ABSTRACT
.<b><sc>Abstract.</sc></b> In this study, Growing spot heating system for the high-bed strawberries was composed of air source heat pump(3.8RT) in type to water, thermal storage tank (3m<sup>3</sup>), temperature control device and growing pipe. The experiment conducted by comparing with crown(growing part) + space 5℃(treatment 1), root zone 5℃ (treatment 2) 10℃ (control). 3 greenhouses covering material polyester plastic film monolayer area 210m<sup>2</sup> per one greenhouse. addition, four rows high-beds were built each greenhouse, korean domestic strawberry cultivar "Seolhyang" cultivated From November 7, 2017 March 31, 2018. yield energy consumption treatment examined. For crown zone, water maintained at 35°C using an pump, surface hot pipe 20°C, As a result comparison test, 1 increased 22% compared 2 11% control. Moreover, reduced 58% that 52%
