摘要
为了解植物生化他感作用在草业（田间杂草）中的作用，１９８６～１９８８年通过查阅资料并对我国大部分牧区和农区实地考察，证明，在植物间广泛存在着因植物次生代谢产物对微生态环境的改变所引起的植物种内和种间生长发育相互促进和抑制的生化他感作用。其中植物间的克生作用（抑制作用）表现的较为明显，而这种作用与草原退化和农田杂草的蔓延有着密切关系。
To know about the action of plant biochemical interaction in prataculture(Weeds on farmland),theauthors sorted out data and made in vestigation on the spot in most pastoral area and agricultural area inChina during 1986～1987. The results showed that among plant species there universally existed ecochemi-cal interaction which was caused by intraplant and interplant growing and developing interstimnulation and in-terinhibitions for plants metabolic secondary products changed the micro一ecoenvironment. The allelopathy(inhibition) among plants was clear,there was a close relationship between this degeneration of grasslandsand spread of weeds.
