| 摘 要： | 调查并分析了安徽省宁国市不同种植区山核桃溃疡病与土壤因子、树皮中营养元素等之间的关系,结果表明:山核桃林分中土壤条件与溃疡病的发生与发展的关系十分密切,其感病指数与土壤密度,树皮中P、Fe的含量呈正相关关系;与土层深度,土壤中N、P、K元素的含量和土壤中有机质的含量及树皮中N、K、M g的含量等呈负相关关系。

| Abstract: | Relationship between soil factors,nutrition elements in bark and canker of Carya cathayensis was researched in Ningguo City of Anhui Province.The results indicated that infection and spread of canker was in great relation with the condition of soil in C.cathayensis forest.There was positive correlation between infection index and soil density or contents of P and Fe in bark;there was negative correlation between infection index and soil depth,contents of N,P,K and organic matters in soil,or contents of N,P and Mg in bark. |
