摘要
近年来,小麦田杂草危害逐年加重,防控难度增加,为了验证不同小麦田除草剂品种和除草技术模式的除草效果,掌握小麦田化学除草技术模式的应用现状,进行了不同麦田除草剂品种和技术模式的药效对比试验,并调研了长兴县农资市场的麦田除草剂销售情况和种植大户麦田化学除草技术模式的应用情况。结果表明,小麦田采用土壤封闭处理的化学除草效果优于茎叶处理,不同作用机理的除草剂品种合理混配使用和轮换使用,能提高杂草防除效果;在错过土壤封闭除草最佳时期或土壤封闭除草效果不理想的情况下,可在杂草基本出齐后采用茎叶处理技术防除;目前长兴县小麦种植大户田间化学除草主要以茎叶处理技术模式为主,应加大土壤封闭处理除草技术模式的培训和推广力度。
In recent years,the threat of weeds in wheat fields has been on the rise,presenting escalating challenges in prevention and control efforts.To assess the efficacy of various herbicides and operational research methods in wheat fields,and to understand the current application status of weed control technology models in wheat fields,the efficacy tests on different herbicide and operational research methods in wheat fields were carried out.Additionally,a survey was conducted on the sales of herbicides in wheat fields and the application of chemical weeding technology models in wheat fields among large-scale farmers in Changxing County.The results showed that soil-sealed treatment exhibited a relatively superior control effect on wheat field weeds compared to stem and leaf treatment.The adoption of the technical model involving soil-sealed chemical weeding,along with the reasonable mixing and rotation of herbicide varieties with different action mechanisms,proved effective in enhancing weed control.In instances where the opportunity for effective control was missed,or the soil-sealed control result was unsatisfactory,stem and leaf treatment technology can be used to control the weeds after the weeds had emerged.At present,large-scale wheat farmers in Changxing County predominantly rely on the stem and leaf treatment technology model for chemical weed control.However,efforts should be directed towards providing trainings on and promoting the adoption of the soil-sealed treatment technology model.
