Scientific pruning. If the canopy is tall or the branches are cross-cut, the adult trees should be moderately retracted and pruned after the winter leaves. Short-cutting is used as the main method, and the combination of shrinkage and combination is used to cut the dense branches, cross branches, long branches and dead branches. The branches are distributed reasonably and cut into reasonable trees. The wound caused by pruning should be applied to the wounded anti-corrosion film in time to protect the wound from healing tissue growth and prevent infection. Increase fertilizer and change soil. Persimmon trees are deep-rooted tree species, which should be expanded to change soil and increase fertilizer to make the tree strong. In the winter, the persimmon tree should be expanded to change the soil. When the topsoil is backfilled, the plant will apply 100-150 kg of soil or 50 kg of pig manure or 100-150 kg of mushroom soil or 1-1.5 kg of calcium, magnesium and phosphate fertilizers, and topsoil. After mixing, fill the lower layer, fill the surface with the topsoil in the garden, or deepen the soil, that is, apply organic fertilizer to the canopy drip line, and then turn it 20 cm deep in the rhizosphere. Thoroughly clear the garden. Winter pruning should completely remove the diseased fruit, diseased pedicle, dead branches and fallen leaves, and eliminate the source of wintering pests. Persimmon trees with heavy damage to scale insects should be sprayed with insecticides and tree guards before germination in winter to spring.
