36. Clover use in China: Barenbrug - China FANG Lining FANG Lining – conferred with national experts  White and red clover are the most important clover species used in China.  Use of white clover far exceeds that of red clover.  Crimson clover was introduced when price was low, but with higher cost, use has been discontinued.  There has been some testing of strawberry clover, but no market has been established.  Farmers use vetches and beans in hotter parts of southern China.  White and red clovers: Used in Southwest, Northeast and middle China. Grows well in Yunnan, Guizhou, Sichuan, Guangxi, Hunan, and Jiangsu provinces.  Both used for forage-livestock systems.  White clover is also used for landscape applications in both northern and southern China.  Xi’an and Yangtze River watershed are important tourist areas with large beautification budgets.
