Pear Autumn Management Technology
According to the law of the growth of fruit trees, comprehensive management of this period should be carried out. On the basis of ensuring fruit harvest this year, it will lay a good foundation for the normal growth and development of pear trees in the next year and ensuring a good harvest. To this end, it is necessary to strengthen the field management of pear fields in the fall. Mainly do the following five tasks: In the past several years, through the observation of the characteristics of the planted pear varieties, the varieties with high performance, such as new high, longevity, and autumn water, have to be highly connected, changed varieties, and improved in quality. Budding can be carried out from the beginning of September to the beginning of October, and branching can be carried out after mid-October. Longer yields can quickly restore production, while the original old varieties in the tree can also have some production. Usually 3 years old, 15 or more buds; 5 year old trees have more than 50 buds. If autumn grafting is not completed, it can be completed in February of the following year. Pear trees that are generally 2-3 years old when they are generally used for pulling branches are mainly used to pull main branches or extension branches of main branches, vice main branches, etc., 4-5-year-old trees mainly pull extension branches, side branches and second branch of main branches. . Because the autumn branches are soft and not easy to break, the shape is fast and the branches are flattened or headed downwards. After loosening them for some time, they will rebound upwards. The secondary branch is lower than the main branch, the side branch is lower than the secondary branch, and the other standing branches do not have to pull. Increase the use of organic fertilizer combined with economic fruit forest "double increase and decrease", timely application of organic fertilizer. It is best to fertilize the soil under the fertiliser or fertilize the layer of soil. The depth of the ditch is not less than 40 cm, width 30-40 cm, length depending on the size of the tree, generally 40 cm in 1-2 years, 60 cm in 3-4 years, 80 cm in 5-6 years, up to 6 years Meter. In the previous year, the ditch was dug on both sides of the tree, and in the next year, it was dug on the north and south sides of the tree and excavated outside the original fertilization ditch every year. The removal of weeds is dominated by artificial grasses, and weeding is minimized with chemical methods. The purpose of weeding is to prevent weeds from competing with fruit trees to reduce the number of grass seeds in the soil next year. After weeding, we must pay close attention to earthworms and nocturnal insects on the tree to eat leaves. If serious, we still need to prevent and control it. Pest control is still high during the fall, and is prone to damage by spider mites and pear nets. In addition, leaf-feeding pests such as mulberry caterpillars, moths, and other late-born larvae are susceptible to melasma, rosyleaf, and spotted deciduous disease on wet leaves. Therefore, after the harvest of pear fruit is still needed to control 1-2 times spraying, available Nisugang, cypermethrin, mancozeb or Baitai and other agents. At the same time, it is necessary to remove dead stems from pear trees and bring them out in a timely manner to reduce the number of overwintering bases for winter moths and other pests.
