Embodiment 1

[0029] Bacteria powder 1, bacteria powder 2 and bacteria powder 3 are mixed according to 1:2:1 (weight ratio), and vacuum-packed to become a compound bacterial agent for improving the bottom mud environment of aquaculture ponds.

Embodiment 2

[0031] Bacteria powder 1, bacteria powder 2 and bacteria powder 3 are mixed according to 2:1:2 (weight ratio), and vacuum-packed to become a compound bacterial agent for improving the bottom mud environment of aquaculture ponds.

Embodiment 3

[0033] Bacteria powder 1, bacteria powder 2 and bacteria powder 3 are mixed according to 1:1:1 (weight ratio), and vacuum-packed to become a compound bacterial agent for improving the bottom mud environment of aquaculture ponds.

[0034] The compound microbial agent prepared by embodiment 1-3 is carried out the improvement of the composite environment of cultured fish pond bottom mud:

[0035] Apply once every 10 days, use 1200 grams of compound bacterial agent per mu per meter of water depth, and evenly sprinkle it directly into the culture pond.

[0036] The ammonium nitrogen was 0.9mg / L and the nitrite was 0.4mg / L before the treatment with the compound bacterial agent, and the ammonia nitrogen was 0.05mg / L and the nitrite was 0.02mg / L after the application of the compound bacterial agent. The degradation of ammonia nitrogen and nitrite The rate reached over 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 invention relates to the technical field of improving bottom mud of cultured fish ponds, in particular to a compound bacterial agent for improving the bottom mud environment of culture ponds, a preparation method and application thereof. Background technique [0002] At present, high-density pond aquaculture is the main method in China. Although this intensive aquaculture meets people's demand for aquatic products to a large extent, the aquaculture environment and aquaculture safety have become the most concerned issues of consumers. The utilization rate of nutrients in this high-density and intensive farming method is low. Only a small part of the feed is absorbed and utilized by the farmed animals to form biomass, and most of it is absorbed by the animals through physical, chemical or biological actions Gradually settles into the silt at the bottom of the pond. This relatively closed semi-static breeding environment has relatively weak self-puri...
