Study on Ratoon Rice High and Stable Yield Cultivation Techniques

[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.
