Abstract：In order to better utilize cow dung and garden waste as resources, as well as reduce peat mining,the seedling test of Robinia pseudoacacia using cow dung and green waste compost as cultivation substrate was undertaken. There were six treatments in total: T1(100% cow dung compost),T2(75% cow dung compost and 25% of garden waste compost ) , T3 ( 50% cow dung compost and 50% of garden waste compost),T4(25% cow dung compost and 75% of garden waste compost) and T5(100% of garden waste), CK(100% peat). Seven indexes including height,diameter,root length,biomass,chlorophyll content,and contents of nitrogen(N),phosphorus(P) and potassium(K)were measured,and the membership function method were employed to do the comprehensive evaluation and analysis. The results indicated that the pH values in T4 and T5 treatments were 8. 57 and 8. 31,and the EC values were 0. 87,0. 56 dS/m,which were lower than T1—T3 treatments and in the appropriate range of plant growth. The height,diameter,root length,biomass,contents of chlorophyll and main nutrients of R. pseudoacacia in T4 and T5 treatments were higher,which were close to or higher than the plants in CK. The comprehensive evaluation indexes of plants in T4 and T5 treatments were 0. 706 and 0. 832,which were higher than 0. 602 in CK. Therefore, the matrix in T4 and T5 treatments can be used as alternative substrates of locust breeding.
