摘　　要：将畜禽粪便经过厌氧发酵后产生的沼液通过滴灌系统滴入植物根部附近土壤的一种施用方法叫沼液滴灌。滴灌沼液可以改良土壤、提高作物产量、改善作物品质,但同时会增加污染土壤的风险。本文综述了沼液滴灌对土壤理化性质的影响、沼液滴灌浓度选择、沼液滴灌优势,并展望了沼液滴灌未来发展方向,以期为沼液滴灌技术研究和推广应用提供参考。Biogas slurry drip irrigation is an application method that drips the biogas slurry produced by anaerobic fermentation of livestock and poultry manure into the soil near the root of the plant through the drip irrigation system.Biogas slurry drip irrigation can improve soil,increase crop yield,and improve crop quality,but it also increases the risk of soil pollution.This paper summarized the impact of biogas slurry drip irrigation on soil physical and chemical properties,the selection of biogas slurry drip irrigation concentration,the advantages of biogas slurry drip irrigation,and looked forward to the future development direction of biogas slurry drip irrigation,in order to provide references for the research,promotion and application of biogas slurry drip irrigation technology.
