Application and Prospect of CO₂ Enrichment Technology in Agriculture

With the increasing consumption of fossil fuels for human activities, the emissions of greenhouse gases, such as CO₂, have significantly increased, resulting in an intensified greenhouse effect. As an important element for plant photosynthesis, CO₂ enrichment in an appropriate environment can promote photosynthetic rate, organic matter accumulation and the growth rate of plants. The CO₂ enrichment technology should be widely used in agriculture. However, only a few studies have emphasized the role of CO₂ enrichment technology and its development in agriculture. In study, four CO₂ enrichment technologies were introduced based on the different generation principles of CO₂. It can be concluded that the existing CO₂ enrichment methods and technologies were benefited from the development of agricultural information technology. Further, the framework of agricultural information technology in CO₂ enrichment is proposed. It will provide an innovative idea for mitigating global climate change and help future research on the environmental adaptability of farmland crops.
