We designed a system that can automatically collect, convey, and control cool air of 15oC-20oC containing carbon dioxide from a mushroom cultivation house to a strawberry plastic house. We recorded the temperature at various positions from July to August 2017. The average temperature of the green house during day and at night was maintained at 33oC and 26oC, respectively. In the moveable three-tier cylindrical bed, the average temperature around root was maintained at 26oC and 21oC during day and at night, respectively. On the high-bench in the green house, the temperature was maintained at 32oC and 30oC during day and at night, respectively. The carbon dioxide concentration was maintained around 800-1,600 ppm in the mushroom cultivation system and 400-800 ppm in the strawberry plastic house. The growth characteristics of the strawberry treated with moveable three-tier cylindrical bed were significantly different from those of the untreated high-bench bed. In addition, during the summer season, moveable three-tier cylindrical bed showed more tendency to increase in normal fruit number (NFN) and to decrease in defective fruit number (DFN) compare to the high-bench bed. Therefore, the moveable three-tier cylindrical bed showed a tendency to be more than 2 times higher yields than that of the high-bench bed. It was confirmed that everbearing strawberry cultivars could be cultivated in green house due to the cool air supply from the mushroom cultivation system in the summer season.
