Improve fertilization methods and strengthen soil management. Apply bio-organic fertilizer and compound fertilizer, whether it is circular or radial trenching, one is that there are more radial trenches (8-10); the second is that the circular trench should be long; the third is the depth of 30 cm . Make the fertilizer widely contact the absorbing roots of the fruit tree.
For soil management, it is necessary to plan the orchard once a year in spring to keep the live soil layer well aerated and prevent the root system from leading to the surface layer.
Apply enough base fertilizer in autumn to increase storage nutrients. It is necessary to fully understand that adequate storage of nutrients in fruit trees in winter is not only the basis for ensuring the robustness of the tree, but also the key to ensuring the high yield and quality of the next year's fruit. Early harvest of fruit trees such as big cherries, apricots, peaches, plums, walnuts, grapes, early and middle ripe pears, apples, etc., will complete the task of applying basal fertilizer in autumn in September. Chestnuts and late-maturing varieties of apples, pears, peaches and other fruit trees must rush to apply sufficient base fertilizer after harvesting in October. When moisture is good, base fertilizer can also be applied with the fruits after autumn.
Dredge the drainage system to prevent water accumulation in the orchard. In the orchard, plan the orchard and increase the height around the main trunk by 15-20 cm to form a ridged back shape to prevent water accumulation under the trees after heavy rain. The rows of fruit trees are formed into depressions 15-20 cm below the canopy. They can be watered smoothly in dry weather, and waterlogging can be drained smoothly after heavy rains.
Strengthen soil improvement and scientifically replant young trees. For fruit trees with rotten roots and dead, if the lower part is in heavy soil, large holes must be dug, and the middle and lower parts must be filled with organic matter such as topsoil, sand, weeds, and straw to create a loose living soil layer.
All fruit trees with rotten roots and dead have many harmful germs remaining underground. Replanting small fruit trees is not easy to survive, and secondly, even if they survive, they will not grow vigorously.
