作物的化感作用对杂草生长能产生有效的干扰作用,这一发现启发人们利用这种现象进行杂草治理——利用对杂草有毒害作用的植物残枝败叶以及植株根部所释放的毒素防除杂草。后者即是化感作用的典型表现形式,而且是在一年生作物上开发作物化感作用的一种最有效的途径。作物化感作用是 The allelopathy of crops can produce effective disruptive effects on the growth of weeds. This discovery has inspired people to use this phenomenon for weed control - using the decayed leaves of plants and the toxins released from the roots of plants that are toxic to weeds Control weeds. The latter is a typical manifestation of allelopathy and one of the most effective ways to develop the allelopathic effect of crops on annual crops. Allelopathy of crops is
