<P>PROBLEM TO BE SOLVED: To provide a lightweight, small, and inexpensive greening device for growing planted climbing plants without bias and thoroughly greening a rooftop or the like by enabling planting of climbing plants vertically upward a pipe in which liquid manure is stored and circulation of liquid manure in the pipe with an easy structure. <P>SOLUTION: The greening device includes a cultivation pipe whose both end surfaces are closed, in which liquid manure is stored to a prescribed height in the inside, and a plurality of holes for planting climbing plants are formed in a vertical upward peripheral wall, and which extends in the horizontal direction to a prescribed length, a liquid manure transporting pipe which is set inside the cultivation pipe, and extends to the vicinity of both the end surfaces of the cultivation pipe, and a pump which is connected to one end of the liquid manure transporting pipe for forcefully feeding the liquid manure to the other end of the liquid manure transporting pipe. Furthermore, a porous structure is set on a position on a bottom of the cultivation pipe and between the hole on one end among a plurality of the holes formed in the cultivation pipe, and the forcefully feeding pump, and an external pump is connected to the porous structure so that oxygen-containing gas sent from the external pump is supplied from the porous structure into the liquid manure. <P>COPYRIGHT: (C)2010,JPO&INPIT |
