摘要
植烟土壤酸化、养分失衡和微生物群落结构单一化是影响烤烟产质量的主要不利因素.腐植酸作为一种新型土壤改良剂和肥料,在改良土壤理化性质、提高作物养分利用率和保障国家粮食安全等方面具有重要作用.本文系统梳理了国内学者在植烟土壤和农业上应用腐植酸的研究成果,围绕腐植酸对土壤理化性质、微生物群落结构、酶活性及烤烟产质量等方面开展了比较分析,重点阐述了腐植酸改良土壤与提升烤烟产质量相互影响的机理,并就腐植酸在烤烟生产中的应用提出了3点讨论.
Abstract
Tobacco-planting soil acidification,nutrient imbalance and microbial community structure simplification are the main adverse factors affecting the yield and quality of flue-cured tobacco.As a new type of soil conditioner and fertilizer,humic acid plays an important role in improving the physical and chemical properties of soil,increasing the nutrient utilization rate of crops,and guaranteeing national food security.In this paper,we systematically sorted the research results of domestic scholars on the application of humic acid in tobacco-planting soil and agriculture,and carried out comparative analyses around the effects of humic acid on soil physicochemical properties,microbial community structure,enzyme activity,and the yield and quality of flue-cured tobacco,focusing on the mechanism of the interaction between humic acid in improving soil and enhancing the yield and quality of flue-cured tobacco.Three points were discussed regarding the application of humic acid in flue-cured tobacco production.
