| Abstract/Contents: | "Experiments were conducted to investigate the relationship between the soil freezing depth and the accumulated degree-day of temperature below 0°C at 17 locations during 1989-1990 winter season in Kangwon province. The observed results are as follows: 1. When accumulated degree-day of temperature below 0°C was 141°C at late January, soil freezing depth of sunny place was 46.5cm , that of shaded lot was 59cm, and that of marginal place sunny or shaded area was 55cm, in Chun cheon. 2. Accumulated degree-day of temperature below 0°C of Dae gwangryong area was more than that of Un-du, whereas soil freezing depth of Daegwangryong was lower than that of Un-du. It was considered that snow covering worked as heat insulator. 3. Soil freezing depth of vinyl mulching on Zoysia turf was less by around 20cm than that of non-vinyl mulching. Rice hulls covering of 40cm showed the great heat insulation effects with the soil freezing depth of 1.5cm at sunny place and 6.5cm at shaded lot compared to that of 47cm at sunny and 59.5cm at shaded place bare ground. 4. Among investigated areas, Dunae, Honeg seong gun was the deepest soil freezing, 89cm with 569°C of accumulated degree day of temperature below 0°C at late February. 5. dehydration of Juniperus C. var. Kaizuca, Euonymus japonica, and Chamaecyparis pisifira at winter season was around 5%, however dehydration of Vinca minor was more than 10%." |
