摘　　要：总结和归纳了国内外部分关于沼液农田施用增产提质效应及对水土环境影响的研究成果,表明沼液对于提高作物产量与品质、促进植物种子萌发、防治病虫害、提高土壤养分含量具有积极作用,但大量施用时对于水土环境存在污染风险。说明在沼液施用程中,应充分考虑作物及农田对于沼液的承载能力,在对土壤及地下水没有污染的前提下选择用量,对其在农产品生产中的安全性进行系统、定量的监测和安全评价,这样既能节省对化肥的需求,减少农民的生产成本,又为沼气工程处理沼液提供了科学指导,有利于预防农田消纳沼液时潜在的环境风险发生。This paper comprehensively summarized the research results from domestic and foreign studies of the effect of biogas slurry farmland application on plants yield and quality,and the effect on water and soil environment.It showed that biogas slurry played a positive role in improving the quality and yield of crops,improving plant seed germination,prevention and treatment of plant diseases and insect pests,and improving soil quality.However,an excess amount of biogas slurry application could lead to the pollution risks of water and soil environment.It should fully consider the land carrying capacity for biogas slurry and choose appropriate dosage which had no pollution on soil and groundwater,so that the demand of fertilizer could be saved and the production cost of farmers could be reduced.It could provide scientific guidance for biogas project handling biogas slurry.
