农田杂草是农业生产中的重要问题之一,给农业生产造成巨大损失,长期使用除草剂不仅污染环境,而且杂草易产生抗药性。具有化感作用的植物可以通过向环境中释放化感物质并与杂草竞争生存环境,进而对杂草种子的萌发和生长产生抑制作用。利用化感作用控制杂草不会带来诸如农药残留 Farmland weeds are one of the most important problems in agricultural production, causing huge losses to agricultural production.

Allelopathic plants can inhibit the germination and growth of weed seeds by releasing allelochemicals into the environment and competing with weeds for the living environment.
