摘　　要：通过在长江中下游主要直播水稻栽培区进行了速除防除杂草试验，明确了速除450—600g.a.i．／hm^2可以有效防除千金子、稗草、异型莎草、陌上菜、鸭舌草等杂草，施药40d后总防效超过98％。通过多点示范的结果可以看出，最佳施药时间宜选择在水稻播种3d以后，秧苗-叶-心期之前。在此期间内施药，对水稻秧苗是安全的。示范试验还明确了速除可以在长江中下游的直播种植区进行使用。Application techniques of Suchu herbicide for controlling weeds were studied in direct; seeded rice fields in the Middle and Lower Reaches of the Yangtze River. The results showed that suchu was highly effective on Echinochloa crusgalli , Leptochloa chinensis , Cyperus difformis , Monochria vaginali, Lindernia procumbens etc. The overall control percent was over 98 % at the dosage of 450 - 600 g a. i./hm^2 on 40th after treatment. The best usage period was between 3 days after seeding and before 1.5 leaf. In this period, it was safe to rice seedling. The result of trial showed !that it was suitable in the major direct seeded rice fields in the middle and lower reaches of the Yangtze River.
