摘要
为弄清40%双草醚悬浮剂对直播稻田杂草的化学防除效果,采用田间试验方法,进行了该试验研究。结果表明:40%双草醚悬浮剂用量以9g/667m2综合表现较佳,既达到安全,又能适度有效抑制田间一二年生杂草的生长,确保直播水稻产量达601.97g/667m2水平,有效解决农村劳动力趋紧的难题。
A field experiment was conducted to know the chemical control effect of 40% bispyribac SC on weeds in direct seeding rice field.The results showed that the comprehensive performance of 9 g/667m2 40% bispyriba SC was optimum,because it was not only safe,but also could effectively inhibit the growth of 1～2 years old weeds and keep the rice yield up to 601.97 g/667m2,thus effectively solve the problem of the decrement of rural labor forces.
