加强农作物生育信息调控研究建立高产与低风险最佳结合的技术体系

Strengthen the Study on Regulation of Crop Growth Signal System and Establish the Technological Complex With Optimum Combination of High Yield and Low Risk

作者根据近20年以棉、粮作物为对象,在整株水平、群体水平上进行的生育信息(主要是激素系统)规律、调控技术与机理研究工作,探讨了作物管理科学如何从理论到实践纳入21世纪科学整体发展的轨道.提出:①21世纪作物管理需要高产与低风险最佳结合的新技术体系;②作物整株水平的信息调控对品种遗传潜力的充分表达和抗逆潜能的发挥有巨大潜力;③深入研究和发展作物生长发育的“双重调控”理论,创建有中国特色的作物安全高产化学控制栽培工程.

According to twenty years study on the cotton and cereal crops growth signal system (mainly plant hormone system), chemical control techniques and theory from individual plant to whole population level, the authors discuss the development of the traditional crop management how to fit the science trend of the 21st century. The main points of review are summered as follow.(1) The 21st century's crop management must be a new technological complex with the optimum combination of high yield and low risk.(2) The regulation of plant growth signal system at whole plant level can fully bring out the crop's genetic yield potentiality and stimulate the crop's stress-resistant ability.(3) Study and develop the 'double regulation theory' of crop development, establish the chemically controlled crop culture engineering for high and stable yield with Chinese characteristic.
