However, algae can be bred in the aquatic weed breeding process, in order to avoid the large outbreak of algae caused by the excessive breeding of aquatic weeds, the coverage rate of the aquatic weeds in the pearl mussel breeding pool 1 is controlled to be 60-65%, the breeding range of the aquatic weeds is controlled, the outbreak of algae is easily prevented, and a user can control the breeding scale of the aquatic weeds by additionally installing or reducing the number of the aquatic weed breeding boxes 4 on the mounting frame 3 and the size of the breeding space in the aquatic weed breeding boxes 4, so that the algae outbreak caused by the large breeding of the aquatic weeds is prevented.
When needing to install additional or reduce pasture and water artificial containers 4's quantity, the user inserts two hoists respectively with a pair of connection rope 7 in, then uses the hoist rolling to connect rope 7, make mounting bracket 3 by the pulling rise to the surface of water on, then the user loosens the locking screw 5 of 4 lower extremes of pasture and water artificial containers, can make pasture and water artificial containers 4 and the separation of mounting bracket 3, the user still can prune and clear up and disinfect the pasture and water of excessive reproduction in other pasture and water artificial containers 4 when mounting bracket 3 is pulled rise to the surface of water on.
When the culture space in the aquatic plant incubator 4 needs to be adjusted, a user can pull out the partition plate 405 in the box body 402, then clean aquatic plants in the box body 402, and then insert the partition plate 405 into the clamping grooves 404 at other suitable positions, so that the adjustment of the size of the culture space in the aquatic plant incubator 4 can be completed, and a technician can select a suitable water surface vehicle, such as a boat and the like, when treating the aquatic plant incubator 4.
The scheme is that a large amount of aquatic weeds are hung and cultured below the pearl mussel hanging and culturing cage, oxygen generated by photosynthesis of the aquatic weeds is provided for the pearl mussels and the pearl mussel culturing pool 1, oxygen enrichment of the pearl mussel culturing pool 1 is realized, as the fertility of the culturing water is high, the propagation of algae is fast, in order to prevent a large amount of explosion of algae cultured during aquatic weeds culturing, the aquatic weeds culturing box 4 is hung and cultured nearby the pearl mussel culturing cage, the pearl mussels in the pearl mussel culturing cage are enabled to prey on the algae to control the growth, meanwhile, the effect of feeding the pearl mussels can be achieved, in order to prevent the excessive propagation of the algae caused by the fact that the propagation speed of the algae is greater than the prey speed of the pearl mussels, the growth of the aquatic weeds is limited by regulating the number of the aquatic weeds culturing boxes 4 and the size of culturing spaces in the aquatic weeds culturing boxes 4, the coverage rate of the aquatic weeds in the culturing pool is kept between 60% and 65%, the growth of the algae is limited by limiting the growth of the, therefore, the aim of limiting the growth of algae is achieved, the cultured aquatic weeds are rich in oxygen for culturing the pearl mussels, and algae outbreak and excessive growth of the aquatic weeds caused by the culture of the aquatic weeds are prevented.
The above; but are merely preferred embodiments of the invention; the scope of the invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; according to the technical scheme and the improvement concept of the invention, equivalent substitutions or changes are made; are intended to be covered by the scope of the present invention.
