【中文摘要】 本文报道昆明小哨和宜良竹山两地区两种植被类型和两种成土母质发育的土壤上，干巴菌根际上壤理化性质的研究。实验分析表明：（１）干巴菌只能在弱酸性的沉积岩尖（石灰岩或砂页岩）或河流沉积物类成土母质发育形成的山原红壤的针叶林型的云南松或阔叶林型的麻标林下生长发育。而其它成土母质形成的土壤中云南松林或麻烁林下，不会长出干巴菌。（２）干巴菌根际土壤必须具有良好的理化性质──土壤政松多孔、透水透气和土温传递优良；ｐＨ值在４．５～５．５区间内；土质富含钙和铁，特别是钾的含量更高。（３）干巴菌生长环境，对大气湿度要求较严，相对湿度必须在７６％以上。（４）干巴菌子实体内合有３％植被的凋落物，植认及其残落物与干巴菌的化学组成相似。（５）干巴菌是一种富合钙、铁、钾而少磷的大型真菌。
【英文摘要】 This parper reported the vegetation and the physical-chemical nature of Thelephoraganbajun's rhizosphere soil at Xiaoshao, Kunming and Zhusan, Yiliang. The experimental analyses showed:1.Thelephora ganbajun only is found under the forest of Pinus yunnanensis or Quercus sp. which grow onplateaus red soil that the weak acid sedimetary rock(Lime rock or sand rock) or river sedimentary substanceformated.T. ganbajun do not be found under the forest of Pinus yunnanensis or Quercus sp. which grow onother kinds of soil; 2. The soil on which grows possesed good physical-chemical nature,such as loose,much porous,fine air-water permeability and good transmision of temperature. The soil pH is 4.5～5.5and rich in Ca,Fe and K,especially the concentration of K is high;3.The growth of T. ganbajun has strictlimitation of humidity,the relative humidity is above 76%;4. There is 3 percent humus of vegetation in thetissue of T. ganbajun,the chemical component of humus is as same as T. ganbajun's;5. The chem...更多ical com-ponent of T. ganbajun's tissue is rich in K, Ca and Fe but less P. 还原
