Description

Vegetable cultivation and nutrition supply device and cultivation method

Technical Field

The invention relates to a vegetable cultivation and nutrition supply device and a cultivation method, and belongs to the technical field of vegetable planting and fish culture.

Background

The fish and vegetable symbiosis is a novel composite cultivation system, two originally completely different farming techniques, namely aquaculture and hydroponic cultivation, are combined through a smart ecological design to achieve scientific synergistic symbiosis, so that the ecological symbiosis effect that water is not changed during fish cultivation and water is not worried about, and plants are not fertilized to normally grow is achieved. In traditional aquaculture, ammonia nitrogen in the water body is increased along with the accumulation of fish excrement, and the toxicity is gradually increased. In the fish-vegetable symbiotic system, aquaculture water is conveyed to a water culture system, ammonia nitrogen in the water is decomposed into nitrite by bacteria and then is decomposed into nitrate by nitrobacteria, and the nitrate can be directly absorbed and utilized by plants as nutrition. The fish and vegetable symbiosis enables animals, plants and microorganisms to achieve a harmonious ecological balance relationship, is a sustainable circulation type zero-emission low-carbon production mode, and is the most effective method for effectively solving the agricultural ecological crisis.

However, in recent years, the phenomenon of meat quality reduction commonly occurs while the yield of grass carp culture is increasing. However, with the improvement of living standard, people's consumption demand for fish meat has been shifted from a quantitative type to a quality type, and a variety with excellent muscle quality is more favored by consumers. Especially, the grass carp eating mint can effectively remove the fishy smell, and has special fresh fragrance when being eaten. In order to improve the quality of the grass carps and realize the maintenance of ecological balance, a cultivation and planting mode for improving the cultivation and planting benefits is provided by utilizing a vegetable cultivation and nutrition supply device and a cultivation method.
