摘　　要：为探讨冬季南疆地区日光温室夜间低温问题,以新疆和田市和田县日光温室为研究对象,在日光温室后墙上设计了网状集散热水管,并在阴天蓄热水池蓄热量低的情况下通过电加热方式继续升温,并分析了该系统对温室温湿度变化及番茄生长状况的影响。试验结果表明:网状集散热水循环系统在晴天可以提高室温1.7~2.1℃,通过电加热结合的方式在阴天提高室温1.6~2.0℃;系统平均蓄热量为226.8~302.4MJ,夜间放热量为151.2~201.6MJ。每10天测定一次试验温室和对照温室番茄的株高与径粗,结果表明:生长期的试验温室株高较对照温室高出5.1%,系统能有效改善温室夜间温湿度环境,促进温室番茄生长。In order to discuss the problem of low temperature at night in the solar greenhouse in the south of Xinjiang in winter,taking the solar greenhouse used in Hetian County of Xinjiang as the research object,a net collecting and cooling water pipe was designed on the back wall of the solar greenhouse,and the temperature of the solar greenhouse continued to rise through the electric heating method when the heat storage pool was low in cloudy days,and the influence of the system on the temperature and humidity change and tomato growth condition in the greenhouse was analyzed.The test results show that the temperature of room temperature can be increased by 1.7-2.1℃ in sunny days and 1.6-2.0℃ in cloudy days by electric heating.The average heat storage capacity of the system is 226.8mj-302.4mj,and the heat release at night is 151.2mj-201.6mj.The plant height and diameter of Tomato in the experimental greenhouse and the control greenhouse were measured every 10 days.The results showed that the plant height of the experimental greenhouse was 5.1% higher than that of the control greenhouse.The system can effectively improve the temperature and humidity environment of greenhouse at night and promote the growth of Tomato in greenhouse.
