Abstract: The paper aims to provide targeted agricultural meteorological services to guiding the facility agriculture production. We studied the effect of different concentrations of carbon dioxide on greenhouse tomato growth and development, with‘Meihong 2’tomato as the experimental material, by comparison with the tomato under natural environment CO2 concentration in greenhouse. After two years of experiment, the results showed that the increase of CO2 could promote the growth and development of tomato, and the plant height, stem diameter, leaf number, fruit number and yield were increased. The effect of increasing CO2 concentration by 1200 mg/kg was better than that by 700 mg/kg. It is suggested that CO2 enrichment in solar greenhouse can promote the photosynthesis of tomato, and is beneficial to its growth and yield.
