农作物化控栽培工程技术的发展与中国农业现代化前景

THE ENGINEERING DEVELOPMENT OF CHEMICALLY-MANIPULATED CROP CULTURE IN RELATION TO THE PROSPECT OF AGRICULTURAL MODERNIZATION IN CHINA

人均耕地不足是我国种植业最根本的资源制约,农业技术的最大课题就是寻求耕地不足的技术替代。化控栽培工程是化控措施与传统技术相互配合而诱变出的新的技术组合,对作物生长发育可以进行外部条件加内部激素水平的双重调控,从而为农业栽培展示了夺取更高单产的极大可能。80年代以来,我国在农作物化学控制工程技术研究和应用领域已取得多项进展。本文讨论了化控在修饰良种、革新传统栽培技术和建立定向诱导的模式栽培等方面的意义,指出化控栽培工程在实现多熟复种制的高产稳产上具有不可替代的重要功能。并提出了加强作物化控栽培的理论与方法研究的必要性及其要点。

The shortage of farm land per person is the most foundamental limiti- ng factor to farming in China.The biggest research project of agricultural techniques is to find technological replacement for the shortage of farm land.Chemicalcontrolled crop culture engineering is a new technological complex induced through the combi- nation of chemical(Plant Growth Regulators)application and traditional techniques, and this combination could manipulate the growth and development of crops through both external factors and internal hormone levels,therefore,it shows hat there are more potential for high yield crop cultivation.A lot of progress has been made in the fields of research and application of chemical control techniques in our country since 1980.This paper discussed the significance of modifying crop variety reforming traditional culture techniques,and setting up the model of cultivation toward de- finite direction with chemicals(PRG).It pointed out the importance of chemically- controlled crop culture engineering in multi-cropping system for high and stable yi- eld.This paper also put forward the necessity and outline of paying more attention to the theory and research method for the chemically-controlled crop culture enginee- rings.
