摘要
本文对滹沱河流域稻田杂草的化学防除作了进一步的研究。以五二扑与当地主要推广的除草剂苄磺隆相比较 ,具有杀草谱广 ,对稻田主要杂草眼子菜的杀灭速度快。适当提早施药期 。
The research was conducted to determine the effect of chemical weed control in rice field in Hutuo River area.Compared with Bensulfuron methyl which is the main herbicide used locally,PCP+Na+MCPA+Nap+Prometry with wide weed controlling spectrum,can kill quickly Potamogeton distinctus in rice fields.The experiment also showed that early application of Pcp+Na+MCPA+Nap+Prometryne could control the growth of Echinochloa crusgalli and Cyperaceae weeds.
