I. 1 month management

1, plastic trimming

Prune too dense, too weak, twisted and disorderly tree buds and twigs to adjust the tree potential. In winter, it is mainly to transform the tree type, dwarf the crown and enhance the illumination of the crown.

Six, August-10 month management

The late stage has the greatest influence on fruit quality, and nitrogen control and ring cutting are adopted. In addition, the control of leaf miner, aphid, anthracnose, whitefly, rust mite and anthracnose is equivalent to the control of fruit drop and pests before harvest. Fruit drop before harvest is often accompanied by pests, brown rot and green mold, and some varieties have cracked fruit.
