Embodiment 1

[0023] There is a pond with a size of 110 square meters for prawns. Before stocking prawns, perform the following steps:

[0024] (1) Measure the average pH of pond water at multiple points to 5.6, which is slightly acidic;

[0025] (2) The pH control layer in the disinfection device is set to coral sand, and the pH value of the water passing through the disinfection device is controlled in the range of 6.5-7.0;

[0026] (3) Install the disinfection device and connect the disinfection device to the water pump, turn on the water pump, make the pond water flow through the disinfection device for disinfection, the cross-sectional area of ​​the water pipe is 0.03m 2 , The water flow velocity is 1m / s;

[0027] (4) Move the position of the water pump head in the pond every 30-40 minutes;

[0028] (5) Check the disinfection of pond water every 3 hours. During the test, take samples from the nearest to far away from the pump, and take 10 samples to measure pH, ammonia nitrogen content, and nitr...

Embodiment 2

[0040] There is a pond with a size of 90 square meters for prawns. Before stocking prawns, the following steps should be carried out:

[0041] (1) Measure the average pH of pond water at multiple points to 7.5, which is slightly alkaline;

[0042] (2) Use the disinfection device as described in embodiment 1, and set the pH value control layer in the disinfection device to sodium dihydrogen phosphate, and control the pH value of the water passing through the disinfection device in the range of 6.5-7.0;

[0043] (3) Install the disinfection device and connect the disinfection device with the water pump, turn on the water pump, make the pond water flow through the disinfection device for disinfection, the cross-sectional area of ​​the water pipe is 0.05m 2 , The water flow velocity is 1m / s;

[0044] (4) Move the position of the water pump head in the pond every 30-40 minutes;

[0045] (5) Check the disinfection of pond water every 3 hours. During the test, take samples from the nearest to ...

Abstract

The invention discloses a water culture method used before aquaculture and belongs to the technical field of aquaculture. The water culture method comprises the following steps that 1, a pH value of pond water is determined; 2, a pH value control layer in a sterilization device is arranged according to the result determined in the step 1, and the pH value range of water passing through the sterilization device is controlled to be 6.5-7.0; 3, the sterilization device is installed and is connected with a water pump, and the water pump is started; 4, the position of a water pump head in a pond is moved at intervals of 30-40 minutes; 5, the sterilization situation of the pond water is detected at intervals of 2-3 hours, sampling is conducted on position points according to distances away from the water pump from near to far, at least five samples are measured, and the pH value, ammonia nitrogen content and nitrate content are measured; 6, sterilization is stopped according to the result measured in the step 5, algal species, fertilizers, water, EM bacteria and prebiotic bacteria are applied after 1-2 days after sterilization stopping, wherein water cyclically flows in the whole process so that the uniform sterilization situation of the water of a whole pond can be ensured and water quality detection can be more accurate.

Description

Technical field [0001] The invention belongs to the technical field of aquaculture, and specifically relates to a water cultivation method before aquaculture. Background technique [0002] The quality of water in aquaculture directly affects the survival and growth of aquatic animals. Water cultivation should be done before breeding, that is, water quality should be adjusted to meet the needs of aquaculture before breeding. [0003] Under normal circumstances, the steps for water cultivation are: pond disinfection, detoxification with organic acid products, and then fertilization to cultivate water. Pond disinfection often uses chlorine-containing preparations to disinfect the ponds, and directly sprays chlorine-containing preparations in the pond. The problem of uneven disinfection of water quality will inevitably lead to inaccurate testing during testing, and chlorine-containing preparations will cause a greater burden on the environment. Summary of the invention [0004] The pre...
