摘　　要：论文论述了植物化感的特点及温、光、肥、水、微生物等环境因素对化感作用的影响,从自然资源可持续利用的角度系统地分析了化感资源在农作物生产中的应用潜力,提出选育化感品种以提高作物的资源利用和抗逆能力,利用植物化感原理合理作物类型搭配和指导农作物的种植、耕作、水肥管理和病虫草害防治,以及开发对环境污染较轻的化感农药等观点,旨在推进农作物的优质、高产、高效、安全生产和农业的可持续发展。Allelopathic characteristics in plants, and effects of environmental factors, including temperatures, light, fertilizer, in＇igation, and microorganism, on allelopathy are discussed in this paper. Applications of allelopathy in crop production are systematically outlined and analyzed in view of enhancing sustainable utilization of natural resources. It was proposed that plant allelopathy can be used in crop breeding for improving weed and fungi tolerance, in crop planting system for alleviating allelopathie toxicity, and leading to better agronomic practices, including rational planting density, cultivation, irrigation and fertilization, and in pest control for reducing yield loss. Effective use of plant allelopathy may be helpful for improving crop quality, yield and environmental conditions.
