【摘要】 本文在温室条件下,采用盆栽试验方法,研究了苯噻草胺和苄嘧磺隆混用的联合作用类型及对水稻的安全性。试验结果表明,苯噻草胺与苄嘧磺隆混用对1.5叶期稗草和2~3叶期眼子菜表现为相加作用。二者单用或混用对移栽水稻、抛秧水稻较为安全;对1叶期直播水稻则有抑制作用,不宜使用。更多还原

【Abstract】 This paper deals with the joint- action of the herbicide combination of mefenacet with bensulfuron- methyl against baryardgrass(Echinochloa cms- galli) and pondweed(Potamogeton distinctus),and its safety to rice plants under greenhouse conditions.The results were as follows:① The joint- action of combinations of mefenacet with bensulfuron- medryl against 1.5 leaf- stage baryardgrass and2 to 3 leaf- stage distinct pondweed were additive.② The application of mefenacet with bensulfuron-methyl combinations in the experimental rates was safe for transplanted rice(transplanting depth was 2 to3cm) and seedling- throw rice(throwing the rice seedlings on soil surface).③The rice injury was observed in the treatments of direct- seeding rice at 1 leaf- stage after the application of mefenacet and of its combinations with bensulfuron- methyl.更多还原
