摘　　要：利用垃圾腐殖土与绿化土对多年生黑麦草和速生杨进行栽植对比试验,结果表明:垃圾腐殖土与绿化土添加质量比为1∶3时植物的生长发育较好;垃圾腐殖土的营养元素含量显著优于一般绿化土,当垃圾腐殖土的添加量≤50%时,既能增加土壤养分、改良土壤,又不会对土壤造成重金属污染。Waste humus soil and greening soil were used to plant perennial ryegrass and fast-growing poplar. The contrastive result showed that the plants grew well, when added mass ratio of waste humus soil and greening soil was 1 ： 3. The nutrient element content of waste humus soil was significantly better than that of general greening soil It not only increased soil nutrient to improve the soil, but also avoided causing pollution of heavy metals to the soil, when the additive amount of waste humus soil was ≤50%.
