摘　　要：土壤热量状况对植物的生长、养分的转化等有重要的影响,与植物根系生长有密切的关系,土壤温度是衡量土壤热量状况的主要因素。研究表明,土壤温度和环境因子关系密切,与环境温度有直接的关系,随着深度增加,这种相关性减弱。Soil heat regime is important to the growth of Gingseng root system and the nutrition conversion. The soil temperature is major index to judge soil quantity of heat regime. Research indicated that the soil temperature was directly related to the environmental temperature, and the relativity weakened with the depth of the soil.
