红托鹅膏生态环境研究

The Study on Ecological Environment of Amanita rubrovolvata

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 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.
