摘要
采用样方调查方法,对泡核桃溃疡病的立地条件影响因素进行了调查分析。结果表明,坡向和坡度对泡核桃溃疡病的发生有显著影响,其中阳坡的泡核桃树发病最轻,阴坡的发病最重,病情指数分别为23和46;陡坡的泡核桃树发病最重,平坡的发病最轻,病情指数分别为48和19。
The influencing factors of site conditions on Canker disease of Juglans sigillata Dode were studied by using sampling method. The results showed that site condition of slope aspeets and gradient have significant influence on Canker disease of Juglans sigillata Dode. The Canker disease attack is the lowest at sunny slope but the highest at Shade slope, and the disease oecurred index are 23, 46 respectively; The Canker disease attack is the highest at steep slope but the lowest at flat slope, and the disease index are 48, 19 respectively.
