Integrated control technology of plant protection in peach orchard (ipm)
There are six core technologies of IPM in peach orchard: (1) agricultural control measures of diseases and insect pests in peach orchard. Cut off the branches and fruits of diseases and insect pests during winter cutting, centrally destroy, adjust the tree structure, improve the ventilation and light transmission conditions, and enhance the tree potential; (2) the technology of trapping and killing pests with frequency vibrating insecticidal lamps. One insecticidal lamp was installed in 3.3hm2 orchard and applied from the first ten days of April to the middle of October, which could play a good role in killing insects. (3) the technology of trapping and killing pests in sweet and sour pot. Since the middle of March, sweet and sour pots have been set up in the orchard to trap and kill the overwintering adults of peach leafminer. (4) the technique of sex attractant isotropy to control insect pests. Two sex attractants for peach leaf moth and pear heart borer were set up per mu in the orchard from April to October, and the attractants were changed every 30 days, which had a continuous insecticidal effect. (5) biological control techniques of insect pests. Planting alfalfa and white clover in orchard can significantly increase the number of parasitoids, ladybugs, lacewings and other natural enemies, and the release of Trichogramma has a certain control effect on small leaf moth. (6) pollution-free pesticide control techniques for diseases and insect pests. With the popularization and application of IPM technology, the average annual pesticide use in Taoyuan was reduced from 10 times to less than 7 times, and the pesticide use was reduced by more than 3 times. The reduction of pesticide dosage improved the fruit quality and enhanced its market competitiveness, and the comprehensive benefit increased by about 540 yuan per 667m2.
The implementation of IPM technology has completely broken the traditional pattern of relying on pesticides for pest control, and is of great significance to effectively improve the quality of Beijing peach and improve the orchard environment.

From 1998 to 1999, five lines with better performance were grafted in the high-tech experimental park and production park of Chashan base in 2000. After 3 years of character observation, 026 showed early fruit.
