Method for plating water hyacinth with control in open water

Abstract

The invention discloses a method for controllably breeding water hyacinth in an open water body, belongs to the aquatic plant breeding technical field, and also belongs to the environmental protection technical field which utilizes aquatic plants to govern open water eutrophication. In the method, wave attenuation floating beds are employed to controllably breed the water hyacinth in the open water body, machinery is employed for salvage, the best stocking number is not less than 500kg per mou, the water body is kept a certain interchangeability after stocking, a firm floating movable fence (wave attenuation floating bed partition) is employed while stocking, the wave attenuation floating beds can automatically rise and fall with the water level, and are made of foam ball floats, steel tubes, meshes, iron anchors, sinkers and net ropes, the fence is formed with the wave attenuation floating beds according to specific situations of the lake surface, the fence area is controlled at 1 / 3 of the water surface area, the fence area of a wave attenuation floating bed is controlled at 100 mou, the breeding area of the water hyacinth is controlled at 1 / 4-1 / 3 of the area of the wave attenuation floating beds; and the water hyacinth is salvaged and utilized, and is made into an organic fertilizer by combining with sludge of sewage treatment plants.

Description

technical field [0001] The method for controlling the cultivation of water hyacinth in open water belongs to the technical field of aquatic plant cultivation, and at the same time belongs to the technical field of environmental protection for using aquatic plants to control eutrophication in open water. Background technique [0002] In the past, water hyacinths were planted in open water bodies similar to Taihu Lake. Water hyacinths were planted in fences made of moso bamboo piles + mesh. The net is 2m high and 1m above and below the water. The area of ​​a fence is controlled at about 2 acres. Put an appropriate amount of water hyacinth seedlings into the fence, and the water hyacinth grows naturally. Before the water hyacinth withers, the water hyacinth is salvaged ashore by manual salvage. [0003] This water hyacinth planting technique in the past has many drawbacks. One is that in open water bodies, the fence made of moso bamboo piles + mesh cannot resist typhoons and...

AI Technical Summary

Problems solved by technology

One is that in open water bodies, the fence made of moso bamboo piles + mesh cannot resist typhoons and is easily severely damaged by typhoons; The water hyacinth escapes; the third is that the fence cannot rise and fall with the water level, and when the water level rises, it will easily cause a large area of ​​water hyacinth to overflow; the fourth is that the salvage method is manual, which is inefficient and expensive
