Research Progress on the Application of Humic Acid Fertilizers in Horticultural Crops
The application of chemical fertilizers is one of the important ways to improve the yield and quality of horticultural crops.However,long-term unreasonable use of chemical fertilizers will lead to problems such as decreased soil quality,imbalanced microbial structure,and decreased crop yield and quality.Humic acid fertilizers,which use humic acid as a synergist,have a positive effect on improving soil,increasing crop yield,quality,and stress resistance.In order to promote the promotion and application of humic acid fertilizers in horticultural crops,the use of humic acid fertilizers in improving soil,increasing fertilizer utilization,promoting horticultural crop growth,enhancing horticultural crop stress resistance,improving horticultural crop yield and quality are both analyzed and summarized.The future application and research directions of humic acid fertilizers in sustainable agriculture are prospected.
