五种叶面肥对次郎甜柿产量和品质影响的试验

The Effect of Five Foliage Fertilizers on Yield and Quality of Jiro Persimmon

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.
