Winter persimmon garden strict management upgrade points

 

Plastic trimming: 1. Pruning in the sapling period. The main task of pruning in the sapling period is to cultivate the backbone branches, rapidly increase the degree of the branches, and enlarge the canopy. When pruning, pay attention to less sparse branches, appropriate multi-cutting, increase the amount of branches, combined with winter and summer shears, and can be used for picking branches. 2. Pruning of adult trees. For the production of trees, the main focus is on thinning, supplemented by short cuts, and appropriately retracted. The main method of thinning branches is to cut off the cross branches, overlapping branches, thin branches, densely squeezed branches, and diseased insects to improve the ventilation and light transmission conditions. Appropriate short cuts of main branches, side branches and extension branches at all levels to promote new branches. It is necessary to carry out moderate retraction and pruning after the winter leaves, using short shears as the main method, shrinking and combining methods, cutting off dense branches, cross branches, long branches and sick branches, so that the branches are distributed reasonably and cut into reasonable trees. 3. The wound caused by pruning should be coated with the callus anti-corrosion film in time to protect the wound from healing tissue growth and prevent the pathogen from infecting the wound.

 

  Prevention and control of pests and diseases: 1. In winter, the diseased fruit, diseased pedicle, dead branches, persimmon skin, skin and leaves should be completely removed to eliminate the source of wintering pests. 2. The trunk is painted white. The whitening of the trunk can kill the pests that overwinter in the bark seams on the one hand, and prevent the plants from being damaged by freezing on the other hand. 3. Before the deciduous winter to spring germination, spray the tree general + stone sulphur mixture to prevent pests and diseases, and reduce the harm in the coming year.
