摘  要:
[目的]筛选水稻田杂草千金子、稗草的有效药剂。[方法]通过小区试验研究了惠茎1号、惠茎2号和五氟磺草胺等除草剂对水稻田千金子、稗草的防治效果。[结果]在千金子防治上,各处理最终效果均达100%。对于稗草防治,陶氏益农生产的17%稻喜1.2 kg/hm~2的除草效果最好,产量也比对照药剂增加2.58%,其次是惠茎1号1.2 kg/hm~2,产量比对照药剂增加1.80%,江苏华农生物化学有限公司生产的氰氟嘧啶肟1.2 kg/hm~2,产量比对照药剂增加1.06%。该3种药剂处理下的水稻苗数较对照略有增加,后期株高无差异,安全性好。[结论]该研究结果为水稻田稗草和千金子的防治提供了理论依据。

摘  要:
[Objective] The aim was to screen out effective herbicides for Echinochloa crusgalli( L.) Beauv. and Leptochloa chinensis( L.)Nees. in rice field. [Method] We studied the control effect of some herbicides like Huijing 1,Huijing 2 and Penoxsulam against Echinochloa crusgalli( L.) Beauv. and Leptochloa chinensis( L.) Nees. in rice field through plot test. [Result] For the Leptochloa chinensis( L.) Nees.,every herbicide showed the same effect,up to 100%. But for the Echinochloa crusgalli( L.) Beauv.,their control effects were different. 17%Daoxi from Dow with 1. 2 kg/hm~2 application amount obtained the best control effect,which raised the yielding up to 2. 58%. Next was Huijing1,with 1. 2 kg/hm~2 application amount,and the yield of rice was increased by 1. 8%. The third was Cyanouracil oxime,from Jiangsu Huanong biochemistry Co.,Ltd.,application amount was 1. 2 kg/hm~2,which increased the yielding up to 1. 06%. For the rice growth,under the treatment of the above three herbicides,the seedling number was increased,and had no difference in height,as well as the high safety,compared with the other herbicides. [Conclusion] The results provide theoretical basis for control of Echinochloa crusgalli( L.) Beauv. and Leptochloa chinensis( L.) Nees. in rice field.
