- Abstract:
- The paper discussed the freezing-thawing condition of main dryland farming soil areas in northeast China, annual mean temperature, January temperature, days of temperatures below 0℃, annual temperature range, temperature rising in spring was used to analyze the impact on freezing-thawing function. The results showed: the above factors have great impact of phaeozem, less impact of chernozem and white pulp soil, least impact of brown soil and cinnamon; annual mean precipitation, post-autumn precipitation was used to analyze the impact on freezing-thawing function, the results showed: the above factors have great impact on freezing-thawing function of brown soil, less impact of phaeozem and white pulp soil, least impact of chernozem and cinnamon. Meadow soil is distributed widely, these factors are different with the latitude difference.
