Embodiment 1

[0032] Embodiment 1 A kind of method for reducing the high nitric acid content of greenhouse culture shrimp, comprises the following steps:

[0033] Step 1: Tunshui

[0034] Collect well water, tidy up the 20-acre big pond, pump the well water into the big pond water, and let it stand in the sun for 20 days; river water cannot be used because there is a large amount of nitrite in the river water;

[0035] Said use of well water twice; said first collection of well water, drilling depth 380m, deep well water, salinity 0.6‰;

[0036] The second collection of well water, drilling depth of 160m, getting brine brine is 26% brine;

[0037] After the collection, the primary well water and the secondary well water are mixed, and a 1.5kw aeration machine is used for each mu. The pH of the mixed water is pH7.7; the water depth of the shrimp pond is 2-4cm.

[0038] Step 2: Building the Pool

[0039] After collecting water, build a pool in the shed; build a pool in the shed; the water ...

Embodiment 2

[0057] Embodiment 2 A method for reducing the high nitric acid content of shrimp cultured in greenhouses, comprising the following steps:

[0058] Step 1: Tunshui

[0059] Collect well water, tidy up 15-20 acres of big ponds, pump the well water into the big pond water, and let it stand in the sun for 20-30 days; river water cannot be used because there is a large amount of nitrite in the river water;

[0060] Said use of well water twice; said first collection of well water, drilling depth 380m, deep well water, salinity 0.5‰;

[0061] The second collection of well water, drilling depth of 160m, taking brine brine is 19% brine, preferably 22% brine;

[0062] After the collection, the primary well water and the secondary well water are mixed, and a 1.5-2kw aeration machine is used per mu. The pH of the mixed water is pH8.3; the water depth of the shrimp pond is 2cm.

[0063] Step 2: Building the Pool

[0064] After collecting water, build a pool in the shed; build a pool in t...

Abstract

The invention provides a method for reducing the high nitric acid content of shrimp culturing in greenhouse. The method comprises the step of water storing up, the water storing-up step includes collecting well water, finishing a large pond of 15-20 mu, pumping well water to a large pond water using a pump, and standing under the sun for 20-30 days; the collecting of well water is divided into two times, in the first time of collecting the well water, a well with a depth of 380-420 m is dug, and the deep well water with a salinity of 0.4%-0.6% is taken; in the second time of collecting the well water, a well with a depth of 160-200 m is dug, and brine water with bittern of 18-26 % is taken. By adoption of the method for reducing the high nitric acid content of shrimp culturing in greenhouse, the content of nitric acid in the culture process can be effectively inhibited, so that the content of nitric acid in the water body can be stabilized within 0.3 ppm; the yield and survival rate of shrimp culture are increased by a large extent, the survival rate reaches 95% or above; the incidence of shrimp disease is reduced at a later period, in particular the prevention of intestinal diseases of shrimp reaches 100%.

Description

technical field [0001] The invention relates to the field of farming, in particular to a method for reducing the high nitric acid content of shrimp cultured in greenhouses. Background technique [0002] At present, many shrimp farmers do not pay much attention to the presence of nitrite in shrimp ponds. It is different now. The more shrimps are raised, the more they are raised, and the denser they are raised. As a result, a large number of shrimps die in the late stage of raising shrimps, or even fail. After testing, I found out that it was the nitrite in the water. Since then, attention has been paid to the presence of nitrite. As the saying goes, once bitten by a snake for ten years, you are afraid of grass ropes. There is a feeling of turning pale when talking about nitrite. [0003] Nitrite is a product of severe pollution. In aquaculture, process control, water quality, surplus bait, shrimp feces, algae and plankton carcasses and other nutrient-rich organic matter ...
