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。
Weed control of weeds was conducted on no-tillage and direct-seeded rice fields after rapeseed harvest. The results of demonstration experiments showed that the resistance of weeds to barnyard grass, alien sedge, Effectiveness and overall fresh weight control efficiency reached more than 85.05% and 95.17% respectively. Each hm2 cost savings of more than 1,500 yuan per hm2 yield Liangyou Pei nine weeding less weeding treatment 51.2% higher. This technology saves time and saves costs, which is a feasible and worthwhile promotion of light-cultivation techniques.
