摘　　要：为明确激健助剂与机插秧稻田除草剂减量混用对机插秧水稻安全性及其增效作用,本文比较了机插秧稻田3种封闭除草剂配方和3种茎叶除草剂配方的常量处理和相应配方减量40%添加激健处理对机插秧稻田杂草的防除效果及对机插秧水稻安全性的影响。结果表明,供试除草剂配方常量处理与减量40%处理均对机插秧水稻安全,封闭除草剂配方35%丙噁·丁草胺水乳剂+19%氟酮磺草胺悬浮剂组合和茎叶除草剂配方3%氯氟吡啶酯乳油+100g/L氰氟草酯乳油组合、10%噁唑·氰氟乳油+38%二甲·灭草松水剂组合、60g/L五氟·氰氟草可分散油悬浮剂+38%二甲·灭草松水剂组合的常量处理与减量处理对机插秧稻田杂草均有较高防效,且常量处理与减量处理之间差异不显著。这说明激健助剂对机插秧稻田杂草防除具有积极的作用。In order to clarify the effects of combination of Jijian adjuvant and herbicide reduction on the safety of machine-transplanted rice and its synergistic effect,this paper compared the weed control effect and safety of three closed herbicides formulations and three foliar-applied herbicide formulations at conventional dosage and conventional dosage reduction of 40%mixed with Jijian adjuvant in machine-transplanted rice fields.The results showed that the constant treatment and decrement treatment of the tested herbicide formulations were safe for machine-transplanted rice.The constant treatment and decrement treatment of the closed herbicide formulations of 35%oxadiargyl·butachlor EW+19%triafamone SC,and the foliar-applied herbicide formulations of 3%florpyrauxifen EC+100 g/L cyhalofopbutyl EC,10%metamifop·cyhalofop-butyl EC+38%2-methyl-4-chloro-phenoxyacetic acid·bentazone AS,and 60 g/L penoxsulam·cyhalofop-butyl OD+38%2-methyl-4-chloro-phenoxyacetic acid·bentazone AS had high control effects on weeds in machine-transplanted rice fields,and the difference between the constant treatment and decrement treatment was not significant.It shows that the Jijian adjuvant has a positive effect on weed control in machine-transplanted rice fields.
