Study on application status of solar thermal technology in solar greenhouse of China

As a facility that uses solar energy, the greenhouse has achieved considerable development in China since the 1980s, and the greenhouse area has increased year by year. In recent years, how to further improve the efficiency of solar thermal utilization in greenhouses has become a research hotspot, and has also developed a variety of solar thermal utilization technologies. This paper will sort out and summarize in this aspect. In the future, under the premise of ensuring the annual supply of vegetables and increasing farmers' income, China's resource-saving and environment-friendly greenhouse production methods will be further upgraded and promoted.
