Embodiment 1

[0029] The bacterial powder 1, the bacterial powder 2, and the bacterial powder 3 are mixed in a ratio of 1:2:1 (weight ratio), and then vacuum-packed to become a compound microbial agent for improving the environment of the bottom mud of the breeding pond.

Embodiment 2

[0031] The bacterial powder 1, the bacterial powder 2, and the bacterial powder 3 are mixed according to 2:1:2 (weight ratio), and then vacuum-packed to become a compound microbial agent for improving the bottom mud environment of the breeding pond.

Embodiment 3

[0033] The bacterial powder 1, the bacterial powder 2, and the bacterial powder 3 are mixed in a ratio of 1:1:1 (weight ratio), and then vacuum packaged to become a compound microbial agent for improving the bottom mud environment of the breeding pond.

[0034] The compound bacterial agents prepared in Examples 1-3 were used to improve the compound environment of the bottom mud of aquaculture fish ponds:

[0035] It is applied once every 10 days, and 1200 grams of compound bacteria are used per acre at a water depth of one meter, and they are directly and evenly sprayed into the breeding pond.

[0036] The ammonia nitrogen was 0.9mg / L and the nitrite was 0.4mg / L before the compound bacteria treatment, the ammonia nitrogen was 0.05mg / L and the nitrite was 0.02mg / L after the compound bacteria treatment was used, the degradation of ammonia nitrogen and nitrite The rate reaches more than 94%.

Abstract

The invention discloses a complex microbial inoculant for improving the aquaculture pond bottom mud environment and a preparation method and application thereof. The complex microbial inoculant is composed of bacterial powder 1, bacterial powder 2 and bacterial powder 3. The bacterial powder 1 is Thermochromatium tepidum ATCC 43061. The bacterial powder 2 is Thioalkalivibrio denitrificans DSM 13742. The bacterial powder 3 is Achromobacter denitrificans DSM 30026 and Achromobacter xylosoxidans subsp.denitrificans ATCC15173. The weight ratio of the bacterial powder 1 to the bacterial powder 2 to the bacterial powder 3 is 1-2 to 1-2 to 1-2. The complex microbial inoculant can deeply permeate into the bottom of a pond, quickly and efficiently degrade residual feeds, excrement, flora and fauna dead bodies and organic detritus depositing to the bottom of the pond, remarkably reduce ammonia nitrogen, nitrite, sulfide and other hazardous substances at the bottom of the pond, and then achieves the purposes of improving the pond bottom mud environment and purifying the water.

Description

Technical field [0001] The present invention relates to the technical field of improving the bottom mud of aquaculture ponds, in particular to a composite microbial agent for improving the bottom mud environment of aquaculture ponds, and a preparation method and application thereof. Background technique [0002] At present, high-density pond farming is the main method in China. Although this intensive aquaculture meets people's demand for aquatic products to a large extent, the breeding environment and breeding safety have become the most concerned issues of consumers. The utilization rate of nutrients in this high-density and intensive breeding method is low. Only a small part of the feed is absorbed and used by the farmed animals to form biomass, and most of the feed is physically, chemically or biologically combined with their excrement and corpse remains. Gradually settle into the silt at the bottom of the pond. This relatively closed semi-static breeding environment has rel...
