This study was carried out to investigate the management characteristics and techniques by comparing and analyzing the process of mixing, sterilization, cooling, inoculation and incubation for bag cultivation of L. edodes. The medium was sterilized after mixing it for 30 minutes, 1 and 2 hours respectively. The general moisture content of the sawdust substrate has been adjusted to 65%, while the case of the L. edodes substrate was 55%. Only 5% of wood chips of 5-8 mm in particle size were mixed to secure the space of the sawdust particles. As a result, mycelial growth was 1.4cm faster and the density was better(+++) than control(++). Wood chips are soaked in advance for a week during winter and 4 days during summer. There is an average number of 1.6x108 (cfu) of microorganisms in the sawdust that has been piled for six months outdoor. In summer, it has to be used immediately after mixing sawdust. High-pressure sterilization should be performed to use as a mushroom spawn, and to improve physical properties, it was great to sterilize the medium at a normal-pressure. There are height and width type for bags to be consumed for bagging. When the height was reduced into 17cm and the width was increased into 13cm, the browning period was shortened by 30 days and the period of mycelial growth was shortened by 25 days. The sterilized medium had an average of 4x103(cfu) of microorganisms at 25°C and 1.3×102 (cfu) at 15°C. After 25 days from inoculation in vitro, the growth condition of sawdust was the best with 13.2 cm, followed by grain spawn and liquid respectively. When inoculated with liquid spawn, the moisture content of substrate should be adjusted to 55% to 50% in advance.
