用 PBOG、瑞丰钾大量元素水溶肥料、五洲绿世界（高钙）、含海藻酸水溶肥料、99%含量KH2PO4等5种叶面肥，对次郎甜柿叶面施肥的试验结果表明：喷施叶面肥均有明显增强树势的效果，分别较不喷肥的对照处理产量提高24.9%、19.7%、14.4%、30.9%和15.2%；果实可溶性固形物含量较对照略高，但果实品质差异不显著。其中，喷施含海藻酸水溶肥料处理增产最高，但果肉硬度略低于对照和其它处理，固形物含量亦低于其它4种叶面肥处理。

Five foliage fertilizers, PBOG, Russian potassium fertilizer, Transworld Green (high calcium), algal acid solu-tion and KH2PO4 (containing 99% ), have been tested on Jiro persimmon. All fertilizers have effect on yield, in-creased by 24.9%、19.7%、14.4%、30.9%and 15.2%respectively than control. The content of soluble solid is higher than con-trol, but there is no obvious difference in fruit quality. Furthermore, the yield would reach to the highest after spraying al-gal acid containing solution, while its fruit hardness is lower than that of control and the other fertilizers, so does its solid con-tent.
