【摘要】 通过八年调查分析得知，刺槐烂皮病的发生与雨季高温、多雨、大风、光照不良等气象因素有关，降雨量是主导因子；萌生林、纯林、郁闭度０．８以上及受害虫危害的林分发病严重；不同立地条件的林分发病情况明显不同，以土壤通透性差、易积水的山坡及阴坡风口处发病较重。更多还原

【Abstract】 The eight year investigation shows that the occurence of bark rot of Robinia Pseudoacacia is related to meterological factors including high temperature in rain season,heavy rainfall,strong wind,poor illumiation and so on.The rainfall is the main factor.The serious disease occurs in sprout forests,pure,insect infested stands and stands of canopy density over 0.8.The occurence degree differs evidently under different side conditions,The disease is more serious in followsing cases,in hillside with poorly aerated soil and wind gap in shade side.更多还原
