摘要
腐植酸作为一种天然的高分子有机混合物,其在实现"土肥和谐"中的作用已经引起广泛关注。本文在介绍腐植酸来源及结构特点的基础上论述了腐植酸对植物生长的促进作用,主要包括直接刺激植物根系生长和对养分的吸收、增强植物的抗逆性、提高土壤及肥料的养分利用率、调控土壤微生物及酶的活性等方面;综述了腐植酸对植物的促生作用和机理;为腐植酸在农业生产中的高效应用提供了理论基础。
As the natural organic mixture,humic acid has attracted much attention for its function in＂a harmonious relationship between soil and fertilizer＂.In this study,the roles of humic acid on promoting plant growth were discussed based on the introduction of the sources and structural characteristics,focusing on stimulating roots growth,promoting nutrition absorption,strengthening the resistance of plants,improving nutrient utilization of soil and fertilizer,regulating microbial and enzyme activity in soil,etc.The effects and mechanisms of humic acid in prompting plant growth were summarised,which was in order to provide a theoretical basis for the efficient application of humic acid in agricultural production.
