一般注記Because spatial volume and energy consumption are limited in plant cultivation in space, it is necessary to increase plant density while simultaneously increasing lighting efficiency. Light-emitting diodes (LEDs), which have excellent luminous efficiency, durability, and safety, and are capable of accurate wavelength control over a wide range, are used as light sources. The environment, such as temperature and humidity, is controlled to the general optimum value on earth, and CO2 concentration is controlled to 0.7 to 1 mmol mol(exp -1).
To establish environmental control technology for efficient plant production using space plant cultivation equipment, physical environmental factors for gas exchange and plant growth (light intensity, light-dark period, light wavelength, temperature, humidity, CO2 concentration, airflow, medium moisture, and medium aeration), as well as the effects of space-specific environmental conditions, such as microgravity and a low-pressure environment, must be considered.
An environmental control that maximizes the photosynthetic rate is important in plant production. Here, we first examined the control of environmental factors common to plant production on earth, the effects of major physical environmental factors on photosynthesis, and environmental control issues under the microgravity of the universe.
