摘  要：
通过比较MCPA(2甲4氯)、Flur(使它隆)、Rim(砜嘧磺隆)3个单剂和CF(复配剂Ⅰ)、MS(复配剂Ⅱ) 2个复配除草剂对14种禾本科杂草、60种阔叶杂草和3种莎草科杂草的株防效以及对假俭草草坪中杂草的田间小区防除效果,旨在筛选出假俭草草坪的杂草综合防除效果最好的芽后除草剂。结果表明:不同除草剂对杂草的防除效果存在显著差异,除草剂对禾本科杂草的株防效从高到低为MS>CF>Rim=MCPA>Flur;对阔叶杂草的株防效排序为:MS=CF>MCPA=Flur>Rim;对莎草科防除效果排序为MS=CF>Rim>MCPA>Flur。田间小区试验结果也证明,2个复配除草剂(MS和CF)的干质量防效和株防效均显著高于3个单剂处理(MCPA、Flur、Rim)。上述结果表明,2个复配除草剂MS和CF对假俭草草坪中发生的杂草综合防除效果最好,可以推荐作为假俭草草坪芽后除草剂应用。

摘  要：
This study was to screen the effective post-emergence herbicides for Eremochloa ophiuyoidesby testing 3 single herbicides(MCPA, Fluroxypyr, Rimsulfuron) and 2 herbicide mixtures(CF, Clethodim+Flazasulfuron; MS, Mesotrione+Sulosulfuron) on the control of 14 grass weeds, 60 broadleaf weeds, and 3 sedge weeds,and in a E. ophiuyoides plot experiment. The results showed that the different herbicides performed significant different effects in the weed control. The effects of grass weed control was ranked as MS > CF > Rim = MCPA >Flur. The effects of broadleaf weed control was ranked as MS = CF > MCPA = Flur > Rim. The effects of sedge weed control was ranked as MS = CF > Rim> MCPA >Flur. The field plot experiment also confirmed that 2 herbicide mixtures of MS and CF performed significant better weed control than that of 3 single herbicides(MCPA,Fluroxypyr, Rimsulfuron) in E. ophiuyoides. Our results indicated that the herbicide mixtures of MS and CF performed the best weed control and could be recommended as post-emergence herbicides for weed control in E.ophiuyoides.
