The invention relates to a multifunctional ground wire storage trolley. The multifunctional ground wire storage trolley comprises a trolley frame; a lifting base is arranged on the trolley frame; a box body is arranged on the lifting base; a hand wheel driving mechanism is arranged on one outer side wall of the box body; a rotating table which is in power connection with the hand wheel driving mechanism is rotationally arranged at the bottom of the box body; a plurality of rotating frames which are vertically arranged are arranged on the periphery of the top surface of the rotating table at intervals; the top ends of the rotating frames are connected to a disc, and the disc is rotationally connected to the top wall of the box body; the rotating frames each comprise a base plate, a top plate and a plurality of supporting rods, wherein the supporting rods are connected between the base plate and the top plate and are annularly arranged at intervals; the base plates are rotationally arranged on the rotating table; the top plates are rotationally connected to the bottom of the disc; annular hanging frames are fixedly arranged at the tops of the rotating frames; a plurality of upper hanging rods which correspond to the supporting rods in a one-to-one mode are annularly arranged on the annular hanging frames; and the bottom of each supporting rod is provided with a lower pull rod in a sliding mode. The multifunctional ground wire storage trolley has the advantages that the structure is simple, the control is flexible and convenient, the labor intensity of workers can be greatly reduced, and the working efficiency can be improved.

The invention discloses a zero-emission California perch temperature-controlled seedling raising method, which belongs to the technical field of aquaculture and includes site selection and treatment, installation of filtering devices and heating pipes, plant cultivation in artificial wetlands, cleaning and arrangement of seedling ponds, water temperature control, and fish fry In the steps of stocking, breeding management, and large-scale fingerling cultivation, using industrial circulating water facilities, through the joint application of water temperature control technology and water quality treatment technology, the factory temperature-controlled seedlings of California perch are carried out in late winter and early spring to grow large-scale fish. After the fish species are raised, they will be reared in separate ponds outdoors, and they will reach market specifications by the end of September. The present invention can cultivate large-scale California perch seedlings, realize the goal of cultivating and going on the market in the same year, and avoid feeding chilled fish in the whole breeding process, which can save costs.
