摘　　要：本文报道了稀土元素对酥梨叶片中氮、磷、钾含量,叶绿素含量及其光合效率的影响。结果表明,稀土元素有效地促进树体对氮、磷、钾的吸收。其中对磷的促进作用更显著。同时,增加了叶绿素含量,提高了光合强度。从而,提高了果实产量和品质。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.

关 键 词：稀土元素 酥梨 氮 磷 钾
