Problems solved by technology

At present, the existing problem is that there are not many research results on the relationship between vegetable types, planting area and growth conditions, and the effect of water quality regulation, and the growth of plants will consume oxygen in the water, which will affect the growth of shrimp (fish, crab)
[0007] At present, due to the lack of effective unit integration, only relying on a simple combination of one or several water quality control technologies can no longer meet the control requirements of low-carbon, ecological and green aquaculture water quality in closed water bodies

Embodiment 1

[0054] Experimental breeding pond: The area of ​​the breeding pond is 5 mu. The pond is surrounded by cement board slope protection, the bottom is soil, and the water depth is more than 1.5 meters. The test equipment configuration is attached figure 1 shown. Specifically, one set of central control unit 0, two sets of gas input unit 2, two sets of water quality monitoring unit 3, and a set of 4 floating bed plant units for planting water spinach on the water surface of the pond, accounting for 10% of the entire pond. The unit start-up time of the present invention is 8 hours / day (9:00~10:00 in the morning altogether 1 hour, inject oxygen-enriched air; 13:00~14:00 respectively in the afternoon inject ozone-anion oxygen altogether 1 hour; Evening 22:00 ~ 4:00 the next day to inject oxygen-enriched air for a total of 6 hours), and regularly harvest the water spinach of the floating bed plant unit. 80,000 vannamei seedlings / mu were cultured in the pond, and the test period was f...

Embodiment 2

[0058] Experimental breeding pond: The area of ​​the breeding pond is 7 mu. The pond is surrounded by cement board slope protection, the bottom is soil, and the water depth is more than 1.5 meters. The test equipment is configured as figure 2 shown. Specifically, one set of central control unit 0, two sets of gas input unit 2, two sets of water quality monitoring unit 3, and two sets of floating bed plant unit 4 for planting water spinach on the water surface of the pond, accounting for 20% of the entire pond. The unit start-up time of the present invention is 10 hours / day (9:00~10:00 in the morning altogether 1 hour, injects oxygen-enriched air; Each 13:00~14:00 in the afternoon totally 1 hour, injects ozone-anion oxygen; Evening 21:00 00 to 5:00 the next day for a total of 8 hours, injecting oxygen-enriched air), and harvesting water spinach on the floating bed regularly. 80,000 vannamei seedlings / mu were cultured in the pond, and the test period was from June 20 to Augus...

Embodiment 3

[0062] Experimental breeding pond: The area of ​​the breeding pond is 9.5 mu. The pond is surrounded by cement board slope protection, the bottom is soil, and the water depth is more than 1.5 meters. The test equipment is configured as image 3shown. Specifically, one set of central control unit 0, two sets of gas input unit 2, two sets of water quality online monitoring unit 3, and three sets of floating bed plant unit 4 for planting water spinach on the water surface of the pond, accounting for 30% of the entire pond . The starting time of the equipment of the present invention is 12 hours / day (9:00~10:00 in the morning for 1 hour, inject oxygen-enriched air; respectively 13:00~14:00 for 1 hour in the afternoon, inject ozone-negative ion oxygen; evening 20:00 00 to 6:00 the next day for a total of 10 hours, injecting oxygen-enriched air), and harvesting water spinach on the floating bed regularly. 80,000 vannamei seedlings / mu were cultured in the pond, and the test period...

Abstract

The invention discloses an aquaculture water quality regulation system disposed in closed water. The system includes: a gas input unit and a floating bed plant unit. The gas input unit is arranged on the surface of the closed water, and is used for conveying gas-liquid dispersions into the closed water and providing water flow power to the closed water. The floating bed plant unit is suspended at the surface for the closed water to absorb nitrogen and phosphorus in the closed water. The invention also discloses an aquaculture water quality control method, which can provide a good water environment for aquaculture of shrimps, fish, crabs and the like, and also can makes use of the excreta of shrimps, fish, crabs and the like to produce green organic vegetables. The system and the method provided in the invention not only provide a good water environment for aquaculture, improve the yield and quality of aquatic products, but also can produce large amounts of green organic vegetables, thus realizing effective utilization of resources.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an aquaculture water quality control system and control method. Background technique [0002] Closed water aquaculture is the main way of aquaculture in my country. In 2010, the area of ​​closed water aquaculture was 2.377×10 6 hm 2 , the aquaculture output is 38.2884 million tons, accounting for 71.26% of the total aquatic product output (according to the 2010 National Fishery Economic Statistical Bulletin). my country's closed water aquaculture began in the 1970s, and the aquaculture is mainly based on the open material flow mode of "resource consumption-product production-waste discharge". In recent years, with the improvement of the breeding level, the catch of fish and shrimp per unit of water body has increased, the amount of feed input has increased, the amount of residual bait in closed water bodies has increased, and the accumulation of metabolites of shrimp (fish,...
