Description

Production mode of aquaculture model and its application

The invention relates to a production device for aquaculture model and its application.

Background technique

One of the major problems currently restricting the development of agriculture is water. The depletion and pollution of the world's water resources is posing a serious threat to human beings, and it also greatly restricts the development of agriculture, because agriculture is a major water user. Therefore, the development of the aquaculture industry is a major event that cannot be delayed. The domestic and international aquaculture industry focuses on wastewater purification treatment and seawater desalination. This model is considered from the perspective of improving water utilization as an important model of the aquaculture industry. It is a new leap in theory.

In recent years, people began to consider the mutual reciprocity between biological groups. There have been several inventions and creations, but most of these inventions have the disadvantages of large and complicated systems, high production costs and low production efficiency.

Summary of the invention

The object of the present invention is to provide a production apparatus for an aquaculture model and its application, which not only contributes to improving water quality and water utilization, but also provides food and mutual food by utilizing the metabolism of aquatic plants, plants and aquatic animals. Nutrient, complementary growth and reproduction, which not only reduces production costs, but also greatly improves the quality and yield of the product, while protecting the environment.

The present invention is constructed in such a manner that it includes a fish culture pond or the like, and is characterized in that: the fish culture pond is provided with one or more layers of azolla or seaweed cultivation beds, and the fish culture pond water passes through a pump water pipe The road device transports water to the top layer of the cultivation bed and then flows through the various layers of azolla or seaweed cultivation beds, and the beds of the azolla red or seaweed cultivation bed are the bottom side with the drainage port leading to the next layer of cultivation bed. In the basin, the water surface in the basin is covered with a layer of azolla or seaweed, and the bottom bed of the azolla or seaweed cultivation bed is provided with a pipeline leading to the fish culture pond.

In use, the water of the waste water containing some fish in the fish culture pond is flowed into the filtration purification and water recovery device cabinet through the pipeline through the pump water pipeline device, and then the water is transported to the top bed of the azolla or seaweed cultivation bed, respectively Nutrient irrigation of azolla or seaweeds and plants; and the water after irrigation of azolla or seaweed flows into the next layer of water storage tanks through the drains on the bottom side of each layer of water storage basins, and finally the return line from the bottom bed Return to the fish culture pond. At the same time, in the process of nutrient irrigation of azolla red or seaweed in the pool water, because the water of the river has the function of purifying water and releasing oxygen, 'the water quality of the pool water is not only purified to a certain extent, but also the oxygen content is increased, so when it returns to After the fish culture pond, it can increase the supply of oxygen for fish growth. In this cycle, the user can cultivate azalea or seaweed with short production cycle and high nutrient content, as well as a large number of fish products and plant products under a small investment situation, which constitutes a set that is not affected by the external environment, nor does it An ecological recycling culture system that affects the external environment, is low in cost, high in yield and quality, and is basically self-sufficient in addition to fish bait.

Compared with the prior art, the invention aims at improving the water utilization rate, and achieves the ingenious combination of plants, aquatic products and animals through a complete and ingenious multi-layer breeding facility, which complements each other and complements each other, thereby fully effective on the one hand. The use of 7 "water resources has alleviated the contradiction between water resources in various regions and ensured that the environment does not cause pollution due to conventional production. On the other hand, the production and quality of aquatic plants and aquatic animals have been greatly improved, and the water utilization rate has been increased by more than 20 times. And agricultural production has increased by 10 times or even dozens of times. Its implementation and application will bring great improvement to the ecological environment, and open up a new way of stable, reliable and sustainable development for food sources, food sources and food safety. Has a significant role in invention.

detailed description

The embodiment of the present invention includes a fish culture pond 1 , characterized in that: the fish culture pond is provided with one or more layers of azolla or seaweed cultivation bed 2, and the fish culture pond water passes through a pump water pipeline device 3 After being transported to the top layer of the cultivation bed, it flows through each layer of azalea red or seaweed cultivation bed, and each layer bed of the azolla or seaweed cultivation bed is a water storage basin with a drainage port 4 leading to the next layer of cultivation bed on the bottom side. The water surface in the pot is covered with a layer of azolla or seaweed 5, and the bottom bed of the azolla or seaweed cultivation bed is provided with a return line 6 leading to the fish culture pond.

Above the bottom side of each layer of the water storage basin, there is a tubular cover 8 having a water passage hole 7 for preventing the loss of azolla or seaweed, so that the water in the water storage basin can be lowered to the lower layer and the water can be prevented or Loss of seaweeds.

The drain ports of the two upper and lower adjacent water storage basins are located on different sides.

In order to reduce the evaporation of water, the production device is arranged in a transparent cultivation shed, and the side wall of the cultivation shed is provided with an insect-proof net 9 for preventing aquatic animals from escaping and preventing insects in the fish culture pond, and is also protected in winter. A cold-proof protective film 10 and a necessary trap light are added to the insect net.

In order to filter and purify the fish culture pond water, the pump water pipeline device is provided with a filter purification sterilization and water recovery device cabinet 11, and the water in the river or the algae and the plant cultivation bed is recirculated through the bottom bed.
