引言据大面积调查和水培试验诊断鳍果表明,引起山地柑桔黄叶枯梢病的直接原因,从营养角度分析有二种可能;一是缺硼,二是缺钙。这两种缺素的枯梢症状相似,但叶片发病部位和程度不同。现将山地柑桔缺硼原因以及防治措施的探讨结果阐述如下。
Introduction According to a large area survey and hydroponic experiments to diagnose the fin fruit, the direct cause of yellow leaf blight caused by mountain citrus is analyzed from the perspective of nutrition. There are two possibilities: one is boron deficiency and the other is calcium deficiency. The symptoms of the two kinds of deficiency are similar, but the incidence and extent of the leaves are different. The reasons for lack of boron in mountainous citrus and the prevention and control measures are described below.
