In northern China, cool-season grasses are mostly used for lawn greening, such as Kentucky bluegrass, tall fescue and perennial ryegrass. Because of their drought resistance and excellent trampling resistance, these grasses are mostly used in fairway lawns of golf courses. In southern China, warm-season grass species are mostly used as lawn greening grass, such as dog tooth grass and Zoysia japonica. These grasses are fine in texture, good in elasticity and strong in green, and are widely used in parks and various sports venues. They are the dominant grass species in southern China and are favored by people.
