  • Patent number: 10785926
    Abstract: In a solution cultivation method for a low potassium vegetable, an entire cultivation period from seeding to harvesting is divided into a first cultivation period and a second cultivation period depending on the vegetable to be cultivated. In the first cultivation period, the vegetable is cultivated in a first culture solution containing a first fertilizer for solution cultivation which contains potassium. In the second cultivation period, the vegetable is cultivated in a second culture solution containing a second fertilizer for solution cultivation which does not substantially contain potassium. During the second cultivation period, an air flow is applied at a controlled speed to the growing point of the vegetable.

  • Patent number: 10750673
    Abstract: An illumination apparatus includes first and second light sources arranged substantially linearly; and a light guide member having first and second light receiving portions, and a light emitting portion. The light receiving portions are configured to refract light from the first and second light sources toward the light emitting portion; and the light emitting portion is configured to refract light from the light receiving portions toward a space between the first and second light sources.

  • Publication number: 20190075734
    Abstract: A plant cultivation apparatus includes an illuminator, and a light guide member. The illuminator includes a first light source and a second light source which are arranged in series. The light guide member includes a first light receiver, a light emitter, and a second light receiver, and is disposed to cover at least a portion of a non-light emitting portion between the first light source and the second light source. The first light receiver refracts a first light from the first light source to output the first light toward the light emitter. The second light receiver refracts a second light from the second light source to output the second light toward the light emitter. The light emitter refracts the first light and the second light to irradiate a plant cultivation space with the first light and the second light.

  • Patent number: 9775302
    Abstract: In an air conditioning apparatus, mixed ambient gas obtained by mixing carbon dioxide with ambient gas in a mixing unit communicating with outlets is supplied to a plant substantially uniformly through the outlets installed in the vicinity of the plant, which makes transpiration of leaves of the plant uniform, and further allows air conditioning control to be performed only over the vicinity of the plant and carbon gas concentration to be managed on the vicinity of the plant.

  • Publication number: 20160235018
    Abstract: In an air conditioning apparatus, mixed ambient gas obtained by mixing carbon dioxide with ambient gas in a mixing unit communicating with outlets and, moreover, adjusting temperature and humidity of the mixed ambient gas is supplied to a plant substantially uniformly through the outlets installed in the vicinity of the plant, which makes transpiration of leaves of the plant uniform, and further allows air conditioning control to be performed only over the vicinity of the plant and carbon gas concentration to be managed on the same.
