摘　　要：以"博耐13号"黄瓜为试材,运用土壤热通量板及常规气象数据观测,对不同天气的黄瓜土壤热通量进行了研究。结果表明:在阴天,土壤相对含水量50%～60%和土壤相对含水量75%～90%水分处理的黄瓜土壤热通量基本没有太大的变化,均表现为放热过程;在晴天,2个水分处理的土壤热通量呈相反变化趋势,土壤相对含水量50%～60%处理的土壤热通量为热汇-热源-热汇变化,土壤相对含水量75%～90%水分处理为热源-热汇-热源变化。＇Bonai No. 13＇cucumber was used as test material, soil heat flux plates and routine observing systems of gradient weather were used to determine characteristics of soil heat flux in cucumber under different weather conditions. The results showed that all the soil heat fluxes was similar, all showed an exothermic process in cloudy weather. But in sunny days, the two water treatments of soil heat flux showed the opposite trend. Relative soil water content 50%-60% for the treatment of the soil heat flux heat sink-heat-heat sink changes, relative soil water content 75% -90% of water treatment as the heat source-heat sink-heat changes.
