广西玉林市超级杂交稻特优233“种三产四”丰产工程技术体系

High Yielding System for Super Hybrid Rice ＂Premium 233＂

超级杂交水稻“种三产四”丰产工程就是通过运用超级杂交水稻新成果，用“三亩”稻田产出现有“四亩”稻田的稻谷总产。水稻单产增加33．3％。也就是说相当于增加了25％的水稻播种面积。袁隆平院士2007年开始实施这个课题，2011年己在我国8省区展开。文章介绍了广西玉林市连续四年实施这一课题的成果。总结了超级杂交稻特优233种子生产和高产栽培的技术体系。

＂Planting Three Producing Four＂ high yielding program for super hybrid rice, which means there is ＂four acres＂ rice production in ＂three acres＂ flee field, using the new achievement of super-hybrid flee. In this way, the rice yield increases 33.3%. It is equivalent to an increase of 25% of the rice acreage. Since 2007, the subject has been in charge of Academician Yuan Longping. Till now, it has been launched in eight provinces in China. This article describes the results of the implementation of this project in four consecutive years of Yulin, Guangxi. And then it summarizes the teelmology system of production and high yield cultivation of super-hybrid Teyou233 rice seed.
