Problems solved by technology

However, starting from the ecological characteristics of the pond culture system, fully considering the metabolism-degradation-transformation-utilization-circulation of substances in the process of pond shrimp culture, the method of establishing an ecologically balanced culture system, the negative effects of frequent water changes and sewage discharge and the use of drugs are lacking. The effect is also getting bigger and bigger

Embodiment 1

[0011] In the shrimp pond, first apply the culture fertilizer containing K element; while applying the element fertilizer, apply the bacillus agent (degradation of organic matter, nutrients and beneficial bacteria, etc.) in the same shrimp pond to form a good breeding ecological environment; then Shrimp seedlings are stocked; then trace element fertilizers and bacillus compound preparations (balanced nutrition, water content improvement, dominant flora) are applied, and then enter closed and semi-closed culture.

Embodiment 2

[0013] First apply the cultivation fertilizer containing P element in the shrimp pond; apply the bacillus agent (degradation of organic matter, nutrients and beneficial bacteria, etc.) in the same shrimp pond while applying the element fertilizer to form a good breeding ecological environment; then Shrimp seedlings are stocked; then trace element fertilizers and bacillus compound preparations (balanced nutrition, water content improvement, dominant flora) are applied, and then enter closed and semi-closed culture.

Embodiment 3

[0015] First apply the culture fertilizer containing N element in the shrimp pond; apply the bacillus agent (degradation of organic matter, nutrients and beneficial bacteria, etc.) Shrimp seedlings; then apply trace element fertilizer and bacillus compound preparation (balanced nutrition, improve water content, dominant flora), and then enter closed and semi-closed culture.

Abstract

The method for clean shrimp culture in pond includes the following steps: firstly, applying, culture fertilizer containing elements of K, P and N, and simultaneously applying bacillus preparation into said pond to form good culture ecological environment, then breeding young shrimps, and applying trace element fertilizer and bacillus compound preparation, then making closed and semi-closed culture.

Description

technical field [0001] The invention relates to a method for cleaning and cultivating shrimp in ponds, which belongs to the application technology of fishery science. Background technique [0002] At present, in the application of shrimp farming technology at home and abroad, the process of raising shrimp in ponds is also a process of self-pollution. Various metabolites (including shrimp excrement, residual feed, phytoplankton and Debris) accumulates in the culture pond, causing the gradual deterioration of the culture environment, hindering the growth of cultured prawns, and even causing diseases. The commonly used breeding methods mainly include: ① frequent large-scale water changes and sewage discharge during the breeding process; ② use of water quality and bottom quality improvers; ③ use of disinfection and sterilization drugs. These methods can only temporarily improve the quality of the breeding ecological environment and contribute to the healthy growth of shrimp. H...
