Abstract/Contents:"Experiments were conducted to investigate the soil freezing depth and pattern with freezing measuring instruments during 1988-89 winter season in Kangwon province. Freezing measuring instrument was made with acrylic pipes which were consisted of inner and outer parts. Inner pipe was filled with 0.01% methylene blue solution and rubber hose to protect pipe breakdown by solution freezing. Freezing measurements were carried out by observing discoloration of methylene blue solution. Moisture content of evergreeen trees and ground cover plants was also examined in the winter season. The observed results are as follows: 1. In the land of 100M above sea level, soil freezing depth became deeper as the sum of Accumulated degree-days of temperature below 0°C(O°C/day) increased: Soil freezing depth was 30-40cm at 100°C, 42-43cm at 150°C, and 47cm at 200°C/day 2. Soil freezing with vinyl mulching was less developed by 13cm at 100°C with sum of subzero temperature, by 17cm at 200°C than that of bare ground. Soil of rich hulls mulching with 40cn was not frozen until soil freezing at the bare ground was developed to 25cm depth. 3. Cashmeron mulching was more effective than felt mulching in the heat insulation of soil. 4. Thawing of soil was done from the lowest part of the frozen in the ground to upward in the beginning and after that it was done from the surface of frozen soil to downward. Finally thawing was completed at the middle of frozen soil."
