Autumn is a key period for the management of cherry saplings. To this end, Cai Yuliang, a professor at the College of Horticulture of Northwest A&F University, suggested that the farmers should manage the cherry garden as follows: Fertilization Cai Yuliang pointed out that because the young cherry saplings grow faster and need more fertilizer, they need to carry out autumn topdressing in September. They can apply fruit tree special fertilizer + potassium sulfate mixed application, 0.5 kg per plant, and can be applied by diagonal radial strips. Fertilization. In addition, 0.3% potassium dihydrogen phosphate was added to each spray to perform foliar spray fertilizer to protect the late leaves. In late October, the base fertilizer was applied to the big cherry, and the organic fertilizers such as farmer's fertilizer were mainly applied. Each plant was fertilized by about 50 kilograms, 1.5 meters away from the trunk, and the deep ditch of about 0.4 meters was cast on both sides of the tree. Apply proper amount of water after each application. Cai Yuliang suggested that after fertilization in autumn, when the soil is not sticky, the whole garden will be ploughed once to increase soil permeability and promote root growth. Rare and dense, to ensure that the light cherry is light, and the young tree should be shaped mainly. In order to ensure the ventilation and light transmission of the whole tree, Cai Yuliang suggested that for some overlapping main branches or excessive erect branches on the main branches, the branches should be removed in time from the main trunk, and the erects on the main branches can not occupy the space. Lateral branches, appropriate short cuts, to promote new branches, forming a new result branch group. Pulling the branch opening angle, autumn picking the heart into the autumn, the thick branches with bad softening effect, carry out the autumn pull branch, during which the pull branch effect is better than the spring pull branch, which can make all the buds develop balanced, with less erect branches on the back. The back, sides, and front and back are uniform. In order to ensure the fullness of the branches, the last topping before and after the autumn equinox is beneficial to the safe wintering of the young tree branches. Prevention and control of pests and diseases The main pests and diseases in autumn include bridgeworms, canopy caterpillars and peach leaf miner moths, which can be targeted for prevention and control. Leaf perforation is the most important disease of cherries. It occurs mostly in autumn. It can spray 200 times Bordeaux mixture or spray 0.3~0.5 degree stone sulfur mixture to control the occurrence of diseases.
