Key points of summer management techniques for planting peach trees

First, do a good job of pruning in summer

1. Arrange the equipment of the main and side branches.

2. Remove the overgrown branches with branches in the inner chamber.

3. Non-branched fruiting branches of about 40m / 50cm can be twisted.

4. The inner chamber is relatively empty and lengthened, so the semi-oblique branch can be cut off so that it can be cultured into branch group.

II. Diseases and insect pests

1. Diamondback moth: pay close attention to the occurrence and control of the first generation of diamondback moth; choose 20% thiazuron 3 1500 times.

2. Red spider: use 73% EC to control mites 2000 times.

3. Perforation: the peak period of peach perforation occurs after entering Meiyu. It is hoped that fruit growers should do a good job in the prevention and control of the plum entry period and the middle period of Meiyu (the interval of the second medication is 10 Mel for 15 days). The choice of medicine is 1 Vera 2VL 200 zinc sulfate lime solution, or 65% Dysen zinc 500 times, or agricultural streptomycin 3000 times. 4. Red-necked longicorn beetles and peach leafminer: the observation of the two worms was strengthened in late June, the adults were artificially captured, the larvae were dug up, and the worms were blocked with 80% dichlorvos 30-fold solution in cotton. Peach leaf moth was controlled by 1500 times with 20% diflubenzuron 3.
