<正>通过３２块典型样地的调查、分析，数据经不同方法处理结果表明：毛竹枯梢病（ＣｅｒａｔｏｓｐｈａｅｒｉａｐｈｙｌｏｓｔａｃｈｙｄｉｓＺｈａｎｇ）的发生随土壤紧实度的增大、土壤湿度的下降而感病程度加重；对土壤养分含量的分析表明：枯梢病的发生与林地养分含量的多少关系密切，其发病程度与土壤全氮和速效磷含量呈极显著的负相关，与土壤钾和硼水平的交互作用呈显著负相关，土壤中过多的活性铁可助长病害的发生。改善感病竹林地土壤的理化性质是综合治理该病的一个关键环节。

The result of the investigation of Mao bamboo forest on 32 typical plots distributed in Fujian implicated that the genesis of dieback blight of phyllostachys pubescens might have been influenced by losing soil fertility, deteriorating soil physical and chemical properties in extensive management of bamboo land before. According to the results of simple correlation analysis and multiple regression analysis, the genesis severity of Mao bamboo dieback blight had a highly significant negative correlation to the amount of total N and available P,a significant positive correlation to the available fe, and a significant negative correlation to the mutual effect of available K and B in the soils. In addition, the results also indicated the disease incidence was increased along with higher consistency and lower humidity of the soils as well.
