Description

  The present invention relates to a watering system.

  In recent years, Patent Document 1 proposes an apparatus for preparing a plurality of planters containing appropriate soil on a site or a roof and cultivating plants with the planters as one countermeasure for reducing the heat island phenomenon which has been a problem. ing. This is equipped with a water reservoir for placing flower pots, and the larger the site or the rooftop area, the greater the number of plants that must be prepared. An automatic irrigation device is provided to which a water supply pipe is connected in order to solve the problem of increasing the cost if a specialist is requested for water management.

  Moreover, the multipurpose hydroponic cultivation planter for indoors which connects many planters with the desired arrangement pattern is proposed by the following patent document 2. FIG. This is formed by watertightly connecting a plurality of boxes each having an upper surface as an opening for planting and provided with a communication hole on a side surface thereof.

  Moreover, as shown in the following patent document 3, a box-shaped planter that puts water therein is provided, and the planter is connected through a hose connected to an overflow hole provided in each planter.

  On the other hand, a nutrient solution supply apparatus using a water supply pattern different from these hydroponics is proposed in Patent Document 4 below. This is because a net-like sheet is provided in a long box whose upper surface is an opening for planting, the inside of the net-like sheet is used as a culture medium, a supply pipe for spraying a nutrient solution from below the mesh sheet, and a nutrient solution as a culture medium There are provided two systems of liquid supply pipes for irrigation toward the upper surface, and the nutrient solution supply of both is switchable as necessary.
