精准轻简高效水稻制种技术研究

An Accurate, Simple and Efficient Rice Seed Production Technology

针对目前水稻制种过程中需肥量大,用药、用肥种类多,费工费时,生产户经济效益不理想的现状。通过采用精准轻简高效水稻制种技术,在不同区域、不同组合、不同季节进行水稻制种大田小区和大田示范试验,比湖南本地习惯水稻制种技术的制种量增产11.4%~21.4%,投入产出比达1∶3.7~1∶8.8,同时简化了农事操作,减轻了劳动强度,大大地提高了经济效益。

Currently, rice seed production needs a large amount of fertilizers as well as various agricultural chemicals and fertilizers, and costs many labors as well as much time. Meanwhile, the economic effects are not ideal for producers.An accurate, simple and efficient seed production technology was applied and rice seed production experiments were conducted in both small zones of the field and the demonstration fields in different regions, combinations and seasons. This new seed production technology brought about a rise of the seeds yield by 11.4% to 21.4% compared to local traditional technology and the investment/output ratio reached 1 ∶ 3.7 to 1 ∶ 8.8. At the same time, the new technology simplified the farming operations, reduced labor intensity, and greatly improved economic benefits.
