The invention relates to the technical field of grape planting, and relates to grape culture soil. The grape culture soil comprises river sand, gravel, vegetable garden soil, modified coal cinder, pinewood sawdust, mountain clay, medical stone particles, limestone and fertilizer. The grape culture soil is good in physical and chemical properties and has very good breathability and a high fertilizer-retention and water-retention capability, by using the grape culture soil, soil hardening can be well improved, the content of soil organic matter is increased, mineral nutrients are increased, and comprehensive adsorption of nutrients and water in the grape growth process is promoted; by using the grape culture soil, the acid and alkali environment of soil needed for the grape growth can be well maintained, the salinization of the soil is eliminated, the utilization rate of the nutrients in the planting soil for the grape growth is increased, the color and the sugar degree of grape fruits are increased, the mouthfeel of the grape fruits is improved, the yield of the grape fruits is increased, the content of anthocyanin in grapes can be increased through the grape culture soil, and the quality of the grapes is improved.
