Study on Temperature Variation by Greenhouse Soil Warming System Using Solar Thermal Energy (3) - Verification Experiment on Commercialization of Cultivation

According to the result of the first report and the second report of this study, it was expected that soil heating in a protected cultivation in winter season would affect the initial growth and development of fruit. Based on the result of previous study, we compared height, leaf number, leaf area,...

Summary:According to the result of the first report and the second report of this study, it was expected that soil heating in a protected cultivation in winter season would affect the initial growth and development of fruit. Based on the result of previous study, we compared height, leaf number, leaf area, fruit weight, crop growth rate (CGR), features and quantity of cucumber for 3 months after planting between the soil heating group and the non-heating group. The result were summarized as follows: The height, leaf number, leaf area and fruit weight of cucumber in the soil heating group were 12.5%, 14.6%, 21.4% and 22.8% higher, respectively, compared to those of cucumber in the non-heating group. Although both the soil heating group and the non-heating group similarly showed an increasing pattern in CGR after transplanting, the soil heating group showed the increased CGR by 12.1% compared to that of the non-heating group. The quantity of cucumber in the soil heating group was about 26% higher than that of the non-heating group. It is assumed that the activation of initial growth and development of fruit in the heating group resulted in the increase of quantity.
