红托鹅膏生态环境研究

以武定狮山为样点,对红托鹅膏的生境进行了初步研究。结果表明,红托鹅膏主要生长于滇青冈、滇石栎等阔叶林或针（云南松）阔混交林中,其生长的土表层疏松、透气、潮湿,具有厚4 cm~9 cm的腐叶层,有稀薄的阳光透入,土层有机质含量高,矿物质养分丰富,土壤容重较小,偏微酸性（pH5.4~5.7）。子实体分化发育较适宜的温度为19℃~21℃,空气湿度为75%~86%,土壤含水量为38%~50%,并每天保证1 300 lx~2 000 lx的光照2 h~5 h,200 lx~900 lx的弱光6 h~9 h。

The Study on Ecological Environment of Amanita rubrovolvata

The ecological environment of Amanita rubrovolvata of Mountain Lion of Wuding of Yunnan was studied in the paper.The results showed that A.rubrovolvata mainly grew in road-leaf forest of Cyclobalanopsis glaucoides and Querus franchetii.It＇s optimum growth soil was lax,gas permeable and moist with 4 cm～9 cm thicker rotten leaves and with scattered light,higher organic matter content,abundant mineral element,lower volume weight of soil,pH 5.4～5.7.The optimum temperature,air humidity,water content of soil,light intensity on the growth and developmen of fruiting body were 19℃～21℃,75%～86%,38%～50%,1 300 lx～2 000 lx（2 h～5 h） and 200 lx～900 lx（6 h～9 h）,respectively.
