| Abstract: In order to promote the reduction and synergism of pesticides, the sustainable management of diseases and insect pests, and ensure the quality and safety of agricultural products, agricultural production safety and agricultural ecological environment safety in Beijing, more than 20 core green prevention and control technologies commonly used in vegetable production in Beijing were summarized, including whole garden cleaning, non diseases and pests seedling raising, antepartum greenhouse and soil disinfection, comprehensive prevention and control during production, and after production vegetable residue harmless treatment to integrate different production methods and production links, covering before production, during production and after production, forming a whole process of green prevention and control technology system. A green prevention and control demonstration base was established to integrate, demonstrate and promote the green prevention and control technology in time. At present, the demonstration area is 2 200 hm2. In the green control base, the qualifi ed rate of pesticide residues detection of agricultural products was 100%, the utilization rate of green prevention and control technology was 100% and the proportion of specialized and unifi ed prevention and control was more than 80%. The average application times of pesticides were reduced by 5-13 times, the dosage of chemical pesticide was reduced by 27% - 42%, the control effect of disease and insect was improved by more than 20% and the income increased by more than 10% per 667 m2. |
