Abstract

The results were as follows; 3 additives(rice bran, wheat bran and soybean bran) to the Quercus dentata sawdust were applied at 10, 20 and 30%. High yield was recorded at 20% of rice bran and wheat bran and 30% of soybean bran. Among various sawdust media, the cultivation with the Quercus dentata sawdust alone showed the most favored growth index, such as 22 days of full mycelial growth, 11 days of pinheading from spawning and 23.5g per $1,200m{\ell}$ bottle. In the size of bottles, the lowest infection ratio was 5 % at $1,200m{\ell}$ bottle. In the growth characteristics with the bottle size, Reishi at $1,600m{\ell}$ bottle showed best result when it is observed for 13~15 days in pinheading from spawing, 36~37 days in fruit bodies growing and 26.7~29.3g yield per bottle. The highest yield per area was 6.4kg at horizontal bed with 218 bottles per $3.3m^2$. The Reishi produced in $1,600m{\ell}$ bottle with horizontal cultivation had less number of fruit bodies and best yield, thus it is determined to be the most economic method.
