摘要
通过对沼渣、沼液的营养组分、有毒有害物质和卫生指标进行系统的监测,得出有代表性的数据应用于生产。通过分区域对不同品种的果树和蔬菜的田间试验,观察施用沼渣、沼液与化肥配合的不同比例对水果和蔬菜在品质、产量方面及试验地土壤成分变化的影响,依据国家相关标准验证了沼渣、沼液作肥料对农产品安全性的影响,为沼肥的规范化施用提供了依据。
Nutrition composition,harmful substances and health indices of digestate,including biogas residue and biogas slurry,were monitored,and the representative data were drawn for real application.Field trials of fruit and vegetable fertilized with different mixing ratio of digestate and chemical fertilizer were conducted to compare the quality of fruits and vegetables,the yields,and the change of soil composition.Effect of biogas digestate applicaton on the safety of agricultural products were measured,providing the basis for digestate standardized application.
