摘　　要：为减少泥炭资源过度使用,提高园林废弃物资源化利用率,探索园林废弃物堆肥作为花卉栽培基质的可行性,选取园林废弃物、泥炭与蛭石作为原料,以不同比例混配,制备成6种栽培基质,以角堇幼苗作为供试植株进行盆栽试验,研究6种栽培基质的理化性质差异以及对角堇生长差异的影响,通过熵权系数与TOPSIS集成比较法对各个指标进行综合比较,筛选出最佳的栽培基质。结果表明,随着园林废弃物堆肥比例的增加,栽培基质的pH值、EC值升高,容重与毛管孔隙度增加,园林废弃物堆肥对角堇的生长有促进作用。综上,最佳基质配方为T3处理,即泥炭:园林废弃物堆肥∶蛭石=2:3:1,可以作为角堇生长栽培的替代基质。In order to reduce the overuse of peat resources and improve the utilization rate of garden waste resources,the feasibility of using garden waste compost as flower cultivation substrate was explored.We selected garden waste,peat and vermiculite as raw materials,mixed them in different proportions,and prepared six kinds of cultivation substrates.Taking Viola cornuta seedlings as test plants,pot experiments were conducted to study the differences in physical and chemical properties of the six kinds of cultivation substrates and their effects on the growth differences of Viola cornuta.The indexes were comprehensively compared by entropy weight coefficient and TOPSIS integrated comparison method,and the best cultivation substrate was selected.The results showed that with the increase of the proportion of garden waste compost,the pH value and EC value of the culture medium increased,and the bulk density and capillary porosity increased,which promoted the growth of Corydalis decumbens.To sum up,the best substrate formula is T3 treatment,that is,peat:garden waste compost:vermiculite=2:3:1,which can be used as an alternative substrate for the growth and cultivation of Viola cornuta.
