| 摘 要： | 杉木（Ｃｕｎｎｉｎｇｈａｍｉａ ｌａｎｃｅｏｌａｔａ）与主要阔叶造林树种叶凋落物混合分解实验是用网袋法进行的。目的是检验“杉木叶凋落物与阔叶凋落物混合分解时，杉木叶凋落物的分解速率和养分释放都可得到加强”这样一个假设。结果发现，杉木与火力楠（Ｍｉｃｈｅｌｉａ ｍａｃｃｌｕｒｅｉ ｖａｒ．ｓｕｂａｌａｎｅａ）、桤木（Ａｌｎｕｓ ｃｒｅｍａｓｔｏｇｙｎｅ）叶凋落物混合分解时分解速率有较强的促进作用，而

| Abstract: | Decomposition of Chinese fir leaf litter when co occurring with broad leaved species Michelia macclurei var. sublanea, Alnus cremastogyne, Schima superba, Kalopanax pictus, Castanopsis hystrix and Cinnamomum camphora was examined using litter bag method to test the hypothesis that decomposition of Chinese fir leaf litter could be accelerated by the presence of broad leaved litter. Weight loss rate of Chinese fir was increased significantly by M. macclurei var. sublanea, A. cremastogyne, but not by S. superba, K. pictus, Castanopsis hytrix or Cinnamomum camphora. The nutrient release was enhanced to different degrees by litter of all broad leaved leaf species with the exception of S. superba which had no effect. With increasing initial nitrogen concentration of broad leaved leaf litter, the larger the enhancement. A. cremastogyne was the first choice as the companion species in the mixed plantations of Chinese fir, secondly K. pictus, thirdly M. macclurei and Castanopsis hystrix ,and lastly Cinnamomum camphora and Schima superba. |
