摘　　要：对油菜收获后的水稻免耕直播田使用不同除草剂控制杂草的发生,示范试验结果表明:对稗草、异型莎草、陌上菜、节节菜、千金子等杂草的总体株防效和总体鲜重防效分别达到85.05%以上和95.17%以上。每hm2节约成本1500元以上,每hm2产量两优培九除草处理较不除草处理高51.2%。该技术省工省时、节约成本,是一项可行的、值得推广的轻简栽培技术。The different herbicides applied on middle rice field without tillage after rape harvest can control weeds ,and have no harm on rice growth , The demonstration results showed that the total density and fresh weight efficacy of controlling those weeds such as Echinochloa crustacean, Cyperus difformis, Lindernia procumbens, Rotala indica, Leptochloa chinensis was more than 85.05% and 95, 17% , respectively. This plant pattern reduced cost more than one hundred yuan （RMB） per mu. The yield per mu of Liangyoupeiju with weed clearing was 51.2% higher than without weed clearing. This technique is viable, time - saving and worth popularization.
