摘　　要：为了研究越冬期日光温室不同升温设施中灌溉水的升温特性,以黄土高原离石区设施蔬菜示范基地日光温室群的越冬期跟踪监测数据为依据,研究了地下浅式升温池和地上深式升温池中灌溉水水温的变化特性。结果表明:(1)升温池内表层水温随气温剧烈波动,而0.3 m以下灌溉水水温不随室温剧烈波动而稳步升温,但升温速率与气温变化有关;(2)地下浅式升温池的升温效果远远领先于其他型式的升温池,地下浅式升温池中灌溉水在升温27 h之后便能达到灌溉要求,而地上深式升温池在升温48 h还没有达到灌溉要求;(3)地下浅式升温池在占地面积、升温效果、管理风险、经济成本等方面明显优于其他结构型式的升温池,推荐地下浅式升温池作为越冬期间日光温室灌溉水的升温设施。研究结果可为北方高寒地区越冬期温室大棚的灌溉水温管理提供具有实际意义的技术支撑,对丰富灌溉理论与技术具有一定的科学价值。In order to study irrigation water heating up characteristics in different heating facilities during winter, the change characteristics of irrigation water temperature are analyzed in underground shallow reservoir and deep reservoir on the ground, based on tracking test data of greenhouse group in Xinyi Town, Lishi District, Shanxi Province during wintering period. The results show that： ① The surface water temperature fluctuates sharply with the air temperature, while the temperature of irrigation water of underground below 0.3 m does not fluctuate steadily with the air temperature, hut the heating rate is related to the air temperature change ; ②The heating effect of underground shallow heating reservoir is far ahead of other types of heating reservoir. The irrigation water temperature in underground shallow heating reservoir can reach the irrigation requirements after 27 hours of warming up, while the deep reservoir on the ground can not reach the irrigation claim; ③ Underground shallow heating reservoir is superior to other types of heating facilities at the area, heating effect, management risk, economic costs and other aspects of structure. The underground shallow heating reservoir is recommended as the irrigation water heating facilities during the winter period. The results can provide practical technical support for the management of irrigation water temperature in the greenhouse during the wintering period of the seasonal frozen soil. It has certain scientific value for the enrichment of irrigation theory and technology.
