摘    要:以椴树,水曲柳、云杉和红松等树叶浸出液或土壤中混拌其叶粉等不同处理方法来培育云杉幼苗,研究这些树种对云杉生长的影响。实验表明,椴树和水曲柳等阔叶树对云杉幼苗具有明显的促进生长作用,而以云杉等针叶树的叶浸出液和叶粉培育的云杉,其生长较差。研究认为,橡树和水曲柳可作为培养人工云杉针阔混交林的重要搭配树种。

关 键 词:云杉  椴树  生长

Abstract:Picea koraiensis is one of main planting-tree species.In north easten China. Picea koraiensis forests are often mixed with such tree species as Tilia and Fraxinus.Hence study on the influence of main associated tree species on growth of Picea koraiensis is important not only for the tree allelopathy, but also for selection of properly associated tree in building mixed forest of Picea koraiensis. This paper deals with results obtained from a lot of experiments on culture of Picea koraiensis in flower pot using the extract of above mentioned trea leaves as well as their leaf powder mixed the soil. Experiment shows that leaves of Tilia and Fraxinus can step up increment of Picea koraiensis seedling height in comparison with Picea koraiensis and Picea koraiensis needle extract and power effect on that. Finally, Tilia and Fraxinus are suggested as important mixed trees in planting Picea Koraiensis coniferous-broadleaved forest.
Keywords:Picea koraiensis  Tilia atnvrensis  Fraxinu mandshurica  mutual influence
