摘要: 作物-杂草化感作用是作物与杂草之间生态位竞争的重要机理之一。利用作物-杂草化感作用和生态位理论解决实际农业生产中的生态学问题具有重要意义。本研究就作物-杂草化感作用与其生态位的内在联系进行初步探讨,从生态位理论入手,对农作物及其杂草化感作用等个体或微观生态学研究在宏观生态学中的应用进行探讨,并据此进行推导在野外生态环境中强化对杂草具有强化感抑制作用的作物品种的人工选择和合理布局,可以实现杂草的整体防控和宏观生态评价,为下一步“基于生态位理论的作物-杂草化感作用研究”提供理论基础。

Abstract: Crop-weed allelopathy is one of the essential mechanisms of niche competition between crops and farmland weeds. It is significantly important to solve ecological problems by applying crop-weed allelopathy and niche theory in practical agricultural production. In this article, the underlying contact of crop-weed allelopathy and its niche is preliminarily explored. The subject is illuminated via niche theory. Applications of the study in macro-ecology on individual-ecological or micro-ecological issues, such as the crop-weed allelopathy are discussed from a macro-ecological perspective. A macro-ecological assessment for preventing and controlling farmland weeds can be achieved by strongly enhancing artificial selection and rational distribution of strongly allelopathic crop varieties which have inhibiting effects on farmland weeds in a field ecological environment. The article can provide a theoretical basis for further “Study of crop-weed allelopathy based on niche theory”.
