Self-circulating cultivation method compounding fruits and vegetables and aquaculture ecological water

Abstract

The invention relates to the technical field of fruits and vegetables and aquaculture, in particular to a self-circulating cultivation method compounding fruits and vegetables and aquaculture ecological water. The self-circulating cultivation method is characterized in that the ecological water in an aquaculture pond after feeding is absorbed and decomposed by fish, shrimps and crabs to obtain primary circulating liquid, the primary circulating liquid is sequentially subjected to sterilizing, microbial water purification and oxygen dissolving and then returns to the aquaculture pond, the restof primary clean liquid subjected to electrodialysis returns to the aquaculture pond, and the obtained suspension nutrient solution returns a water culture pipe from the head part of the water culturepipe. Compared with an existing fish-plant symbiotic cultivation method, the self-circulating cultivation method has the advantages that the yield of fish, shrimps and craps is increased by 20-30%, the production cycle is shortened by 1-2 months, the aquaculture water is clear and free of pollution, and aquaculture water quality is well controlled and greatly improved; the yield of the fruits andvegetables is increased by 10-20%, the fruits and vegetables are good in growth vigor and high in disease resistance, fruit fullness is achieved, dining table diet is greatly enriched, and the safetyof dining table food such as the fruits and vegetables, the fish, the shrimps and the crabs is guaranteed.

Description

technical field [0001] The invention relates to the technical field of fruits, vegetables and aquaculture, and relates to a compound self-circulating cultivation method of fruits, vegetables and aquatic ecology. Background technique [0002] At present, domestic fruit and vegetable planting and aquaculture are mostly independent systems, and traditional planting and breeding methods are still the main method. The long-term unreasonable and excessive use of chemical fertilizers and pesticides in the fruit and vegetable planting industry is common, and there are great hidden dangers in food safety; aquaculture industry Most of them are based on pond culture, which is greatly affected by natural factors such as climate and water quality. There are water pollution phenomena caused by bait, fish excrement, and untimely water changes, which are relatively destructive to the surrounding water environment; in recent years Some fish-plant symbiosis breeding methods have also appeared...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a compound self-circulating breeding method of fruits and vegetables and aquatic ecological water, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the hidden dangers of food safety in the traditional fruit and vegetable planting industry, water pollution in the aquaculture industry, and the symbiosis of fish and plants. The water quality is not easy to control and unstable in the breeding method, and the yield of aquatic products and fruits and vegetables is low, which restricts the development of fruit and vegetable planting and aquaculture in the direction of intensive ecological agriculture.
