[ Objective ] In order to improve the soil temperature of greenhouse at night in winter, develop a built-in device with solar energy to raise the soil temperature. [Method] In no. 8 greenhouse of Delisen Vegetable Garden in Shuixigou Village, the southern suburbs of Urumqi, we carried out the research to increase the soil temperature, and used the method of combing the snakelike solar air collector device and the heat storage of soil. [ Result] When the ambient temperature is - 3 ~ - 10℃ , the device could increase the soil temperature, at 10 ~ 20 cm depth, average 1.5 -3℃. [Conclusion]The built-in solar heating device can improve the soil temperature of the greenhouse effectively at night in winter, and to satisfy the needs of crop.%[目的]提高冬季夜间日光温室的土壤温度,研制内置式太阳能加温装置.[方法]利用蛇形太阳能空气集热器集热结合土壤蓄热的方式,在乌鲁木齐南郊水西沟村德力森蔬菜园8号温室进行了提升地温试验.[结果]当环境温度为-3～- 10℃时,该装置可以使温室土壤10 ～ 20 cm深处的温度平均升高1.5～3℃.[结论]内置式太阳能加温装置能有效提高冬季夜间温室地温,满足作物生长的需要.
