Embodiment 1
[0017] A refined method for cultivating needle-free cuttlefish in a pond; pond construction: the shape of the pond is rectangular, east-west, with an aspect ratio of 2:1, the planting area of aquatic plants is 60%, and it is located in the middle of the pond, with 70-80cm of excavation around the pond The wide ring ditch is used as a temporary pond for river crabs. The pond is generally flat, with a ridge height of 2m, a slope ratio of 1:3, a surface width of 1.5-2m, and a breeding water depth of 1-1.5m. Finally, the bottom of the pool is flat, with a certain slope towards the gate to ensure that the excrement and waste of the culture can be completely discharged. The inside of the gate is constructed with an 8-mesh silk screen to prevent squid from escaping and harmful organisms from entering. Sprinkle 75 kg / mu quicklime water on the bottom of the pond for comprehensive disinfection and kill harmful organisms. After disinfection, the pond and its surroundings are covered wit...
Embodiment 2
[0027] The preparation method is the same as in Example 1.
[0028] In the juvenile stage of growing cuttlefish, fish out, divide and raise in the middle of five ponds, every pond 300, in four ponds, throw in the microbial cuttlefish fertilizer of the embodiment of the present invention 1 and common squid respectively according to the input amount of 200kg per mu Fertilizer (control 1, produced from Beijing Century Arms Biotechnology Co., Ltd. ), the other pond does not put in squid fertilizer (comparison 2), but puts in the same amount of common fish food, the rest of the feeding amount is the same, and the cultivation environment is the same. After 2-4 months of cultivation in Example 1, compare its output and The growth status of cuttlefish is specifically shown in Table 1 and Table 2:
[0029] Table 1 The present invention compares with contrast 1
