本文结合国家科技攻关项目粮食丰产科技工程的实施,通过对安徽沿江江南轻型丰产栽培核心试验示范区、丰产示范区以及667hm2辐射区典型代表田块进行经济分析和技术经济评价,得出双季稻轻型栽培技术体系中“早直播-晚抛秧”和“双季双抛”两种主体技术模式能显著降低劳动强度,提高劳动生产效率,节省物化投入,实现产量、效益同步提高。
Based on the implementation of science and technology project of food science and technology of national key scientific and technological project, through the economic analysis and technical and economic evaluation of the core experimental demonstration area of light and high yielding cultivation along the Yangtze River in Anhui Province, the high yield demonstration area and the typical representative field of 667hm2 radiation area, The two main technical modes of “early direct seeding-evening throwing seedling” and “double-season double-throwing” in light-cultivation technology system can significantly reduce labor intensity, increase labor productivity, save material and chemical inputs, and simultaneously increase yield and benefits.
