Brief Description of the Effects of Humic Acid and Soil Fertility on the Yield and Quality of Flue-cured Tobacco
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.
