Abstract: Aiming at the problem of low temperature at night in the northern solar greenhouse, the paper aimed to collect and utilize surplus solar energy in the greenhouse during the day, on the basis of theoretical analysis of the characteristics of phase change materials, the two-stage phase change heat storage and release system based on the tube packaging method was developed, and the winter application effect test was carried out in the solar greenhouse in Beijing through comparative experiments. The results showed that the designed system had good warming effect on indoor air temperature and soil temperature in winter. In terms of indoor air temperature, during the test cycle, the average indoort emperature during night（from 17:00 to 08:00 in the next day） of the experimental greenhouse was 1.0 ℃ higher than that of the comparative greenhouse, and the average minimum temperature of the experimental greenhouse was increased by 1.2 ℃. Under sunny and cloudy weather conditions, the average indoor temperature during night of the experimental greenhouse was increasedby1.3 ℃, 1.2 ℃, respectively, the minimum temperature of the experimental greenhouse was 1.5 ℃, 1.7 ℃ higher than that of the comparative greenhouse. Under the condition of snowy weather without heat preservation quilt for two days and one night, the indoor temperature of the test greenhouse was higher than that of the control greenhouse, the maximum temperature difference was 1.9 ℃. In addition, the average soil temperature at 10 cm and 15 cm of the experimental greenhouse was increased by 0.6-0.8 ℃ on sunny and cloudy days. The findings show that the system has aprosperous heat storage and release capacity, which can improve the thermal environment of solar greenhouse.
