摘　　要：以猪粪为研究对象,采用高温好氧模拟堆腐试验,研究了外源添加剂沸石对猪粪腐解过程中可溶性盐的动态变化规律。结果表明：不同用量的沸石均不同程度的降低了猪粪堆腐中可溶性盐的含量。5%和10%中高添加量的沸石处理与对照相比差异达显著水平;不同添加量的沸石处理间差异显著。非金属矿物沸石作为外源添加剂可以有效的控制猪粪腐解中可溶性盐的含量,减少其潜在的危害。Taking pig manure as object,the soluble salt change of pig manure by supplying zeolte with high temperature aerobic composting were studied.The results showed that in the process of pig manure composting,soluble salt content of manure was remarkably reduced by supplying zeolite.Between the 5%,10%of zeolite application and manure was a significant difference level（P〉0.05）.Through the LSD multiple comparisons,between the 2%,5%and 10%of zeolite was a significant difference level（P〉0.05）.Non-metallic mineral zeolite as additives can be effective control of soluble salt content,reduce its potential environmental hazards.
