浙江天童常绿阔叶林马尾松菌根研究

Research on the Mycorrhiza Fungi of Pinus massoniana Lamb.Evergreen Broad-leaved Forest in Tiantong,Zhejiang Province

对浙江天童常绿阔叶林马尾松菌根进行了研究,分析了马尾松在不同样地以及不同季节菌根的感染率.结果表明:在温度低、气候干燥、土壤贫瘠的环境下,菌根感染率较低,而在温度高、气候湿润、土壤肥沃的环境下,菌根感染率较高;在调查中发现,与马尾松共生的菌根真菌有4科6属8种,其中硬皮马勃科Scleroderm ataceae的彩色豆马勃P isolithus tinctor ius(P ers.)和大包硬皮马勃S clerod erm a bov ista F r.以及红菇科Russu lacese的松乳菇L acta r ius d eliciosus(L.ex.F r)G ery分布较广泛,在多数样地中均可找到相应的子实体;通过菌根在生态系统中的作用,初步探讨了菌根与常绿阔叶林整体退化机制之间的关系.

This article mainly researches on the mycorrhiza fungi of Pinus massoniana Lamb. evergreen broad-leaved forest in Tiantong, Zhejiang Province. The effect of mycorrhiza fungi on Pinus massoniana Lamb. is different in different seasons and regions, especially when the qualities and species are different. The results show as follows. Firstly, average infection rate is higher in the condition of high temperature, humid climate and fertile soil than that in tow temperature, dry climate and poor soil. Secondly. there are 8 species of myeorrhiza fungi that accrete with Pinus massoniana Lamb. in the forest which we researched on; they belong to 6 genus and 4 families; distributioo of P. tinctorius （Pers.）, S. bovista Fr and L. deliciosus （L. ex. Fr） Gery are wider than other species; and their fungus can be found in most regions. Finally, based on the effect of mycorrhiza on the ecology system, the paper primarily discusses the relations between myeorrhiza and the degradation of evergreen broad-leaved forest.
