Some Western developed countries, especially Europe and the United States, have begun to develop greenhouse planting technology relatively quickly. Developed countries such as the United States, Israel, and Canada have begun to use instruments to collect on-site information in greenhouses and control them based on indicators, basically realizing the mechanization and automation of agricultural production. However, at that time, only single-factor control technology was used in greenhouse control, that is, only environmental conditions such as temperature and humidity, light intensity, and CO2 were controlled separately.
