Abstract: Vegetation concrete is widely used in ecological restoration of exposed slopes at present. Different soil types have great differences in substrate strength and water retention, which affects plant growth. The essence of different soils is the difference of soil particle gradation, where sand particles form a skeleton with coarse particles, and fine particles are filled and bonded. Indoor maintenance and outdoor potted plants were combined to explore the effects of soil quality (silty sand, low liquid limit silty soil and low liquid limit clay) on the physical and chemical properties of vegetation concrete and the growth of ryegrass. The results showed that the permeability coefficient was positively correlated with large pore size and total porosity, and also related to cement hydration. Saturated water content was positively correlated with total porosity and capillary porosity. Water evaporation rate was negatively correlated with capillary porosity and water content, and cohesion was related to gradation and cement cementation. The internal friction angle was positively correlated with coarse particles, which was related to roundness and cement hydration. Nitrate content and nitrate leaching rate were related to capillary pores and substrate compactness. Ammonium nitrogen content and ammonium nitrogen leaching rate were related to capillary pores and clay content. The polarizing microscope was used to explain the reasons why different soil properties affected the macro-characteristics of vegetation concrete from the perspective of meso-structure. Based on the above index analysis and practical experience, it was concluded that vegetation concrete made of silty sand was more conducive to plant growth, and all the indexes were within the acceptable range.
