摘　　要：餐厨垃圾有机质含量高、微量元素丰富,其主要农业资源化利用是制备贫瘠土壤改良剂、污染土壤修复剂。本文主要采用田间小区试验,以纯沼渣为对照,研究餐厨垃圾沼渣与有机肥的不同配比对土壤理化性质的影响。结果表明:不同配比的餐厨垃圾沼渣与有机肥对土壤p H值的影响不显著,但是与对照相比,添加有机肥的土壤总盐含量显著下降,土壤有机质含量、氮含量、速效磷含量、速效钾含量显著增加。沼渣∶生物复合肥∶有机肥=50%∶35%∶15%时综合效益最优。因此,相对于施加纯沼渣,合理配加其他有机肥更有利于改善荒漠区土壤理化性质。The food waste has high content of organic matter and rich trace elements,and its main agricultural resource utilization is to prepare barren soil improvers and contaminated soil remediation agents.Using the application of pure biogas residue as the control,this paper conducted a field plot experiment to study the effects of different ratios of food waste biogas residue to organic fertilizer on the physical and chemical properties of soil.The results showed that different ratios of food waste biogas residue and organic fertilizer had no significant effect on the p H value of soil.Compared with the control,the total salt content of soil applied with organic fertilizer significantly decreased,and the contents of organic matter,nitrogen,available P and available K significantly increased.The comprehensive benefit was optimal when biogas residue∶biological compound fertilizer∶organic fertilizer was 50%∶35%∶15%.Therefore,compared with the application of pure biogas residue,reasonable addition of other organic fertilizer is more beneficial to improving the physical and chemical properties of the desert soil.
