摘要
探讨了有机除草杀虫药肥对水稻的施用效果。结果表明:追施有机除草杀虫药肥25 kg/667m~2,药后45 d对稻田稗草、异型莎草、阔叶草等一年生杂草总体株防效和鲜重防效分别为94.8%~96.3%、95.6%~97.7%,药后15 d对二化螟防效为95.8%~96.8%,平均增产率14.9%,平均增加纯收入133.9元/667m~2,经济效益可观,且操作简单、方便,省工省力,值得大力推广。
The application effect of herbicidal and insecticidal organic fertilizer on rice was studied. According to the results, 45 days after topdressing of 375 kg/hm~2, the plant control efficacy for annual weeds such as Echinochloa crusgalli, Cyperus difformis and broadleaf weeds was 94.8%-96.3%; and the fresh weight control efficacy was 95.6%-97.7%. 15 days after implementation, the control effect on Chilo suppressalis was 95.8%-96.8%. The yield increased by 14.9% and net income by 2 008.5 yuan/hm~2 averagely. Benefited from the considerable economic profits, and simple, convenient and labor-saving operation, herbicidal and insecticidal organic fertilizer is worth to extend.
