The invention discloses a three-dimensional cultivation device for ecological planting. The three-dimensional cultivation device comprises four stand columns used for fixing and supporting; the ecological
system is arranged on the stand column, the ecological
system comprises a
metal cage, a water tank and a cultivation tray, the
metal cage, the water tank and the cultivation tray are sequentially arranged along the stand column from top to bottom, fishes are bred through
livestock manure, vegetables are fertilized through fish
manure, ecological breeding is formed, and a circulating
pipe is communicated with the interior of the water tank in a penetrating mode;
liquid water circulates in the water tank, and
oxygen in the water is increased; the filtering
assembly is arranged on the circulating
pipe and used for separating and filtering fish
feces in the water circulating process, relates to the technical field of ecological planting, and solves the problems that when an existing three-dimensional cultivation device is used, the planting number in unit space is reduced due to the fact that the occupied space is large, and meanwhile only single planting can be conducted; the anti-risk capability is weak during actual production, and large-scale planting is not facilitated.
