| Abstract: | Suli (P.bretschneideri Rehd) were sprayed with rare earth elements,Results showed:Rare earth elements could stimulate the absorption of N.P.K.by the plant.The net photosynthetic rare of the leaves were significantlyincreased during the grewing period of the shoot.But the net photosyntheticrate of the leaves were not increased during the flowering period. |
