摘要
针对内蒙古通辽地区水稻旱作田间主要杂草,开展了除草剂组合筛选试验。试验结果表明,各组合施药后均对目标杂草表现出显著防效。T1、T2、T4、T5的持效期约为25~30 d;T3持效期最长,可达45 d左右,且具有广谱高效的特点。综合药效、持效期及安全性,建议在通辽地区水稻旱作生产中优先选用五氟磺草胺与氯氟吡氧乙酸的组合进行杂草防控。
A herbicide combination screening experiment was conducted for the main weeds in the dryland rice fields in Tongliao,Inner Mongolia.The results showed that all the combinations had significant control effects on the target weeds after application.The residual effects of T1,T2,T4,and T5 were approximately 25 to 30 days;T3 had the longest residual effect,reaching about 45 days,and it also had the characteristics of broad-spectrum and high efficiency.Considering the overall efficacy,residual effect,and safety,it is recommended to prioritize the combination of flumiclorac-pentyl and penoxsulam for weed control in dryland rice production in Tongliao.
