摘要
沼气系统中产生的副产品沼渣和沼液(沼肥)含有丰富的有效养分和植物活性物质。施用沼肥对作物生长和土壤改良具有显著作用,但盲目施用也会造成作物减产和环境污染。就不同原料的沼肥特点、沼肥对植物和土壤的作用机理及其在生产应用中应注意的问题展开讨论,为合理利用沼肥提供理论依据。
Biogas residue and biogas liquid（biogas manures）are the byproducts of biogas system,which contains rich effective nutrient and plant active substances.Applying of biogas manures have significant effect in the crop growth and the soil improvement.However,blindly applying of it can also reduce the crop yields and pollute the environment.In this article,the biogas manures characteristics that comes from different materials,the mechanism of biogas manures effect on plant and soil ,the problems in its applying were discussed.The article aims at providing some evidence on the reasonable utilization of biogas manures.
