Abstract: The author was in the capacity of on-job doctorate, participated the project of “The High-Yield and High-Efficiency Technology of Single-season Rice Integration rated and Demonstration in Jiangsu Province”, which was a national grain high yield science and technology project .Some investigation and research have been conducted on the high-yielding fields with yield over 10500kg/ hm2, and reasons of high yield have been analyzed and the experiences have been summarized. There were lots of useful experiences for reference such as: technical lines, cultivation, hinge techniques and the guideline of popularize improved varieties etc. The high - yielding cultivation techniques for late maturing medium japonica rice , raising strong seedlings, widen rows, reducing transplant seedlings and seedlings and disposing population density rationally; adopting” promoting-controlling-promoting” high-efficiency water and fertilizer management, regulating irrigation properly; controlling application of nitrogen fertilizers, increasing application of phosphate and potash fertilizer, reducing the proportion of base fertilizer and tillering fertilizers, increasing earing and grain-filling fertilizers, practicing integrated control of diseases, pests and weeds by chemical and agronomic methods. hinge technique for population quality culture is cultivating sound seedlings, expanding row ledge, reducing seedlings, controlling water and regulating fertilizer rate. Last, and put forward proposals about the rice production for Anhui province and the same area.
