Shrimp-vegetable-fish three-dimensional ecological culture method

Abstract

Provided is a shrimp-vegetable-fish three-dimensional ecological culture method. The method comprises: firstly, using quick lime to clean a pond and disinfect; exposing a culture pond in the sun for one week, after water injection, putting shrimp fries in the pond, 20-30 days after putting the shrimp fries, putting grass carp, silver carp, spotted silver carp, carp, and giant freshwater prawns inthe pond; feeding South America white shrimp fodder, through observation, determining feeding amount of the fodder, not feeding fodder of other culture varieties; through a floating bed, planting water spinach on a water surface, since prawns are cultured in the pond, pond water is eutrophic, using root systems of the water spinach to absorb eutrophic substances in the pond water, applying fertilizer for the pond being not needed. Three-dimensional ecological efficiency among planted and cultured creatures is used, ecological three-dimensional effect among animals, plants, and microorganisms is used, and heterosis (antagonism) effect is used. A water surface space is fully used, nutrient substances in the water are reasonably used, incomplete decomposition of organic materials in the pondis reduced, occurrence of diseases is reduced, and comprehensive benefits of pond culture is improved. The method has little investment, and is simple in maintenance, and low in manufacturing and operation cost.

Description

technical field [0001] The invention relates to an aquaculture technology, in particular to a three-dimensional ecological cultivation method for shrimp, vegetables and fish. Background technique [0002] At present, both shrimp farming and vegetable farming have problems such as low overall efficiency and pollution to the surrounding environment. From the perspective of shrimp farming, the residual bait, debris and excreted feces in shrimp farming ponds have caused water pollution. The eutrophication will inevitably cause direct and indirect threats and damage to the aquaculture water body; that is to say, a large amount of sediment at the bottom of the pond may produce some toxic substances due to incomplete decomposition, and these substances will cause the body functions of prawns to decline , or sickness, or death, but also lead to a large number of harmful bacteria and other microorganisms, which become pathogenic bacteria, thereby reducing the output and quality of aq...
