摘要： The Southern China karst area that represented the most typical tropical-subtropical karst in the world showed serious desertification. The grape cultivar 'Yeniang No.2' was a variant with high drought resistance that we selected from Vitis quinquangularis. 'Yeniang No. 2' was planted in containers with desertified soil of a karst region, and treated with a range of levels of irrigation, nitrogen (N), phosphorous (P) and potassium (K). After four years, soil pH decreased, soil organic matter and soil available N, P, and K increased. Therefore, local farmers could plant "Yeniang No. 2" at the foot of karst mountains or on lower elevation mountains to improve the environment and earn income. The highest fruit yield was 73.64 kg/vine when P=2.674 g/vine, and K=2.15 g/vine. The reasonable combination could significantly increase soil fertility in the karst area and save money for local farmers.
