应用化控技术改变作物的生理特性,使之更符合人类要求,已引起世界各国科技工作者的重视。美、苏、日、西德等国对赤霉素,干扰素、整形素、Br等激素的研究已取得令人瞩目的成果。在我国,六十年代开始对矮壮素和赤霉素在农业上的应用进行了研究,七十年代又开展了乙烯利,缩节胺等类外源激素在农业生产上的大面积应用,并取得了较好的经济效益。在前人研究的基础上,我们综合各种生长激素(特别是外源激素)的特性和使用方 Application of chemical control technology to change the physiological characteristics of crops to make it more in line with human needs, has attracted the attention of scientists from all over the world. The United States, the Soviet Union, Japan, West Germany and other countries on gibberellin, interferon, steroids, Br and other hormones have made remarkable achievements. In China, the application of CCC and gibberellin in agriculture began in the 1960s. In the 1970s, large-scale application of exogenous hormones such as ethephon and diflubenamide in agricultural production was carried out. And achieved good economic returns. On the basis of previous studies, we combine the characteristics and use of various growth hormones (especially exogenous hormones)
