Description

A fish and mulberry symbiotic circulating water three-dimensional culture system

technical field

The utility model relates to the technical field of aquaculture, in particular to a fish and mulberry symbiosis circulating water three-dimensional culture system.

Background technique

With the rapid development of aquaculture and the deepening of intensification, the water environment problems caused by aquaculture wastewater have become increasingly prominent. The deterioration of water quality has increasingly become a key factor restricting the further development of aquaculture. Building a fish-plant symbiosis system is a green, ecological, and low-cost water purification method that has emerged in recent years.

As early as 1,500 years ago, in ancient southern China and some Southeast Asian countries, such as Thailand and Indonesia, farmers raised fish in rice fields to realize the symbiotic breeding model of fish and rice. This is the fish-plant symbiosis system prototype. As people continue to deepen their research on the symbiotic system of fish and plants, the symbiotic system of fish and plants has become an industry. In the complete symbiotic system of fish and plants, it is composed of three parts: fish pond, plant cultivation pond and microbial filter. The aquaculture wastewater generated by the fish pond flows through the microbial filter, and the solid microorganisms in the water are trapped in the microbial filter. The microorganisms in the filter transform the ammonia nitrogen nitrite that is harmful to fish in the water into nitrate nitrogen. After being filtered by the microbial filter, the water carrying nutrients flows through the plant cultivation pond to be absorbed and utilized by plants, and converted into biomass, avoiding breeding Excessive accumulation of nutrients in the water body, and finally the purified water flows from the plant cultivation pond to the fish pond to achieve the purpose of purifying the water quality of the aquaculture, realizing "fish farming without changing water, planting without fertilization", and realizing "living water fish farming".

Mulberry is a deciduous tree of the genus Moraceae Moraceae, which has important economic value. Mulberry is the only source of plant feed for silkworms to successfully complete its generational reproduction; The World Health Organization is included in the list of "Top Ten Health Products in the 21st Century". At the same time, mulberry trees also have important ecological value. Due to the developed root system of mulberry trees and rapid growth, mulberry trees have strong adaptability and vitality. In recent years, mulberry trees have played an important role in ecological protection such as windbreak and sand fixation, water and soil conservation, and saline-alkali land management. In addition, studies have also shown that mulberry trees can be grown hydroponically.

Although the development of the fish-plant symbiosis system has made great progress, the fish-plant symbiosis system still has the following deficiencies: (1) The commercial scale fish-plant symbiosis system is not yet mature. According to the scale and purpose of the fish-plant symbiosis system. The fish-plant symbiosis system can be divided into small courtyard fish-plant symbiosis system and commercial scale fish-plant symbiosis system. The commercial scale fish and plant symbiosis system has high economic benefits. According to relevant statistics, the annual output value per mu of the Aviary fish and vegetable symbiosis system located in Yantai, Shandong Province is 5 times that of ordinary greenhouses. However, as the scale of the commercial-scale fish-plant symbiosis system continues to expand, the system becomes more complex. To master and use the system, it is necessary to master some knowledge and skills in related fields, including: environment, machinery, water quality control, Aquatic biology and other related knowledge; at the same time, the more complex the system, the more cost it needs to invest. Complex technology and high cost requirements restrict the development of commercial-scale fish-plant symbiotic systems. (2) Lack of symbiotic system model between fish and woody plants. Since herbaceous plants, such as most vegetables and flowers, are easier to hydroponic than woody plants, and the cycle from planting to harvesting of herbaceous plants is similar to that of aquaculture, people have studied the application of herbal plants to the symbiotic system of fish and plants More, the symbiosis system of fish and plant that people research at present is often only applicable to herbaceous plants, lacks the symbiosis system aiming at woody plants and fish.

Although there have been related researches on the hydroponics of mulberry trees, the research on the symbiosis system of fish and mulberry has not been involved. There are few studies on the hydroponic production of mulberry trees, the application of the powerful and vigorous mulberry root system to the water environment for water purification, and further exploration of its role in the restoration of water ecosystems, and no relevant reports have yet been seen. Therefore, there is a need to study a system or device suitable for the symbiosis of fish and mulberry trees.
