摘要
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 taken 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 chlorophyll content, net photosynthetic rate, transpiration rate and water contents of all treatments and the total flavonoid concentration of some treatments were higher than those of CK; Leaf yield and total flavonoid yield per plant of some treatments were higher than those of CK at the later stage of the year.
