Summary: | Abstract
CO
2
enrichment is an essential environmental control technology due to its significantly enhancing effect on crop production capacity. Despite being a key energy consumer in protected agriculture (i.e. greenhouse systems), CO
2
enrichment remains at a low energy use efficiency level, highlighting the need for developing more energy-efficiency strategies for CO
2
enrichment. Therefore, this study employed the computational fluid dynamics (CFD) simulation method to replicate the CO
2
diffusion process resulting from CO
2
enrichment in three commercial strawberry greenhouses with varying geometric characteristics. Based on the CFD-simulated CO
2
concentration distributions, the leaf photosynthetic rate was calculated using a mathematical model group. The CO
2
enrichment efficiency was then analysed by calculating the ratio of increased photosynthesis across the cultivation area to the amount of energy (in CO
2
equivalent) used. The efficiency peaked when the average CO
2
concentration was approximately 500 μmol mol
−1
, thereby providing guidance for determining the target concentration of CO
2
enrichment in production. Although this study is limited as the CFD simulation only considered a typical short-period CO
2
enrichment event, future research will provide a broader analysis by considering changes throughout the day. |
