| 摘 要： | 经2002～2003年盆栽试验观察,粗皮病的发生与土壤高锰含量有直接关系.施锰300mg/kg以下树体生长发育正常,施锰350 mg/kg前期上部枝少部分幼叶出现失绿现象,施锰400mg/kg以上树体发生粗皮病.施锰400mg/kg叶片锰最高值为890 mg/kg,是施锰350 mg/kg的3.1倍,土壤有效锰、易还原锰、交换锰含量最高值分别是施锰350 mg/kg的1.1、2.3、22.0倍.说明土壤高量的易还原锰、代换锰是粗皮病发生的重要因素.施锰发病后土壤铁、硅的含量降低,磷、钾的含量提高. |

| Abstract: | The happening of Internal bark necrosis related directly with high content of Mn in soil under pot experiments during 2002 to 2003.Trees grew well with Mn content below 350mg/kg,while Internal bark necrosis appeared with Mn content above 400mg/kg.The highest Mn in leaf is 890mg/kg under the treatment of 400mg/kg,which is as much as 3.1 times than the treatment of 350mg/kg.The highest contents of effective Mn,reductive Mn and exchangeable Mn in soil is 1.05,2.28,21.96 times than those in the treatment of Mn 350 mg/kg.This indicated that high amount of reductive Mn,exchangeable Mn is crucial factor for the happening of Internal bark necrosis.Contents of Fe and Si decreased in soil while p and k improved after Mn application. |
