Disclosed is a method for overwintering and cold resistance of grapevines, the vines are covered with a biological solidification layer, and the method includes the following steps: placing stems of the vines in rows on a ground, and digging soil between the rows to cover the vines and stems in the rows to form a soil-covered layer; and a thickness of the soil-covered layer is such that a distance from the stems to a top of the soil-covered layer is 50-100 mm; and spraying biological solidification solution onto the soil-covered layer to form the biological solidification layer, where composition and concentration of the biological solidification solution are as follows: 0.5-2 g/L of bean flour, 0.2-1 g/L of xanthan gum, 0.2-1 g/L of cellulose, 0.5-2 g/L of urea and 0.5-2 g/L of calcium chloride. The method is safe, reliable, time-saving, and easy to operate for overwintering of vines.
