How to carry out comprehensive prevention and control of tea plant pests and weeds?
The comprehensive prevention and control of diseases, weeds, and weeds in tea plants should be based on the overall ecological environment of the tea plantation, treating both the symptoms and the root causes. The principles of safety, rationality, efficiency, and economy should be followed in accordance with local conditions, and agricultural control, chemical control, biological control, and other The prevention and control measures are organically coordinated to control the pests in tea gardens to the following levels of economic loss, and ensure the high yield and quality of tea production. Implementation of comprehensive prevention and control of tea pests and weeds should be based on the goal of protecting the balance of insect communities in the tea garden ecosystem, focusing on the control of pests and weeds, allowing a small amount of harmful organisms to exist in tea gardens, and facilitating the promotion of ecosystems. The relative balance. The prevention and control measures should be based on agricultural prevention and control, apply biological control and physical prevention methods as much as possible, and supplement chemical prevention and control methods for comprehensive prevention and control. Its main contents include four aspects: improving the ecological environment of the tea plantation, giving play to the natural regulation and control capabilities of the tea plantation, strengthening the ecological regulation and control based on agricultural prevention and control, vigorously developing biological control, protecting and utilizing natural enemies' resources, rationally carrying out chemical control, and realizing the absence of tea Pollution production.
