Abstract: For the purpose of high-yield、high-quality、high-efficiency and sustainable development , how to improve the crop’s yield potential further will be a arduous task for a long time in our agricultural science and technique. The plant chemical control cultivated engineering techniques is a new technological complex induced through the combination of chemical (Plant Growth Regulators) application and traditional techniques. It becomes one of the most active fields in agricultural research and plays great importance in all aspects of crop cultivation. The history and achievements are summarized in the fields of research and application of plant chemical control cultivated engineering technique in our country. The paper emphasized the importance and necessity of chemically-controlled crop culture engineering techniques in Chinese agricultural developments. The tendencies of research and application in plant chemical control cultivated engineering technique are prospected in new century.
