淮北麦田天敌有何发生规律,如何保护利用天敌,怎样科学防治害虫?对此,安徽省萧县农技推广中心经多年研究,现已提出了解决的办法。该中心农业科研人员致力攻关的“麦田天敌预测及利用技术体系的研究”项目,着眼于整个麦田生态环境,摸清了麦田天敌种类、发生规律及影响因子,明确了天敌的利用指标和利用时期;筛选出了防治麦田害虫的高效、安全农药;组建了麦田天敌预测及利用技术体系。据该中心负责人介绍,保护利用麦田天敌,可减少化学农药的施用,促进生态系统的良性循环,有益提高农产
How to protect and utilize natural enemies and how to control pests scientifically? In this regard, the Agricultural Technology Extension Center of Xiaoxian County in Anhui Province has proposed a solution after many years of research. Focusing on the ecological environment of the whole wheat field, the project of researching and using natural enemies of wheat fields focused on the types, occurrence rules and influencing factors of natural enemies in wheat fields and clarified the utilization index of natural enemies and Utilization period; screened the wheat field pest control of highly efficient, safe pesticides; established natural enemies of wheat prediction and utilization technology system. According to the person in charge of the center, the protection and utilization of natural enemies in wheat fields can reduce the application of chemical pesticides, promote the virtuous circle of ecosystems, and improve the agricultural production
