摘要
针对晚稻免耕抛秧前施除草剂需反复灌水,存在耗水多、周期长、增加成本、污染农田环境等问题,进行晚稻抛栽前免耕免用除草剂试验,可提早5~6d进行抛栽,每公顷增产稻谷130.5kg,节省工日17.5个,节约成本135~200元。
Because it needs to irrigate repeatedly on applying the herbicide before seedling-broadcast with no-tillage in late rice, the problems including large water consumption and long periodical, additional cost and field environment pollution, etc are caused. To solve these problems, the experiment on seedllng-broadcast with no-tillage without herbicide application in late rice was conducted. The results showed that seedling-broadcast could be carried out 5-6 days earlier; the increase of yield of rice grain was 130.5kg/hm^2, and the saving manpower was 7.5/hm^2. The reduced cost was 135-200 RMB Yuan/hm^2.
