WIPO Patent Application WO/2006/070784

Kind Code:

A1

Abstract:

A plant culturing device capable of distributing a culturing liquid to the roughly entire part of a culture medium in a short operation time without separately installing a supply passage and a supply pump communicating with a tank. A pump (P) switchable between a state in which the stored liquid (5) is fed to a culturing container and a state in which an excess liquid (6) and an aerating air (7) are allowed to flow into the tank is installed in a communication passage (4) allowing the culturing container (1) for plant (A) to communicate with the tank (3) for the culturing liquid (2). The device also comprises a switching part (16) allowing the communication passage to communicate with the culturing container on the bottom side, allowing a supply passage (12) capable of supplying the stored liquid from the opening part side for planting to the culturing container to be branched and connected to the communication passage, and selectively switchable between a state in which the supply passage is allowed to communicate with the tank and a state in which the communication passage is allowed to communicate with the tank. The pump is installed on the upstream side of the branched connection part of the supply passage in the culturing liquid supply direction.
