the outer branches should be thinned. The length of 20 to 30 cm should be cut off. Branches of 45 to 50 centimeters long should be shortened by 1/3. With the growth of shoots, the enlargement of the canopy should be appropriately shortened according to the growth of the extension branches on the main branch each year. Generally, about 40 cm can be cut. The center leader branch reaches a certain height to cut off the upright part of the center leader branch, so that the branches at the top of the branch can grow and grow to enhance the ability to firm. After the pruning is completed, the fruit trees of the whole orchard should be disinfected in time according to the mouth and the large cut to prevent the after-effects. At this time, 1000 times of carbendazim solution or sulphur mixture can be sprayed 1-2 times. Disclaimer: Some articles on this website are transferred from the Internet.
