Résumé

Growth prediction method depending on a cultivation condition is important for planning and operating vegetable production in a plant factory. In this paper, it was proposed to incorporate the growth prediction method based on plant physiology into the air conditioning simulation tool. Photosynthetic rate equation was expanded by incorporating light intensity, air temperature, carbon dioxide concentration and wind speed dependency. Plant characteristic values necessary for photosynthetic rate were identified by cultivation experiments. Growth amount of leaf area was modeled as a growth curve and coupled with photosynthetic rate. Comparing the prediction results with cultivation experiment results, it was confirmed that this prediction method has accuracy for practical use.
