| 摘 要： | 通过参与实施张洪程教授主持的国家粮食丰产科技工程“江苏单季稻丰产高效技术集成与示范”项目,对江苏高产水稻进行了深入全面考察,认为,江苏水稻大面积产量重复超10500kg/hm2,从技术路线、栽培理论、关键技术到品种推广的指导思想等方面有很多经验值得借鉴:偏迟熟水稻北移,充分利用光温生态生产潜力,是大面积产量进一步提高的前提;高产群体质量的优化调控,是高产的技术理论基础;“壮秧、扩行、减苗、调肥、控水”是其高产的关键技术。据此引发思考并对安徽及同类地区水稻生产的发展提出建议。

| 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. |
