摘要
于2003—09～2004—06在陕西杨凌、周至、礼泉、淳化、黄陵等地，对苹果树腐烂病的发生情况，以及危害的严重程度进行了初步调查。结果显示，树龄与苹果树腐烂病的发生直接相关，表现为随着树龄的增加腐烂病危害逐渐加重。地区之间苹果树腐烂病严重程度存在着不同程度的差异，除地区间小气候外．管理水平也是影响腐烂病发生的重要因素。
The authors investigated the occurence of apple tree valsa canker at YangLing,Zhouzhi,LiQuan,ChunHua,HuangLing,and some other places from September of 2003 to June of 2004. The result shows that there is a close relation between the age of the apple tree and the disease index. With the apple tree age increases ,the diseased tree rate has a raising trend.
