摘　　要：2003～2004年在全国主要的水稻种植区进行了“速除”防除直播稻田杂草的试验和示范,明确了“速除”450～600g ai./hm^2可以有效地防除千金子、稗草、异型莎草、陌上菜、鸭舌草等杂草,施药40d后总防效在98%以上.最佳施药时间以水稻播种3d以后、秧苗一叶一心期之前最好,在此期间内施药,对水稻秧苗是安全的.Application techniques of herbicide ＂Suchu＂ for controlling weeds in direct- sowing rice fields were studied in 2003 - 2004. The results showed that applying ＂Suehu＂ at the dosage of 450 - 600g ai./hm^2 could effectively control Echinochloa crusgall, Leptochloa chinensis, Cyperus difformis, Monochria vaginali, Lindernia procumbens etc, the overall control percent was above 98% after 40 days following application . The best applying time was from 3 days after sowing to 1.5 leaf age, in this period, ＂Suchu＂ was safe to rice seedlings.
