摘要:
采用尼龙分解袋的方法，对四川岷江上游地区连香树、云南松、糙皮桦和云杉4种典型人工林凋落叶进行田间混合分解试验。结果表明，糙皮桦与云杉、糙皮桦与云南松、连香树与云南松凋落叶混合后对分解有明显的促进作用，而连香树与云杉凋落叶的混合对分解的促进作用不明显。此外，放置在阔叶林地的针阔混合凋落叶分解速率较之放置在针叶林地的快，证明阔叶林地环境有利于凋落叶的分解。因此得出营造云南松和糙皮桦、云南松和连香树、云杉和糙皮桦混交林来改善凋落叶分解状况及土壤肥力、防止纯林造成的土壤极化是可行的。第2期张丽萍等不同森林凋落叶混合分解试验研究
Abstract:
Decomposition of mixed foliar litters from the four typical plantitions in upper reaches the of the Minjiang River was studied by using the litterbag method. It was found that mixture foliar litters of Picea asperata and Betula utilis, Pinus yunnanensis and B. utilis, Cercidiphyllum japonicum and P. yunnanensis showed obvious positive interaction to decomposition, obserred in those of P. asperata and C. japonicum there was no unconspicuous interaction. Furthermore, the same mixed foliar litters in broadleaved forest stand decomposed fast compared with pine forest stand. It is proved that broadleaved forest stand was propitious to the decomposition of foliar litters. So aforestation of mixture of P. yunnanensis and B. utilis , P. yunnanensis and C. japonicum , P. yunnanensis and B. utilis could improve the decomposition of foliar litters and the soil fertility, prevent the soil polarization of the pure forest.
