Fruit trees need to be strengthened after the fruits are harvested and before the winter. According to the practice of many years of production, it is very important to grasp six managements before the winter. Specific management content is as follows: First, foliar fertilizer. After the fruits are harvested, they are sprayed with 0.5-0.6% urea once every half month, and can also spray 0.2-0.4% of potassium dihydrogen phosphate or 0.3-0.5% ammonium phosphate to increase the photosynthetic capacity of the leaves. Second, autumn basal fertilizer. Usually after fruit picking until late October. The method is to dig an annular ditch around the root of the tree and then apply the fertilizer into the ditch and then cover the soil. Generally, 100-250 kg of fertilizer is applied to each fruit tree, and 1.5-2 kg of superphosphate and 0.5-0.79 kg of available nitrogen fertilizer are mixed. Third, pruning topping. After the fruit is harvested, it is pruned and pruned before winter shearing. The main content is to properly cut off some of the leggy branches in the later period or carry out toppings in order to control the growth of branches and promote lignification. Fourth, plough the garden. The autumn orchards are overgrown with weeds and have poor soil permeability. Therefore, after harvesting, the cultivators immediately weeded and weeded deeply. Within the canopy, the interior of the canopy should be turned slightly to prevent it from being wounded; deeper than the canopy expansion point, the depth is generally 40 to 50 cm, which enhances the permeability of the soil and is conducive to the retention of water and nutrients and the ability of the root system to absorb water and fertilizer. Fifth, autumn pruning: After the fruit trees are fallen, the diseased branches, dead branches, dense branches, and inaccessible branch branches will be cut off in time, which will reduce the amount of winter shear and lay the foundation for the growth of fruit trees next year. Six, remove the source of the disease. After deciduous fruit trees, their deciduous, residual fruits, weeds, and diseased branches are taken out of the orchard and burned or buried deeply to eliminate overwintering bacteria and insect sources. The fruit trees with insect pathways were found, and 50% of the dichlorvos emulsifiable concentrate could be sucked with cotton balls and filled into the tunnel and then blocked with mud.
