摘要
文章总结归纳了目前国内畜禽粪便厌氧消化沼液还田的应用现状。不同发酵原料的沼液成分存在差别,但均含有丰富的营养物质;阐述了沼液还田对于提高土壤肥力、农作物产量和品质均有积极作用,但大量施用时会对水土环境和农作物带来安全风险;对于沼液的无害化处理技术进行了综述。
The current situation of biogas slurry irrigation was summarized in this paper. Slurry from livestock manure anae- robic digestion contains large amount of nutrients. Different slurry from different raw material fermentation has different nu- trient components. It showed that the slurry could played a positive role in improving soil quality, crops quality and yields, However,an excess use of biogas slurry could lead to the pollution risks on water and soil environment, and also on crops. The Hazard-free treatment technology for biogas slurry safety utilization are also reviewed
