초록

Experiments of local cooling and heating on crown and root zone of forcing cultivation of strawberry ‘Seolhyang’ using heat pump and root pruning before planting were conducted. During the daytime, the crown surface temperature of the crown local cooling treatment was maintained at 18 ~ 22oC. This is suitable for flower differentiation, while those of control and root zone local cooling treatment were above 30oC. Budding rate of first flower clusters and initial yields were in the order of crown local cooling, root zone local cooling and control in root pruning plantlet and non pruning plantlet, except for purchase plantlet. Those of root pruning plantlet were higher than those of non pruning plantlet. These trends were evident in the yield of the first flower cluster until February 14, 2018, and the effect of local cooling and root pruning decreased from March 9, 2018. The budding rates of the second flower cluster according to the local cooling and root pruning treatments were not noticeable compared to first flower cluster but showed the same tendency as that of first flower cluster. In the heating experiment, root zone local heating(root zone 20oC+inside greenhouse 5oC) and crown local heating(crown 20oC+inside greenhouse 5oC) saved 59% and 65% of heating fuel, respectively, compared to control(inside greenhouse 9oC). Considering the electric power consumption according to the heat pump operation, the heating costs were reduced by 55% and 61%, respectively.
