摘要
对21.4%三氟羧草醚水剂茎叶处理防除水田杂草效果及其对水稻的安全性进行研究。结果表明:有效成分用量为225 g.hm-2的21.4%三氟羧草醚水剂能有效防除杂草,对水稻分蘖数、株高、产量无明显影响,且对水稻比较安全。
The effect of 21.4% acifluorfen sodium water aqua on weeds and its safety to the rice were studied.The results showed that when the concentration was 225 g·hm-2,21.4% acifluorfen sodium water aqua could control the weeds efficiently and has no obvious influence on tiller number,plant height and yield,furthermore the dose was safe to the rice.
