Title: CULTIVATION DEVICE, WALL SURFACE GREENING SYSTEM AND METHOD FOR CIRCULATING NUTRIENT SOLUTION
Abstract:
Provided are a cultivation device wherein fertilization and watering can be easily managed, a wall surface greening system, and a method for circulating a nutrient solution. The cultivation device 1 according to the present invention comprises: a culture solution pooling part 20; a culture medium housing part 40 and a fertilizer housing part 50 which are provided in the space above the culture solution pooling part 20; a liquid feed line 31 which extends from the culture solution pooling part 20 toward the space thereabove and sprinkles a nutrient solution into the space; and a liquid feed pump 30 which feeds the nutrient solution to the liquid feed line 31. The nutrient solution flowing out from the fertilizer housing part 50 is thickened since component(s) are eluted thereinto. Thus, the concentration of the nutrient solution is not lowered even after repeating circulation.
