中文摘要：

化感作用是植物普遍存在的一种化学防御机制，它对于植物的生长发育以及生存竞争有着重要意义。为了有效解决农业生产和生态平衡中出现的问题，本研究总结了牧草化感作用在杂草控制、混合种植、生物入侵、生态恢复4个方面的应用，归纳了杂草化感作用在各应用中的研究进展、应用方式及当前所存在的问题。对于牧草化感作用今后的研究，提出了将室内探究与田间实验相结合、客观分析环境条件在化感作用中的地位、深入探究化感物质作用机理等建议。

英文摘要：

Allelopathy is a chemical defense mechanism, which is a universal phenomenon in plants. It plays a significant role in growth, development and competition of plants. In order to solve the problems coming from agricultural production and ecological balance effectively, the paper summarized the allelopathy applications of forage in weed control, mixed planting, biological invasions and ecological restoration, including the research progress, application methods and current problems. For future research on the allelopathy applications of forage, proposed that both laboratory experiments and field experiments should be designed, the environmental conditions in allelopathy should be analyzed objectively; the mechanism of allelochemicals should be explored deeply.
