The management of fruit trees in autumn and winter is an important part of fruit tree management and a necessary measure to ensure good growth and results in the second year.
1. Fertilizer basal fertilizer is the basic fertilizer for fruit trees to supply nutrients for a long time in one year and must be applied. Usually based on delayed organic fertilizer, combined with phosphate fertilizer and a small amount of available nitrogen fertilizer, organic fertilizer and more use of human and animal manure, green manure, grass, straw, etc., Phosphate fertilizer commonly used superphosphate. The optimum time for applying base fertilizer is autumn, and the fruit should be harvested immediately after harvesting, which should be done sooner rather than later. Fertilization methods can be used ring fertilization fertilization, radiation trench fertilization, strip trench fertilization. Apply alternately every year.
Second, irrigation of fruit trees in the autumn after the base fertilizer, soil irrigation before filling the winter water.
Third, the white trunk of tree trunk coated with white can prevent freezing damage and prevent the trunk from overwintering. The trunk is painted white with lime water, plus appropriate salt and pig blood. A small amount of yellow mud can also be added.
Fourth, pruning fruit tree pruning, especially winter pruning is the main measure of fruit tree management, flexible use of "short, thin branches, shrinkage, dumping, broken branches, curved branches, support techniques, pull techniques" and other means. To achieve "tangible, intangible, invisible," so that the backbone of the fruit tree is stable and firm, branches suitable distribution. After years of cultivation, the fruit trees are trimmed, and care must be taken to preserve the extension of the stem branches and to trim the branches. To achieve the "dilute under the dense, yang dense, thin and dense outside," three-dimensional results. To solve the problem of ventilation and light transmission, cross-branches, overlapping branches, drooping branches, and pests and branches should be appropriately dissected and shrunk. Pruning of pruning natural trees at the end of many years must be taken into consideration in the transformation of trees, making full use of "supporting, pulling" and other means to open large branch angles, conducting appropriate branching and shearing, and focusing on ventilation, light transmission, and regeneration of branches and branches. Do not avoid too much shrubs, and turn big trees into small ones, causing “face injury†and “ring injury†in the center.
Fifth, pest control (1) combined with pruning, cut pests and branches. Timely removal of dead leaves on the tree, removing lashings, etc. Elimination of pests and wintering sites. Scratch the old cracked skin on the tree and burn it. (2) The disease on the fruit trees must be promptly scraped. After scraping, apply 843 rehabilitative agent, rot and so on to remove the lesions. (3) Lime-sulfur mixture has an annihilation prevention and control effect against a variety of fruit diseases and insect pests. Especially after the fruit trees are defoliated, when the branches are completely exposed, the “light-drying†medicine has a better control effect, and it can use its own brewed Baume 3 degrees. The lime sulfur mixture. Spraying should be done from top to bottom, from inside to outside, spray evenly, spray the whole plant.
