摘　　要：针对杂交水稻组合Ⅱ优162开展了高产栽培模式研究.采用二次回归正交旋转组合设计,考察施N量、施P量、施K量、密度和播期5个因素.对回归方程进行了统计选优,降维分析,边际效应分析.结果表明,各因素的重要性依次为:播期、密度、施N量、施K量、施P量.高产栽培模式要点为:施N量10.7～11.3kg纯N/667 m2,施P量17.0～19.0 kg过磷酸钙/667m2,施K量13.0～14.3 kg氯化钾/667m2,栽插密度为1.52～1.55万窝/667m2,播种期安排在3月26～28日.For Ⅱ - you 162 which is a super high yield combination of hybrid rice, the cultivation pattern of high yield was analyzed with the device of secondary regression orthogonal rotary combination. In this study, there are five factors investigated. They are N nutrition, P nutrition, K nutrition, planting density and sowing date. For the regression equation, statistical optimum choosing, and the analysis of dimension reduced and margin effect has been analyzed. The results reveal that five factors are in this following order of importance： sowing date, planting density, N nutrition, K nutrition, P nutrition, and that the main points for the pattern of cultivation are： application dose of pure nitrogen is 10.7-11.3 kg/667 m^2, application dose of calcium superphosphate is 17.0-19.0 kg/667 m^2, application dose of potassium chloride is 13.0-14.3 kg/667 m^2, planting density is 15200-15500 hills/ 667 ^m2 and sowing date is 26-28th, March.
