Problems solved by technology

However, the existing floating bed materials hinder the gas exchange between the surface of the water body and the atmosphere, which is not conducive to the natural reoxygenation of the water body, which can lead to a significant drop in the dissolved oxygen in the water quality in the floating bed area, affecting the survival of cultured organisms
Moreover, the cost of the floating bed carrier is high, the recycling rate is low, and it is not conducive to the periodic seasonal connection of breeding, and the waste is serious

Embodiment 1

[0015] Example 1: A method of the present invention for restoring floating bed plants in aquaculture pond environment adopts the following process steps:

[0016] In the present invention, a soilless cultivation water spinach (Ipomoea aquatica Forsk) with nylon material fishing net as a floating bed carrier is placed on the water surface of a fish breeding pond, thereby completing the construction of a floating bed plant system in the pond.

[0017] The fish breeding pond of the aquatic product breeding farm in Hongze County, Jiangsu Province covers an area of ​​7.5 mu. The pond is surrounded by cement board slope protection, the bottom is soil, and the water depth is more than 1.5 meters. A floating bed plant system for cultivating water spinach without soil is built on the surface of the pond. The area accounts for 5% of the entire pond: a nylon fishing net with a length of 5 meters and a width of 2 meters is used as a carrier, which is tightened and fixed with lead wires. A flo...

Embodiment 2

[0019] Embodiment 2: The present invention is a method for restoring floating bed plants in aquaculture pond environment, using the following process steps:

[0020] The fish breeding pond of the aquatic product breeding farm in Hongze County, Jiangsu Province covers an area of ​​7.5 mu. The pond is surrounded by cement board slope protection, the bottom is soil, and the water depth is more than 1.5 meters. A floating bed plant system for growing water spinach without soil is built on the surface of the pond, which accounts for 10% of the entire pond: a nylon fishing net with a length of 5 meters and a width of 1.5 meters is used as a carrier, which is tightened and fixed with lead wire A floating bed is formed on a rectangular bamboo frame or wooden fixed bracket; cut the water spinach obliquely at the branches, and plant 3-5 strains into the mesh of the fishing net, whichever is filled with the mesh, the mesh diameter is 1.5cm; because of the mesh To ensure the growth of plants,...

Embodiment 3

[0022] Embodiment 3: A method of the present invention for restoring floating bed plants in aquaculture pond environment adopts the following process steps:

[0023] The fish breeding pond of the aquatic product breeding farm in Hongze County, Jiangsu Province covers an area of ​​7.5 mu. The pond is surrounded by cement board slope protection, the bottom is soil, and the water depth is above 1.5 meters. A floating bed plant system for growing water spinach without soil is built on the surface of the pond, which accounts for 8% of the entire pond: a nylon fishing net with a length of 4 meters and a width of 2 meters is used as a carrier, which is tightened and fixed with lead wires. A floating bed is formed on a rectangular bamboo frame or wooden fixed bracket; cut the water spinach obliquely at the branches, and plant 3-5 strains into the mesh of the fishing net, whichever is filled with the mesh, the mesh diameter is 1.5cm; because of the mesh To ensure the growth of plants, the ...

Abstract

The invention relates to floating bed plant method for repairing the aquiculture pond environment, which is characterized in that a floating bed plant system is constructed on the aquiculture pond water surface; the plates are planted without soil and the culture ecologic environment is repaired. The method comprises following steps: taking the fishing web made of nylon material as the carrier, tightening, fixing on a bamboo frame or a wood support by the lead wire; planting the plants into the meshes of the fishing net until filling the meshes; arranging a liner web on the bamboo frame or the wood support for protecting the plants; finally putting the floating bed with plants on the pond water surface. The invention solves the defects of the former floating bed carrier, ensures the gas exchange between the floating bed zone water surface and the atmosphere, enhances the atmosphere reaeration, increases the dissolved oxygen content in the floating bed zone water, improves the purification effect of the floating bed plants to the water and greatly boosts the quality and benefit of the pond culture.

Description

Technical field [0001] The invention relates to a new type of floating bed plant method for repairing the environment of aquaculture ponds, in particular to the technical field of aquaculture. Background technique [0002] At present, pond aquaculture in our country occupies a pivotal position in the fishery economy. Most of the existing pond culture is traditional culture mode, that is, high-yield culture mode with high density and large amount of fertilization. In order to increase the production of aquaculture per unit of water, one-sided pursuit of high yields often excessively increase water nutrition, overfeed, fertilize and increase stocking density, resulting in the accumulation of residual bait in the water and the metabolic excrement of cultured species, and organic matter in the water. The content of nitrogen and phosphorus soared, water quality deteriorated and pollution was serious. With the gradual improvement of the country's requirements for water resources manage...
