摘要: To improve the phenomenon of uneven light environment and low indoor temperature at night caused by crop and structure occlusion in Chinese solar greenhouse, this study proposes a columnar energy storage device filled with composite phase change materials and combined with a reflecting film based on the full spectrum utilization of solar energy, which is placed on the north wall surface of Chinese solar greenhouse to comprehensively regulate the photothermal environment and a control greenhouse without heating is also set up for comparison. After testing, at 50 degrees C and an optical path length of 50 mm, the composite phase change materials with a concentration of 0.001 % nanoparticles have an average transmittance of 66.7 % in the photosynthetically active radiation band, and an average sum of absorption and reflectance of 79.8 % in the near infrared spectrum band. The greenhouse experiment results showed that the average growth factor index G of plants in the experimental greenhouse increased by 17.53 %. The average air temperature in the greenhouse increased by 1.70 degrees C at night. During the experiment, the average heat collection efficiency of columnar energy storage devices was 40 %. This study provides a new approach for efficient greenhouse production using full spectrum solar energy utilization.
