| 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./hm2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。

| Abstract: | Application techniques of herbicide "Suchu" for controlling weeds in direct-sowing rice fields were studied in 2003~2004.The results showed that applying "Suchu" 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. |
