| The quality of oak mushoom(Lentinus edodes(Berk) Sing) is sensitively affected by environmental factors, especially moisture by the rain during the growing period. To protect mushrooms from being wet, plastic-covered facilities with side openings are mostly being used. However, the indoor temperature and humidity f the facility without roof opening become higher due to its poor ventilation, and consequently reduce the productivity and quality as well. In this study, we analyzed the ventilation rates and indoor temperatures of improved facilities as affected by the area of roof opening and shading rate by the model. The indoor temperature decreased by more than 2.5$^{circ}C$ as the shading rate increased from 50% to 90%, and especially the effect of wind speed on indoor temperature was significantly great under as low as 50% of shading rate. The ventilation rate became higher under wind speed of 1~2m.s-1 regardless of the shading rate. As the wind speed increased from 0m.s-1 to 2m.s-1, the indoor temperature decreased by more than 2.$0^{circ}C$. Moreover, the indoor temperature became lower with increasing roof opening ratio, but showed no significant differences at more than 50% of roof opening ratio. At lower shading rate, the indoor temperature sensitively decreased with increasing area of roof opening. Additionally, we obtained the higher ventilation performance with the area of roof opening more or less equal to side opening, regardless of the wind speed and shading rate. |
