水稻旱育精作时空理论与技术研究

Study on theory of time and space and technique of rainfed nursery and intensive cultivation for rice

水稻生长发育是在四维时空连续区内进行 ,水稻旱育精作技术以延时扩空为技术框架 ,通过精播旱育持续分蘖长龄秧 ,适应当地气候特点渡过干旱的春季和生产上的枯水期 ,为等雨借汛延缓插秧创造条件 ,缓解缺水的矛盾。运用时空栽培原理将稻作群体质量从定性引入定量研究 ,构成了水稻旱育精作的精播、精插。

The growth and development of rice is continuous in terms of time and spatial distribution The technique frame of rainfed nursery and intensive cultivation is prolonging time and enlarging space occupied by the rice Continuously tillering and long-age seedlings are got by intensive sowing and rainfed raising, in order to pass through drought spring and dry stage, wait rain and take advantage of monsoon season, and provide conditions for delaying transplanting Rainfed nursery and intensive cultivation is composed of intenstive sowing, intensive transplanting and intensive management, which is based on the theory of time and space
