[Objective] The aim of the study was to seek the high yield cultural technology of Chuan-Jiang You 527, a mid-season rice combination. [Method] The effects of N application, cultural densities and cultural models on Chuan-Jiang You 527 were study.[Result] The results showed that the sequence of grain yield in different cultural models was equal-distance between rows(EDBR)＞wide-narrow rows (WNR)＞triangle. The grain yield of EDBR were highly significant increased than ones of triangle in equal cultural density, and there were significant negative correlations between the amount of grain yield and cultural densities. [Conclusion]The high yield cultural technology was N application of 90-150 kg/hm~2,density of 15.16×10~4 hill/hm~2 with EDBRcultural model.
