【摘要】 以滇西北丽江市拉市乡松口蘑(Tricholoma matsutake)产地为例,进行了松口蘑菌塘生态因子的调查。结果发现:(1)松口蘑菌塘多集群分布于狭窄的山脊及西南坡,坡面坡度在3060°之间,上层云南松荫蔽度0.40.6,下层高山栎、黄背栎等灌木丛荫蔽度达0.70.9,落叶层及腐质层16 cm;(2)出菇期间菌塘地表附近空气的平均温度14.1℃,平均相对湿度78.7%;(3)出菇期间菌塘的地下温度在15.020.5℃之间,西南坡的菌塘温度相对较高;(4)菌塘土壤的含水量比非菌塘土壤的含水量低,出菇期间平均低16.7%;(5)菌塘土pH约为5.5,比非菌塘土低7.9%;(6)菌塘土除全钾的含量比非菌塘土高之外,其余营养成分均比非菌塘的低。
【Abstract】 Ecological factors associated with Tricholoma matsutake shiroes(large contiguous areas of fungal mycelium growing on or under the surface of the soil) located in a mountainous area in Lashi,Lijiang,northwestern Yunnan Province,China,were investigated.Our data indicated that T.matsutake shiroes are usually distributed in clusters on the narrow mountain ridges and southern slopes(with a 30-60° incline),where the shading rates provided by the upper pine tree and the lower oak bush cover vary betwee...
