Biological control method for orchard ecology

Abstract

Disclosed is the biological control method for orchard ecology, which integrates the techniques of utilizing natural enemy insects and biological pesticides, the insect hazard to the plants in the orchard can be controlled, the application of pesticide can be reduced substantially, the ecological environmental contamination to the orchard can be minimized.

Description

technical field

[0001] The invention relates to an ecological biological control method, in particular to an ecological biological control method for orchards. Background technique

[0002] The long growth cycle of fruit trees, single planting, and the cultivation and management of clear tillage orchards affect biodiversity and are not conducive to the protection of natural enemy insects, resulting in poor stability of the insect community structure in the orchard ecosystem, and the variety and quantity of insects are varied. The prevention and control of beneficial insects and the utilization of natural enemies have brought great difficulties. In the process of orchard ecological protection, most pests are treated by spraying chemical pesticides and other biological agents. Although they can effectively control them, they lead to pesticide residues in fruits, and at the same time, the number of beneficial insects in the orchard is also greatly reduced. However, the drug re...
