PLANT CULTIVATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/202561
Kind Code:
A1
Abstract:
Provided is a new plant cultivation system that makes it possible to ascertain the actual growth status of plants, and that helps to adjust the harvest time of plants to be produced and to increase profits. On the basis of data acquired by detecting the air environment in a closed space (13) forming a cultivation room (10) for actually cultivating plants (15), a control unit (50) calculates evaluation values of, inter alia, the photosynthesis rate of the plants (15), reflects the evaluation results in the air environment in the cultivation room (10), and controls the growth rate of the plants (15). An air pipeline (21) for circulating air in the cultivation room (10) is connected to the outside of the cultivation room (10), and an air-conditioning unit (23) and a supply pipeline (26) for air supply are connected on the air pipeline (21). The air environment is measured at positions near a pipeline outlet (21a) and a pipeline inlet (21b), and parameters such as changes in carbon dioxide concentration due to the difference in position can be detected. Alternatively, parameters such as changes in carbon dioxide concentration are detected from changes over time.
