Problems solved by technology

[0003] At present, the ornamental aquaculture industry usually chooses pig manure, chicken manure, cow manure and other farmyard manure to make organic fertilizer by composting and decomposing method, which is used to cultivate biological live bait for ornamental shrimp seedlings. This kind of conventional poultry and livestock manure has low fertilizer efficiency. The amount of fertilizer used is large, the fertilizer effect when applied to the water body is slow, and the efficiency of fertilizer and water is low, resulting in insufficient supply of b

Embodiment 1

[0018] Watch the crayfish breeding season from September to October. At this time, the ambient temperature is 20-28°C. Collect pigeon manure dry material without mildew and germs from a pigeon farm with convenient sources as the fermentation raw material. The dry material of pigeon manure is 850 grams, 100 grams of wheat bran, 50 grams of BGB microbial agent. Add 667 grams of water to the above-mentioned fermented raw materials and fully stir and mix evenly to obtain a mixed fermented raw material. The weight percentage of water in the mixed fermented raw materials is controlled at 40%, and then the mixed fermented raw materials are poured into a cement fermentation tank to seal; Due to the high temperature in late summer and early autumn, sealed fermentation was carried out for 7 days. During the fermentation process, the pile was turned 3 times to facilitate full fermentation. It is dark brown and has a sour aroma, and it is made into fermented pigeon manure. When watching ...

Embodiment 2

[0021] Watch the crystal shrimp breeding season from April to May. At this time, the ambient temperature is 15-20°C. Collect the dry material of pigeon manure in the pigeon farm as the fermentation raw material. The dry material of pigeon manure is 800 grams, 100 grams of corn flour, and rice bran. 30 grams, BGB microbial agent 70 grams. Add 1000 grams of water to the above-mentioned weighed fermentation raw materials and fully stir and mix evenly to obtain a mixed fermentation raw material. The weight percentage of water in the mixed fermentation raw materials is controlled at 50%, and then the mixed fermentation raw materials are packed into plastic containers. The temperature in early spring is low, and materials such as pigeon manure heat up slowly. Part of the fermented pigeon manure can be backfilled into the container bucket, and the waste heat of fermentation can be used to promote the rapid heating and fermentation of the material, which can shorten the fermentation ti...

Embodiment 3

[0024] Watch the crystal shrimp breeding season from April to May. At this time, the ambient temperature is 15-20°C. Buy dried pigeon manure that is dried and stored in bags at the pigeon farm as fermentation raw materials, 750 grams of pigeon manure, 100 grams of rice bran, 50 grams of wheat bran, 100 grams of BGB microbial agent. Add 1,500 grams of water to the above-mentioned weighed fermentation raw materials and fully stir and mix them evenly to obtain a mixed fermentation raw material. The weight percentage of water in the mixed fermentation raw materials is controlled at 60%, and then the mixed fermentation raw materials are poured into a fermenter with a plastic film. In the earthen pond, the temperature in early spring is slightly lower, and the sealed fermentation is for 12 days. During the fermentation process, the number of turnings is increased, and the turnings are turned 5 times to ensure full fermentation. When the surface of the mixed fermentation raw materials...

Abstract

The invention relates to a quick water fertilization method for adding fermented pigeon dung to cultivate food organisms for ornamental shrimps, which includes the steps: well mixing dry pigeon dung, auxiliary material and BGB (brilliant green bile broth) microbial inoculants with added water to obtain mixed fermented stock, wherein the auxiliary material is one or mixed two of wheat bran, corn starch and rice husk; hermetically placing the mixed fermented stock in the shade at the ambient temperature of 15-28 DEG C for viable microbial fermentation, and obtaining fermented pigeon manure when the surface of the mixed fermented stock is covered with white filiform mycelia; cleaning and disinfecting a breeding pond for ornamental shrimps, applying 75-150g of the fermented pigeon manure into the pond per square meter of water in the breeding pond for ornamental shrimps, and placing young ornamental shrimps into the pond for cultivation 3-5 days after application of the fermented pigeon manure. The water fertilization method has the advantages of short fermentation time, fast water fertilization speed, low fertilizer consumption, high food organism cultivating efficiency and the like.

Description

technical field [0001] The invention relates to a fertilizer and water method for ornamental shrimp bait organisms, in particular to a rapid fertilizer and water method for cultivating ornamental shrimp bait organisms by adding fermented pigeon manure, which belongs to the technical field of aquaculture. Background technique [0002] The biological cultivation of bait is the key to improving the survival rate of shrimp seedlings in the breeding process of ornamental shrimp. To realize the large-scale artificial propagation of ornamental shrimp, it is necessary to provide a large amount of palatable opening bait for the shrimp seedlings that have just emerged from the film, and suitable biological live bait can undoubtedly be used. Greatly improve the survival rate of seedlings. [0003] At present, the ornamental aquaculture industry usually chooses pig manure, chicken manure, cow manure and other farmyard manure to make organic fertilizer by composting and decomposing metho...
