超级稻“三定”栽培法研究Ⅰ概念与理论依据

Studies on San-Ding Cultivation Method for Super RiceⅠ.The Concept and the Principle

总结了国内关于水稻和超级稻高产栽培的基本生物学规律及其高产栽培技术研究的经验,提出了定目标产量、定群体指标、定技术规范的超级稻“三定”栽培法,并论述和讨论了“三定”栽培法的概念及其理论依据。指出超级稻品种有其适宜的种植区域,在不同生态区域种植的超级稻产量表现不同。生产上应按照超级稻的种植区域,以确定适合的栽培目标产量,采用与目标产量相一致的定量化栽培技术和群体发育调控技术,实现高产稳产高效的超级稻生产。

This paper summarized the basic biological rule and the cropping experiences from domestic and foreign researches on high yielding cultivation in rice and super rice, and supposed the San-Ding cultivation method for super rice, i.e., to quantify the target yield, to quantify the population indexes and to quantify the cultivation techniques. This paper also discussed and stated the concept and the principle about the San- Ding cultivation method. Super rice has the optimum ecological area of high yielding cultivation and the different yield appearance in different growing regions. In order to realize the high and stable yielding cultivation of super rice, the possible way is firstly to quantify the proper target yield of super rice cultivation according to growing regions, then to regulate the population quality indexes in accordance with the target yield through the practical use of relative cultivation techniques for super rice.
