Problems solved by technology

In areas with considerable wind and waves (the average wave height is greater than 10cm), due to the up-and-down motion of the waves, the roots, stems and leaves of floating plants are rubbed against each other and damaged. In the natural state, the amount of damage is much greater than the

Embodiment Construction

[0011] see figure 1 , the floating plant floating bed monomer with mesh bag structure, considering the convenience of processing and cost reduction, the mesh with a width of less than 400cm is more suitable. If the net is too wide, subsequent processing is inconvenient; if the net is too narrow, the cost of subsequent processing will increase after a certain scale. Tests have shown that if the mesh is too large, the roots and stems of plants will easily escape under the action of wind and waves; if the mesh is too small, it is not conducive to the stems and leaves of plants to pass through the mesh and affect their growth. Aged nets with knots are more suitable (for example, No. 7 fishing nets, 3*4 strands); choose Amaranthaceae and Lianzia as floating plants, and wrap them in mesh bags with a hole of 2 to 3 cm in the planting method. , fixed to the bottom of the water with stakes, ropes or gabions. The planting time should be selected when the lotus seeds have not germinate...

Abstract

The method of utilizing floated plant bed to treat wind wave eutrophic lake area features that Alternathera philoxeroides is planted onto floating carrier to form floated plant bed fixed to the water surface. The floated plant bed consists of several strips with Alternathera philoxeroides, preferably planted before or just after germination. The floating carrier may be netted bags with floated plant and is fixed with piles, ropes or stone cages to water bottom. The floating carrier may also be bamboo raft with Alternathera philoxeroides and fixed with piles and ropes to water bottom.

Description

technical field [0001] The invention relates to the control of eutrophication in the stormy area of ​​a lake, in particular to a method for controlling the eutrophication in the stormy area of ​​a lake by using a floating plant floating bed. Background technique [0002] The eutrophication of lakes and other water bodies is a very serious environmental problem facing the world at present, and it is especially serious in our country, especially in economically developed areas where there is a problem of water quality and water shortage. Floating plants are used as pioneer plants to build a good water ecosystem and are widely used in the purification and treatment of eutrophic water bodies, such as US patents 5820759, 5811007, Chinese patents CN1425616, CN1426966, CN1552641, CN1580415, and CN1683258. Most of the floating plants used are Water hyacinths are all in water bodies without wind and waves, such as rivers, river beaches, ponds, lake bea...
