| 摘 要： | ‘梨红叶枯萎病’是湖北省一些碱性沙土梨园近年来出现的一种病害,受害梨树整株死亡,成片毁园,经研究证明此系缺硼引起。但梨树的需硼范围甚小,适宜的土壤速效硼含量指标大致为0.14～0.55×10~(-6),梨叶含硼指标,约为21～47×10~(-5)。施用不当,常会引起硼毒为害。

| Abstract: | Red leaf and shoot dieback in pear is a new problem in commercial pear production in the alkaline soil in Hubei province. It can kill the pear trees and finally destroy the whole yard. It showed that it is caused by boron deficiency. It was found also that the range of suitable boron concentration in pear tree is quite narrow,which is about 0.14～0.55×10~(-6) in soil and about 21～47×10~(-6) in the leaves. |
