In the early season in 2006,a preliminary rice intensification system(SRI) localization technique was made and studied.It was found that low density was the main reason causing rice yield reduction.This study used Liyuanzhan1 as the material to conduct a planting density experiment on high-quality rice intensification system(SRI) localization.The results showed that the growth potential of the rice plant was great and the significant effect of yield increase was obtained under the planting density of was between 166500 to 214500 holes/hm2.However,the seed setting rate and the 1000-grain weight of all the SRI treatment decreased.
