摘　　要：分析4种不同复配基质的理化性质和4种基质栽培的3种常用立体绿化植物的生长情况,探讨适合模块式立体绿化的基质配比,为模块式立体绿化的基质筛选提供可靠的依据。结果表明,T 3配方的基质(泥炭∶松树皮∶有机肥6∶2∶2)在饱和容重、总孔隙度、持水性、通气性等性状上比较理想,有机质含量和CEC值在合理的范围内且含量较高,表明该基质配方能够持续地为植物生长提供养分的潜力比较强。在T 3配方基质栽培的3种植物小蚌兰(Tradescantia spathacea)、鸭脚木(Heptapleurum heptaphyllum)、红檵木(Loropetalum chinense var.Rubrum)生长健壮且生长速度适中,符合模块式立体绿化对基质的要求,可适当提高基质的pH,以满足更多植物的需求。The physicochemical properties of 4 different complex substrates and the growth conditions of 3 common three-dimensional greening plants under 4 matrix ratios were analyzed,and the matrix ratio suitable for modular three-dimensional greening was discussed,which provided reliable basis for matrix screening.The results showed that the matrix of T 3 formulation(peat:pine bark:organic fertilizer 6:2:2)was ideal in saturated wet bulk density,total porosity,water holding capacity and air permeability,and the content of organic matter and CEC was relatively high and within a reasonable range,which indicated that the formulation had a strong potential to provide nutrients for plant growth continuously.Tradescantia spathacea,Heptapleurum heptaphyllum,Loropetalum chinense var.Rubrum grew robustly and at moderate growth rate in the T 3 formula matrix,which met the requirements of modular three-dimensional greening on the matrix,and the pH value of the matrix could be increased appropriately to meet the needs of more plants.
