再生稻高产稳产栽培技术研究

Study on Ratoon Rice High and Stable Yield Cultivation Techniques

[目的]研究再生稻高产稳产综合配套技术体系对再生稻生长发育的影响。[方法]采用对比试验,分析综合配套技术体系对再生稻产量的影响。[结果]该技术体系比常规栽培增产29.83%,2.88 hm2高产试验田连续3年单产超过3.0 t/hm2,平均单产3.21t/hm2,2007~2009年在自贡市累计示范推广3.18万hm3,增产22.98%。[结论]该综合配套技术体系增产效果十分显著。

[Objective]The research aimed to study the influences of high and stable yield technical systems on ratoon rice.[Method] The influences of high and stable yield technical systems on ratoon rice were analysed by contrast tests.[Result]The results showed that the output of ratoon rice under the new system increased 29.83%,the per unit area yield of the 2.88 hectares high-yield plots was over 3.0 t/hm2 for 3years,the average yield was 3.21 t/hm2,which totally popularized 31.8 thousand hectares as demonstration plot in Zigong from 2007 to 2009,and the output increased 22.98%.[Conlusion]The high and stable yield technical system had a significant effect for increased production.
