The tomato pathogenic fungus detecting apparatus according to the present disclosure is characterized by including an artificial cell wall, a test sample solution inlet provided above the artificial cell wall, and a culture solution storage part provided under the artificial cell wall, wherein a culture solution contains a 15 mM to 30 mM buffer solution of a citrate salt in the culture solution storage part, and the culture solution has a pH of 5 to 5.5.

Abstract: The hydroponic cultivation apparatus comprises: a cultivation tank that has a light shielding property and is configured to accommodate underground part of a plant; a partitioning portion that has a light shielding property and that is configured to cover the opening at the upper end of the cultivation tank and partitions an underground space where the underground part of the plant grows and an aboveground space where aboveground part of the plant grows, wherein the partitioning portion includes; a fixed member, a position of which is fixed with respect to the cultivation tank, and including a through hole surrounding a stem of the plant and maintains a closed state where it is suppressed that light is irradiated to the underground part of the plant; and a door member that is attached to the fixed member in a state where it is movable with respect to the fixed member and changes to a closed state where it is suppressed that light is irradiated to the underground part of the plant and to an open state where it

Abstract: A plant raising apparatus: a light source that emits light traveling toward an aboveground part of a plant; a heat insulating portion that has a light transmitting property and that partitions a space at a side of the light source and a space at a side of the aboveground part; and an air blowing mechanism that generates an airflow at a space between the light source and the heat insulating portion. Thereby, it is suppressed that the heat of high temperature air staying above the heat insulating portion having a light transmitting property adversely affects the plant.

Abstract: A hydroponic cultivation apparatus is provided with a partitioning member including a swelling member in which a first through hole is formed and having a first main surface and a second main surface which are directed to opposite sides to each other. The hydroponic cultivation apparatus also has a mounting surface provided at a position opposing to the first main surface in a first space enclosed by a plurality of surfaces including the first main surface. An underground part is arranged in the first space, and a stem part is inserted into the first through hole.

Abstract: A hydroponic cultivation apparatus, wherein a plant that stores nourishment in an underground portion thereof is raised by hydroponics, including: a nutrient solution flow path provided at a bottom portion of a cultivating container; a partitioning member arranged above the nutrient solution flow path, including a through-hole having a size that a root and a stolon produced from the underground portion of the plant pass therethrough, and supporting the stolon and a tuber extended from underground portion with an upper surface thereof. The hydroponic cultivation apparatus makes the root produced from the underground portion pass through the through-hole from an upper surface side toward a lower surface side of the partitioning member, and immerses the root in the nutrient solution flow path and grows the stolon on the upper surface of the partitioning member and produces the tuber of the plant on the upper surface of the partitioning member.
