不同药械喷施33%氟噻·吡酰·呋SC防控小麦田杂草的效果

Control efficacy of diflufenican·flufenacet·flurtamone 33%SC by different plant protection equipment against weeds in wheat field

为进一步优化麦田杂草防控器械使用技术,2022年选用多旋翼植保无人机、自走式喷杆喷雾机、担架式植保机、背负式电动喷雾器喷施土壤封闭除草剂33%氟噻·吡酰·呋SC,比较防控小麦田杂草的效果和作业效率。结果表明:药后30、100 d,4种施药器械处理阔叶杂草的防效分别为96.94%~98.98%、91.84%~95.92%,多旋翼植保无人机、自走式喷杆喷雾机和背负式电动喷雾器处理禾本科杂草的防效分别为84.36%~94.40%、74.00%~84.53%,均显著高于担架式植保机处理。综合自走式喷杆喷雾机防效及安全性较好、作业效率较高的优势,应作为规模化小麦生产封闭除草剂喷施主要器械。

To further optimize the use of weed control equipment in wheat fields,plant protection equipment including multi-rotor drone,self-propelled rod-type sprayer,stretcher-type sprayer and backpack-type electric sprayer were selected to spray diflufenican·flufenacet·flurtamone 33%SC as pre-emergence herbicide,and their working efficiencies and weed control effects were compared in 2022.The results showed that the control effects of the four types of equipment on broadleaf weeds were 96.94%~98.98%and 91.98%~95.92%respectively,and those of multi-rotor drone,self-propelled rod-type sprayer and stretcher-type sprayer on grass weeds were 84.36%~94.40%and 74.00%~84.53%respectively which were significantly higher than in stretcher-type sprayer,at 30 and 100 days after herbicide application.Overall,the self-propelled rod-type sprayer should be used as the main plant protection equipment for herbicide application in large-scale wheat production with the advantages of better control effect,higher crop safety and working efficiency.
