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.展开更多
