Carbon Dioxide Enrichment Technique in Greenhouse Vegetable Culture

Based on the experiment data at home and abroad and the experimental results of CO2 enrichment in the greenhouse vegetable culture in Henan Province, the increasing yield mechanism of CO2, ideal CO2 source, optimum CO2 enrichment concentration and daily enrichment time, calculating method of daily optimum CO2 enrichment quantity and reasonable enrichment model are analysed in order to increase CO2 exploitation and utilization efficiency in agriculture and raise vegetable productivity in greenhouse
