Underwater-loach and aquatic-vegetable farming method

Abstract

The invention discloses an underwater-loach and aquatic-vegetable farming method. The underwater-loach and aquatic-vegetable farming method includes the steps of construction of a farming pool, layoutof a foam floating bed, throwing of seedlings in the farming pool, sowing of vegetable on the foam floating bed and daily management. The underwater-loach and aquatic-vegetable farming method has theadvantages that loaches farmed are delicious, rich in nutrition, high in content of protein and the like, the vegetable planted absorbs nutritive substances of nitrogen, phosphorus and the like in the pool water through developed roots and by the aid of photsynthesis, and the vegetable obtained can serve as feed for the loaches and be consumed by people.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a method for cultivating underwater loach and aquatic vegetables. Background technique [0002] Since the 1990s, my country's fishery production has entered a period of rapid development, and the scale of intensification has continued to expand. Since 1990, the total output of my country's aquatic products has leapt to the first place in the world. However, high-density and intensive aquaculture also brings serious pollution to the aquaculture water. It puts a large amount of feed into the limited water body, and some excrement and feed residue are easily volatilized and decomposed under the action of microorganisms. A large amount is harmful to the survival of fish. Ammonia and nitrate, etc., lead to eutrophication and deterioration of water bodies. Water pollution promotes a large number of pathogens, which in turn causes frequent occurrence of various aquatic animal dis...

However, high-density and intensive aquaculture also brings serious pollution to the aquaculture water. It puts a large amount of feed into the limited water body, and some excrement and feed residue are easily volatilized and decomposed under the action of microorganisms. A large amount is harmful to the survival of fish. Ammonia and nitrate, etc., lead to eutrophication and deterioration of water body

Water pollution promotes a large number of pathogens, which in turn causes frequent occurrence of various aquatic animal diseases. New pathogens emerge one after another. On the one hand, the use of antibiotics can inhibit or even kill pathogens. On the other hand, it will introduce new pollution and produce new resistance. Drug strains, thus forming a vicious circle in aquaculture production, thus restricting the development of aquaculture industry
