In order to cultivate high yield with good quality Ginkgo biloba leaf-producing plantation, coppice management of 1,2,3-year -old Dafuzhi seedling at different stump heights (or top bud pruning) were take n and some physiological and biochemical indexes and yield of Ginkgo biloba leaves were determined on May 15 and September 11. The results showed that the c hlorophyll content, net photosynthetic rate, transpiration rate and water conten ts of all treatments and the total flavonoid concentration of some treatments we re higher than those of CK; Leaf yield and total flavonoid yield per plant of so me treatments were higher than those of CK at the later stage of the year.
