Description

The present invention relates to a plant cultivation device and a cultivation system.

In recent years, wall greening can be expected to have many effects in addition to mitigating the heat island phenomenon, which has become a problem in urban areas, and energy conservation measures. However, wall surface greening requires a three-dimensional greening, which tends to increase the installation cost. In addition, since wall greening requires a great deal of labor and cost to maintain its aesthetic appearance even after completion, it has not become widespread.

Most of the methods for greening the walls are to grow plants using the soil surface. However, planting is used as a cultivation container for wall greening in places where there is a constraint such as not being able to secure the soil surface. For the irrigation in planting wall surface greening, the running-and-run method of sprinkling tap water on the medium is often adopted.

Further, as a watering method other than pouring, there is a method called bottom surface water supply (see Patent Document 1). The planter described in Patent Document 1 is installed outdoors, and is provided with a housing having an open upper end and a bottom at the bottom of the housing, and stores the amount of water that does not become empty at the time of the most evaporation. A water tank, a medium provided in the upper part of the housing for dropping excessive rainwater to the water tank, and a water supply member for supplying the water in the water tank to the medium when the medium is dried It is a watering type planter.
