초록

We conducted a study on the possibility of using the power plant's thermal effluent system by using a heating system to utilize the thermal effluent from Jeju Power Headquarters of KOMIPO. In this study, growth information such as the size, leaf area, fresh weight and dry weight of subtropical persimmon fruit (A) in the facility cultivation complex were measured. In the comparison group (B), the growth information of the same crop was measured and compared in an unheated greenhouse near Harye-ri, Namwon-eup, Seogwipo. Fruit size was measured at monthly intervals, and leaf area, fresh weight, and dry weight were measured at new shoot season. Measurement results of A and B growth information, 1) Fruit diameter & length, A grew 7.3% and 9.4% than B, 2) Leaf area, A grew 4.7% than B, 3) Fresh weight, the decrease was 8.9%, but the dry weight was 3.6%, indicating that A contains more nutrients than B. Therefore, if the heating control by supplying thermal effluent to the facility greenhouse, it can contribute to reducing the energy cost and improving quality.
