Bottom-sowing bacterium device for improving pond water quality and application thereof

Technical Field

The invention belongs to the technical field of aquaculture equipment, and particularly relates to a bottom bacterium sowing device for improving pond water quality and application thereof.

Background

Along with the development of economy, the living standard of people is increasingly improved, and the public preference degree on aquatic products is also increasingly high. In order to meet the demand of people on aquatic products, the scale of freshwater aquaculture is increasingly enlarged. Wherein, the pond culture is an important component of fresh water culture in China, and the yield of the pond culture accounts for more than 70 percent of the total culture yield.

At present, due to high stocking density and large feeding amount, the aquaculture environment is seriously polluted by excrement of fish and shrimp, residual bait and the like, and the growth of the fish and shrimp is influenced. In the prior art, harmful ingredients such as nitrite, ammonia nitrogen and the like in a pond are degraded by putting a microbial preparation into the pond, strains are mainly splashed to the water surface in a putting mode, cannot act on the bottom of the pond in the first time, the oxygen content of the bottom of the pond is low, and the effects of the strains cannot be fully exerted after the strains sink to the bottom, so that the using effect of the microbial preparation in the pond is reduced.

A method for improving the water quality of a pond is characterized in that the self-settling pipe is laid in a water body, and a water quality improving microbial inoculum flows out of holes of the self-settling pipe and is sown in the water body.

Preferably, when the aerobic bacteria are required to be sowed in the pond, the bottom-sowing bacteria device is firstly opened to introduce air into the pond, the dissolved oxygen in the water body is increased, and then the aerobic bacteria agent is sowed in the pond by the bottom-sowing bacteria device.

Preferably, when the anaerobic bacteria are required to be sowed in the pond, the air is stopped to be introduced into the pond, the dissolved oxygen of the water body is reduced, and then the anaerobic bacteria agent is sowed in the pond by the bottom-sowing bacteria device.

Preferably, the aerobic bacterial agent is: nitrobacteria, nitrite bacteria, actinomycetes and bacillus subtilis.

Preferably, the anaerobic microbial inoculum is: rhodopseudomonas palustris, Lactobacillus acidophilus and Bacillus coagulans.

Preferably, the number ratio of the nitrobacteria, the nitrite bacteria, the actinomycetes and the bacillus subtilis is 2 (1-2): 1:1.

Preferably, the number ratio of the rhodopseudomonas palustris, the lactobacillus acidophilus and the bacillus coagulans is 2:3 (1-2).

Has the advantages that:

the invention discloses a bottom-sowing device which is convenient to lay, can be used for sowing strains on the bottom of a pond, is simple to operate, can be used as bottom oxygenation equipment at ordinary times, can also be used for carrying Internet of things equipment, and is time-saving and labor-saving. The invention can improve the utilization rate of the water quality improving strain, reduce the cultivation cost and improve the cultivation success rate, thereby increasing the cultivation income.

Detailed Description

When the bottom-sowing device is used, when aerobic bacteria are required to be sown in the pond, the bottom-sowing device is firstly opened to introduce air into the pond, the dissolved oxygen in water is increased, and then the bottom-sowing device is used for sowing the aerobic bacteria in the pond. When the anaerobic bacteria are required to be sowed in the pond, the air is stopped to be introduced into the pond, the dissolved oxygen of the water body is reduced, and then the anaerobic bacteria are sowed in the pond by the bottom-sowing bacteria device.

Example 1: a preparation method of anaerobic bacteria agent.

(1) Fermenting strains: fermenting rhodopseudomonas palustris, lactobacillus acidophilus and bacillus coagulans respectively, and then mixing fermentation liquids of the rhodopseudomonas palustris, the lactobacillus acidophilus and the bacillus coagulans respectively, wherein the proportion of the rhodopseudomonas palustris, the lactobacillus acidophilus and the bacillus coagulans is 2:3 (1-2), so as to obtain a mixed strain;

(2) freeze-drying the mixed strain obtained in the step (1) to obtain an anaerobic microbial inoculum;

(3) mixing the anaerobic bacteria agent with water in a proportion of 5g (1-2) L to obtain the pond water quality improving bacteria liquid.

Example 2: a method for preparing aerobic bacteria agent.

(1) Fermenting strains: respectively fermenting and culturing nitrobacteria, nitrosobacteria, actinomycetes and bacillus subtilis under the condition of 30 ℃ for 24-36 h;

(2) the method comprises the following steps of (1) mixing nitrobacteria, nitrite bacteria, actinomycetes and bacillus subtilis according to the number ratio of 2: 1:1, and freeze-drying to obtain an aerobic microbial inoculum;

(3) mixing aerobic bacteria with water according to the proportion of 10 g: (1-2) L to obtain pond water quality improving bacterial liquid.

Example 3:

experiments are carried out by using a fish and shrimp farm located in a tin-free city tin mountain area, the aerobic bacteria prepared in the embodiment 2 are upwards sown from the bottom of a pond through a bottom sowing device in an experimental group, and a full-pond sowing mode is adopted in a control group. Before seeding, the experimental group firstly introduces air into the pond so as to improve the oxygen content of the water body.

Control group: the area is 0.5 mu, and the water depth is 2 m; sprinkling 500 ml of pond water quality improving microbial inoculum to the whole pond;
