【摘要】 本文基于2015年-2019年全国农户农药购买和使用情况的抽样调查,对长江流域5省16个县(市、区)冬小麦用药情况8个指标的监测数据进行了统计分析。结果表明,以农药毒性指数评价小麦农药减量增效好于其他指标,该指标可为定量、合理评估小麦科学安全使用农药提供依据,并可作为政府决策、技术部门指导小麦生产用药和减量使用的参考。更多还原

【Abstract】 Based on the sampling survey of farmers’ pesticide purchase and use in China from 2015 to 2019, the monitoring data of eight indicators of winter wheat drug use in 16 counties(cities, districts) of five provinces in the Yangtze River Basin were statistically analyzed. The results showed that the toxicity index was better than other indexes in evaluating the reduction and efficiency of wheat pesticides. This index can provide a basis for quantitative and reasonable evaluation of the scientific and safe use of pesticides in wheat, and can be used as a reference for government decision-making and technical departments to guide the use of pesticides in wheat production.更多还原
