摘要
采用田间系统观察和小区试验方法 ,阐述了上海市浦东地区浅耕旱条播稻田杂草发生种类、特点和消长规律 ,客观评价了若干化除配方的除草效果及对水稻的安全性 ,提出了浅耕旱条播稻田二次主体防除策略 ,筛选出“扫弗特→农得时 +高杀草丹”、“扫弗特→农得时 +稗草净”等配方 ,基本解决了浅耕旱条播稻田杂草危害。
By systematic field observation and plot experiment, the species,behavior and growing and declining regularity of weeds occurring in post-light-tillage direct-drilled dry rice field were investigated in Pudong district of Shanghai. The effects of several chemical weed control methods using different herbicides and the safety of controlling methods were also evaluated. Then the strategy of controlling main weeds in twice was suggested. The formulas“Pretilachlor→followed by Bensulfuron-methyl+Benthiocarb”( which means utilizing Pretilachlor first and utilizing the mixture of Bensulfuron-methyl and Benthiocarb secondly, the same below), and “Pretilachlor→Bensulfuron-methyl+Quinclorac” were selected, which could basically meet the demand of controlling weeds in post-light-tillage direct-drilled dry rice field .
