Problems solved by technology

However, this large-scale breeding method not only needs to consume a large amount of "new water" to replenish pond water to maintain a stable water level, but also the aquaculture wastewater discharged from shrimp ponds generally contains more nutrients such as nitrogen and phosphorus, which easily leads to eutrophication in the receiving water. It has become the main source of pollution in the adjacent

Embodiment 1

[0024] A kind of high-efficiency ecological culture system of shrimp deep pool greenhouse, such as figure 1 As shown, it includes a greenhouse 1, a small shed 2, a standard thick pond 3, a growing pond 4, an ecological purification pond 7, a seedling guide channel 5 and a sewage pipeline 6, wherein the small shed 2 is located in the greenhouse 1, and the The standard thick pond 3 is connected to the cultivation pond 4 by the seedling guide channel 5, and the cultivation pond 4 is connected to the ecological purification pond 7 by the sewage pipeline 6, and the standard thick pond 3 is formed on the described cultivation pond 4 height difference.

[0025] The standard thick pool 3 is located in the small shed 2, with an area of ​​100-800m 2 , the water depth is 0.5-1.5m, the salinity is 2‰, the slope of the pool wall is 1:3-5, and the solar radiation can be used to raise and maintain the temperature of the pool water.

[0026] The growing pond 4 is located outside the shed 2 ...

Embodiment 2

[0029] The cultivation method based on the cultivation system described in embodiment 1 is as follows:

[0030] (1) In the middle of March, to an area of ​​300m 2 1. The small shed standard rough pond with a slope of 1:3 is cleaned and cleaned, the salinity is 1.5‰, and the return water is sterilized at 0.8m. After the toxicity of the disinfectant disappears, 1200 macrobrachium rosenbergii seedlings of 0.8-1.2cm are stocked / m 2 , add fresh water to 1.5m in time, and after 30 days of temporary cultivation, the body length of shrimp seedlings can reach about 4.5cm. The growth pond is cleared, sorted, and disinfected after returning to 0.5m. The greenhouse uses solar radiation to improve and maintain Pool water temperature, after the pool water temperature rises to 20°C, until the toxicity of the disinfection drug disappears, using the natural drop between the standard thick pool and the grow-out pool, the shrimp seedlings are introduced into the area of ​​3000m2 through the seed...

Embodiment 3

[0033] The cultivation method based on the cultivation system described in embodiment 1 is as follows:

[0034] (1) Early March, to an area of ​​500m 2 1. The small shed standard thick pond with a slope of 1:4 is cleaned and cleaned, the salinity is 1.8‰, and the return water is sterilized at 0.6m. After the toxicity of the disinfectant disappears, 1300 macrobrachium rosenbergii seedlings of 0.8-1.2cm are stocked / m 2, add fresh water to 1.5m at the right time, and after 30 days of temporary cultivation, the body length of shrimp seedlings can reach about 4.2cm. Pool water temperature, after the pool water temperature rises to 20°C, until the toxicity of the disinfection drug disappears, the shrimp seedlings are introduced into the area of ​​2500m2 through the seedling guide channel and the water by using the natural drop between the standard thick pool and the grow-out pool 2 , the water depth is 1.2m, and the slope of the pool wall is 1:2, the density of seedlings is 105 / m ...

Abstract

The invention discloses a shrimp deep pool greenhouse efficient ecological breeding system and method. The system is composed of a standard coarse pool shed with the area being 100-800 m<2> and the water depth being 0.5-1.5 m, a growing pool greenhouse with the area being 600-7,000 m<2> and the water depth being 2.0-5.0 m and a shed outside ecological purification pool with the area being 400-2,000 m<2> and the water depth being 1.5-2.5 m. Accordingly, by means of standard coarse pool shed and growing pool greenhouse temperature raising, early seedling placing, multiple stocking and multiple fishing (multiple cropping culture), harvesting delaying and growing pool depth increasing, the purposes of efficiently utilizing places for breeding, being stable in water environment and achieving astagger market of finished products are achieved, breeding waste water is input in an ecological pool to breed high-value aquatic animals or plant high-value aquatic plants so as to be purified for reutilization, and then an efficient, circulating and ecological multi trophic level shrimp breeding mode is built.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a high-efficiency ecological culture system and a culture method for shrimps in a deep pool greenhouse. Background technique [0002] With the rapid development of my country's aquaculture industry, the pond intensive culture method of "inlet channel + culture pond + drainage channel" has become the most important shrimp farming mode in my country. Due to the high stocking density and large amount of bait in the conventional intensive farming mode, a large amount of residual bait and metabolic waste accumulate in the aquaculture water body and the bottom of the pond during the aquaculture process, which can easily lead to high levels of toxic and harmful substances such as COD and ammonia nitrogen in the aquaculture environment, and water quality deterioration , so that the problem of environmental pollution has become increasingly prominent, and diseases of farmed shrimps ...
