腐植酸类物质与植物抗逆性研究进展

Research Progress of Humic Substances on Plant Stress Resistance

腐植酸类物质是一类广泛存在于土壤、水体等的有机物质,对土壤物理、化学、生物性质及植物生长具有十分重要的作用,可通过从土壤、动物粪便、低级别煤等中提取。本文综述了腐植酸类物质促进植物生长发育的生理机制,并分别从抗旱、抗盐碱、抗低温/高温、抗重金属污染、抗病等方面详细介绍了腐植酸类物质对植物抗逆性的影响,最后展望了在可持续农业中腐植酸类物质在作物上的应用和研究方向。

Humic substances（HS） are a series of organic matter found in soil and lakes etc. HS could be extracted from soil,animal waste, and low degrades coal and other organic wastes. HS are very important for soil physical, chemical and microbial properties as well as for plants growth. This review summarized the mechanism of HS on plants growth and also introduced the effects of HS on the plant stress resistances in detailed, including drought resistance, saline-alkali resistance,low/high temperature resistance, heavy metals resistance and disease resistance. The research and application prospects of HS in advanced sustainable agriculture were introduced in the end.
