In the present paper, based on a 4-year ecological observation of Russula vinosaLindbl, its ecological environment was investigated in order to simulate its ecological environment when they are cultivated. The result shows: R. vinosa is a kind of ecotomycorrhizal fungi. R. vinosa emerged and developed in the relatively steady ecological environment where average temperature, humidity and soil water content were 25-2℃, 80 %-100 % and 40 %, respectively. Among the three environmental factors, soil water conte...
