<p>PROBLEM TO BE SOLVED: To provide an automatic watering system in a three-dimensional garden laid on a multilayered building, an automatic nutrition and medicament replenishing system, and an automatic mud recovery system.SOLUTION: In an automatic watering system in a three-dimensional garden, a drainage port 23 and a water supply port 21 connected by vertical pipes 3, each floor garden 6, an irrigation space 20, a surface soil dry sensor 7, and controllers 101, 102, 106, 107, 108 are disposed on each floor, a water supply tank 29 is disposed on an uppermost part of the building, and a storage tank 27 is disposed on a bottom layer of the building. Drainage water through the vertical pipe 3 from the drainage port 23 on each floor is supplied to the storage tank 27. Water is pumped up from the storage tank 27 to the water supply tank 29, and is supplied through the water supply port 21 on each floor from the water supply tank 29 to each floor garden 6. The controller controls, based on data from the surface soil dry sensor 7, amounts of water supply or drainage by controlling the water supply port 21 and the drainage port 23, and automatically replenishes rain water, reuse of the drainage water or clean water for the evaporated water to circulate water for irrigation.</p> |
