The invention discloses a pond ecological breeding
system for river crabs in southern areas. The pond ecological breeding
system comprises a pond body, sandbag modules, a cage body, a
drainage ditch and a plurality of planting frames; the sandbag modules are laid at the bottom of the pond body and are arranged in rows and columns, interval lanes are formed between the adjacent rows and columns, and fine sand is laid in the interval lanes; the cage body is laid along the interval lanes, a mud pumping pipeline is laid along the interior of the cage body, a mud suction opening is formed in the mud pumping pipeline, and an anti-escape net is arranged outside the cage body in a covering manner; the
drainage ditch is arranged along one side of the pond body, and a
water level adjusting
pipe is arranged in the
drainage ditch; and the planting frames are arranged in the pond body, a plurality of rows of planting grooves are formed above the planting frames, and planting boxes used for planting aquatic plants are arranged in the planting grooves in a matched manner. According to the pond ecological breeding
system, the sandbag modules can be directly laid at the bottom of a pond to cover
sludge, construction is easy, convenient and rapid, most of the
sludge can be covered, it is avoided that bottom
sludge suspends to affect
water quality, and the problems that in the traditional technology, the work amount of hardening the bottom of the pond with
cement is large, the construction period is long, and the cost is high are solved.
