The invention relates to a sand-stabilization culture method for outdoor grapes. The method comprises the following steps: 1, digging planting furrows, wherein the directions of the planting furrows are set in the east-west direction, the spacing between the planting furrows is determined according to grape varieties, and reserving the digged topsoil 20 minus 5 to 20 plus 5 cm below the ground for later use; 2, refilling the planting furrows; 3, planting the grapes, planting grape plants in the middle positions inside the planting furrows with two rows; 4, setting a south slope and a north slope of a small sunny slope; 5, intercropping grass species which have the characteristics of drought resistance, cold resistance, shade resistance, and trample resistance among planting furrows; 6, after the outdoor grapes are harvested in autumn, placing main vines into the planting furrows in the direction of the planting furrows, and covering glue-sprayed cotton quilts for overwintering and proofing cold or 30 minus 5 to 30 plus 5 cm corn straw black adding film on the main vines. By adopting the method provided by the invention, the traditional culture trellis for the outdoor grapes is changed, the yield per unit area of a grapery can be greatly improved, and the soil wind erosion caused in the culture process of the outdoor grapes can be effectively reduced.
