| 摘 要： | 旨在明确助剂激健与机插秧稻田除草剂减量混用是否对机插秧水稻安全以及是否具有增效作用。本试验比较了机插秧稻田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稻安全性影响。结果表明，供试除草剂配方常量处理与减量处理均对机插秧水稻安全，封闭除草剂配方35%丙噁·丁草胺胺EW+19%氟酮磺草胺SC 组合和茎叶除草剂配方3%氯氟吡啶酯EC+100g/L氰氟草酯EC组合、10%噁唑?氰氟EC+38%二甲?灭草松AS组合、60克/升五氟?氰氟草OD+38%二甲?灭草松AS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，说明激健助剂对机插秧水稻杂草防除具有积极的作用。

Synergistic Effect of Adjuvant Jijian on Reducing Dosage of Several Herbicides for the Control Weed on Machine-transplanted Rice Fields |
| |
| Abstract: | This study aims to clarify whether the adjuvant Jijian has a synergistic effect on reducing herbicides for the control of? machine-transplanted rice fields. This experiment was conducted to compare the weed control effect and safety of three closed herbicides formulations and three foliar-applied herbicide formulations in machine-transplanted rice fields, at conventional dosage and conventional dosage reduction of 40% mixed with Jijian adjuvant. 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 oxadiargyl+butachlor (35% EW) and triafamone (19% SC), and the foliar-applied herbicide formulations of florpyrauxifen(3% EC) and cyhalofop-butyl (100g/L EC), metamifop·cyhalofop-butyl (10 % EC) and MCPA and bentazone (38% AS), and penoxsulam·cyhalofop-butyl (60g/L OD) + MCPA and bentazone (38% 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 adjuvant Jijian has a positive effect on weed control in machine-transplanted rice fields. |
