摘要：腐殖酸是由动植物遗骸经过微生物分解转化以及地球化学过程衍变积累起来的一类成分复杂的天然有机物质,其在改良土壤理化性质、促进植物生长、增加农林产量等方面发挥着重要作用。文中综述了腐植酸的特性,根据现有的研究结果探讨腐植酸对土壤、植物的作用机制,解析腐植酸的功能。在此基础上,从促进树木生长、提高树木抗逆性、改良树木生长环境等几方面介绍腐植酸在林业上的应用价值和现状,并对腐植酸在林业上开发应用研究方向进行展望。
Humic acid （HA） is a natural organic matter with complex composition, mainly derived from animal and plant remains decomposition by microorganism and the geochemical processes evolution. It plays an important role in improving soil physicochemical properties, promoting plant growth and increasing crop yields. This paper reviewed the traits of humic acid, discussed the effects of humic acid on soil and plant according to the recent research results, and analyzed the functions of humic acid. On the basis, the value and state of applying humic acid to forestry were summarized from the perspective of promoting tree growth increasing tree resistance and improving tree growth condition, and furthermore some suggestions were proposed for the future research in this regard.
