Chemical control on crops" stands for Chemical control of crop growth and development. Scientists have been concentrated on study of apply technology and basic research of plant hormones, making possible or reality of plant growth substances on controlling of crop growth and developments. So far many chemical control technology are contributing to yield increments of many crops. Great efforts was put on the research and development of GA3,Ethephon,Pix,PP333 in China, and also great benefits had been achieved... Chemical control on crops" stands for Chemical control of crop growth and development. Scientists have been concentrated on study of apply technology and basic research of plant hormones, making possible or reality of plant growth substances on controlling of crop growth and developments. So far many chemical control technology are contributing to yield increments of many crops. Great efforts was put on the research and development of GA3,Ethephon,Pix,PP333 in China, and also great benefits had been achieved from the above apply technology.It is predicted that the top three important crop technology will be crop breeding,bioengineering technology and chemical control of crop growth and development. The chemical control technology will play a key effects on variety selection, increment of cropping time by short-circuit, increasing work efficiency, stress cultivation and in crop super high yielding cultivation. “作物化控”系作物生长发育的化学调控的简称.由于科学家致力于植物激素理论研究和应用研究,使得应用植物生长物质有效地调控作物生长发育诸多的进程成为可能,并由此形成了许多效益显著的作物化控技术.作者预计21世纪的作物生产仍然首举遗传育种技术、生物工程技术,其后,作物化控技术仍然会发挥一定的生产力作用. This paper summarized the rise and trend of chemical control of crop growth as well as its achievement and limitations. It also introduced the concept, background, importance and research orientation of crop substance cultivation (CSC). In the view of authors, the high-tech CSC engineering should be developed in the future. 本文概述了作物化控的兴起、发展动态和大田作物化控的成就与局限性 ;分析了作物物化栽培产生的背景、意义及研究方向 ,提出今后应发展以高新技术作支撑的物化栽培工程
