Problems solved by technology

The input of artificial feed causes serious environmental pollution caused by intensive farming. In terms of freshwater aquaculture, the feces produced by raising 1 ton of freshwater fish is equivalent to the amount of feces produced by 20 pigs. In terms of mariculture, each ton of shrimp needs to be cast Feed is 3 to 5 tons, which is equivalent to 1 ton to 1.3 tons of protein, but the utilization rate is only about 20%. A large amount of nitrogen flows into the water body, causing secondary pollution of the breeding waters
At the same time, due to the large amount of wastewater involved in this feeding method, water treatment and pollution control are more difficult
In addition, as inland water bodies and coastal waters are affected by industrial, civil and agricultural pollution, the water quality deteriorates, affecting its applicability for aquaculture, resulting in a further reduction in available water sources

preparation example

[0023] Drainage plate, its preparation method is as follows:

[0024] Mix 7 kg of river channel dredging sediment with 3 kg of cement, stir at room temperature at a speed of 120 r / min for 4 minutes, then add water to adjust the solid content to 0.35, then stir at a speed of 65 r / min for 1.5 min, then add 0.36 kg of frequency Nacohol borane and 0.18 kg of bistrifluoromethanesulfonimide, then stirred at a speed of 85 r / min for 1.5 min; then added 0.24 kg of bismuth sulfide, and continued to stir for 1 min to obtain a mixture; then the mold was placed on a vibrating table above, with an amplitude of 4 mm, the mixture was cast in a mold, mechanically vibrated until the mold was filled, and then vibrated for 4 minutes; after the casting was completed, the mold was demoulded to obtain a test piece; the test piece was sprayed and cured for 28 days to obtain Drainage plate; the water content of the dredged sediment of the river is <10%, and the particle size is 100-200 mesh; the drain...

Embodiment 1

[0027] A shrimp vegetable rotation ecological culture pond, comprising a sedimentation pond 1, a filter pond 2, a purification pond 3, a cultivation pond 4, and an aeration device 5; a grid 6 is provided between the sedimentation pond and the cultivation pond; the purification pond and the A water pump 7 is provided between the breeding ponds; the filter tank is located between the sedimentation tank and the purification tank; the sedimentation tank is provided with a first partition 11, a second partition 12, a third partition 13; the first partition plate, the second partition, and the third partition are arranged in sequence; the first partition is located at the grid; the bottom surface of the first partition is higher than the bottom surface of the sedimentation tank; the top surface of the second partition is lower than the sedimentation tank Top surface; the bottom surface of the third partition is higher than the bottom surface of the sedimentation tank, thereby forming...

Embodiment 2

[0030] On the basis of Embodiment 1, according to the existing installation method, the sedimentation tank is equipped with water body oxygen content detection equipment; the breeding pond is equipped with water temperature detection equipment; the purification tank is equipped with water body organic element detection equipment. Through the positioning setting of the water body oxygen content detection equipment, the oxygen capacity in the breeding pond can be accurately detected, providing a basis for oxygenation, and through the positioning setting of the water temperature detection equipment, the temperature of the breeding pond can be accurately detected, giving reasonable conditions for breeding, and organic elements in the water body The detection intuitively tells the pond owner the self-circulation effect.

Abstract

The invention discloses an ecological breeding pond for shrimp and vegetable crop rotation. The ecological breeding pond comprises a settling pond, a filtering pond, a purifying pond, a breeding pondand an oxygen increasing device. A grid is installed between the settling pond and the breeding pond; a water pump is installed between the purifying pond and the breeding pond; the filtering pond isinstalled between the settling pond and the purifying pond; a high water opening is form between the settling pond and the filtering pond; a low water opening is form between the filtering pond and the purifying pond; the oxygen increasing device is located at the water outlet of the water pump; the purifying pond is provided with an external water pipe; a sludge layer with the thickness of 0.2-0.4 meters is installed at the bottom of the breeding pond; the pond bank slope ratio of the breeding pond is 1:2.5. On one hand, the characteristic of strong fertilizer absorption ability of vegetablesof broccoli, potherb mustard, brassica juncea var.tumida and the like is used to hardening sludge and to reduce organic materials in the pond, and on the other hand, residue leaves after growing period of the vegetables are used to provide an excellent condition for the growth of South America white shrimps; meanwhile, the vegetables of the broccoli, the potherb mustard, the brassica juncea var.tumida and the like greatly improve output effect of the pond. Not only is the land utilization efficiency improved, but also the output effect of unit area farmland is greatly improved.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a novel shrimp-vegetable rotation ecological breeding pond. Background technique [0002] With the expansion of market demand for aquatic products, aquaculture has achieved rapid development by catering to people's growing demand for aquatic products with its huge development potential. The vigorous development of aquaculture and the continuous expansion of aquaculture scale; With the rapid development, the aquaculture area is gradually expanding, leading to a series of environmental problems, such as the decline in the utilization rate of land resources brought about by the continuous development of new aquaculture ponds for freshwater aquaculture, and the high nitrogen and phosphorus content in the bottom mud of shrimp ponds often makes the The impact on the water quality of shrimp ponds has become a matter of great concern to the country and the industry. Excessive pond...
