温室内土壤热量垂直通量及其对土壤热状况的影响

THE SOIL VERTICAL HEAT FLUX AND ITS EFFECT ON SOIL HEAT CONDITION IN SUNBEAM GREENHOUSE

根据日光温室内外土壤温度的实测资料，计算了温室内外土壤热量垂直通量的平均日变化；利用热量平衡方程探讨了温室内土壤的增温效应，为推广和应用温室蔬菜栽培技术提供科学依据。

According observational data of soil temperature. Mean daily variation of the soil vertical heat flux has been calculated in and outside sunbeam greenhouse. By equation of heat balance, heating effect of soil in greenhouse has been studied. Scientific basis have been provided to popularize and use greenhouse vegetable planting technology.
