Problems solved by technology

[0003] The traditional usage of the substrate modifier is to apply it to the pond during the breeding process. The substrate modifier is splashed into the water body. Most of the live bacteria are applied in the water body, and only a small part acts on the bottom of the pond. Therefore, the dosage is large and the cost is high. and the effect is not significant

specific Embodiment

[0039] 1. Test pool

[0040] Select 2 ponds (area 15.3hm) from Cangzhou Lingang Haiyi Aquaculture Co., Ltd. 2 ) as the test pond, the pond is divided into two pieces, respectively numbered 6# (7.5hm 2 ), 7#(7.8hm 2 ), with a depth of 1.2m, and a pond with the same surrounding conditions as a control, with an area of ​​8hm 2 , numbered 8#.

[0041] 2. Substrate improver

[0042] The substrate improver used in this test is biologically derived from Cangzhou Wangfa Biotechnology Research Institute Co., Ltd., the dosage form is granular, and the main components of the label are biological live bacteria (Bacillus subtilis, composite live bacteria, denitrifying bacteria, etc.), adsorption agent, EDTA and oxygen enhancer, and the content of live bacteria is marked as 200 million to 2.5 billion per gram.

Abstract

The invention provides an aquaculture method pre-burying a viable-bacterium substrate modifier in the bottom of a pond. The method includes the steps of firstly, after the autumn cultivation of the previous year ends, draining pond water, freezing the pond in winter, and drying the pond in the sun in spring to allow the bottom of the pond to crack; secondly, pre-burying the viable-bacterium substrate modifier in April; thirdly, feeding water for the first time 1-5 days after the viable-bacterium substrate modifier is pre-buried; fourthly, feeding water again in multiple steps after the first-time water feeding until the pond is full in late June; fifthly, putting in fry and shrimp seeds in late April. The method has the advantages that the method is simple and lasting in effect, the activebacteria can be planted in the bottom of the pond for a long time to achieve a direct effect, application quantity is evidently lower than that of a traditional method, application cost is lowered greatly, massive-draining and massive-changing management manner of traditional culture is changed at the same time, and the whole culture cycle does not need water changing.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an aquaculture method in which a living bacteria substrate improver is pre-embedded at the bottom of a pool. Background technique [0002] The degradation process of organic matter in the pond bottom is completed with the participation of microorganisms. The use of live bacteria substrate improver is to improve the bottom quality by supplementing the number of live microorganisms in the bottom mud. [0003] The traditional usage of the substrate modifier is to apply it to the pond during the breeding process. The substrate modifier is splashed into the water body. Most of the live bacteria are applied in the water body, and only a small part acts on the bottom of the pond. Therefore, the dosage is large and the cost is high. And the effect is not significant. If the improvement of the live bacteria substrate is pre-buried at the bottom of the pond before the pond...
