Description

Aquatic plant planting blanket for hard bottom

technical field

The utility model relates to a water area environment ecological restoration technology, in particular to an aquatic plant planting blanket used for a hard bottom.

Background technique

With the development of urban concentration and urbanization of cities and towns, the beds and revetments of rivers, lakes, pools, canals and other water bodies are mostly treated with hardened concrete and stone, which forms "two-sided light" or "three-sided light". "Hydraulic construction mode focuses on unilateral needs such as water and soil conservation, flood control, and shipping, which not only destroys the original appearance of natural rivers from the senses, but more seriously cuts off the material, energy, and information exchanges between the water body and the land. , the species diversity of the water body is reduced, the ecosystem is severely damaged, the self-purification function of the water body is lost, the water quality deteriorates, and the beautification image of the urban water body is seriously damaged. Therefore, in the process of urban construction, how to economically, efficiently and quickly rebuild or restore the vegetation of rivers, lakes and other water bodies, and exert and improve their ecological self-purification function has far-reaching significance for the sustainable development of urban water bodies.

At present, although there are some technologies that can plant green plants on it to realize ecological reconstruction without destroying the original concrete or stone structure, such as the Chinese utility model patent (200920067131.6) "an ecological greening for stone base However, it can only solve the ecological restoration and greening of the river channel and bank shoulder retaining wall, and cannot restore the vegetation at the hardened bottom of the water body, let alone realize the vegetation system inside the water body.

Utility model content

The purpose of this utility model is to overcome the above shortcomings and provide a planting blanket of aquatic plants with simple structure, easy operation and multiple planting modes, so as to meet the needs of water bodies such as bed bottoms, revetment hardened rivers, lakes, canals, and community ponds. Planting and growth requirements of aquatic plants.

Concrete content of the present utility model is:

A kind of planting blanket for aquatic plants on hard bottom, comprising propagating carrier and reticular outer wrapping layer, described propagating carrier is the blanket block that is made of coconut fiber, and described reticular outer wrapping layer is PP net, reticular outer wrapping layer The wrapping layer is wrapped on the surface of the propagating carrier; the planting blanket is also provided with openings for planting aquatic plants.

Further, the net-shaped outer wrapping layer is combined with the propagation carrier through bonding and calendering.

Further, the vegetation blanket is at least fixed by means of stainless steel staples or weight blocks.

Further, the aquatic plants on the planting blanket are at least seed planting or dental branch planting or seedling transplantation.

The beneficial effects of the utility model are:

1. The utility model is a planting blanket made of strong affinity plant fibers and stable man-made fibers through a special process, which can provide aquatic plants with a soil-like growth propagation carrier.

2. The utility model utilizes the characteristics of "hydroponics" of plants, without providing special plant growth base, directly absorbs and utilizes nutrients (nitrogen, phosphorus, etc.) in the water body, and effectively reduces the concentration of nutrient salts in the water body.

3. In the application materials of this utility model, except that the PP net is not easy to degrade, the coconut fiber, the main part of the vegetation blanket, can be biodegraded slowly in the water body, and the nutrient salts (nitrogen, phosphorus) released by its degradation can be absorbed and utilized by aquatic plants. It effectively reduces the secondary pollution to the water body, and effectively overcomes the water body polluted by new nutrient sources caused by the planting pot or planting soil backfill method currently used in the market.

4. The planting method of the present utility model is to insert or transplant seeds, buds or seedlings into the openings of the planting blanket according to the characteristics of the plants. Seedlings can also be raised in shallow water, and then gradually transferred to the required depth and fixed position to improve plant survival rate and green surface benefits.

5. The planting blanket of the present utility model has a rough fiber surface, which provides more growth attachment surfaces for water microorganisms, and forms a complex and symbiotic growth environment for microorganisms together with the root system of aquatic plants.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

A kind of aquatic plant planting blanket for hard bottom, comprises propagating carrier 2 and reticular outer wrapping layer 1, and described propagating carrier 2 is the carpet block that is made of coconut fiber, and described reticular outer wrapping layer 1 is PP net , the net-shaped outer wrapping layer 1 is wrapped on the surface of the propagation carrier 2; the vegetation blanket is also provided with a number of openings for planting aquatic plants 4.

Furthermore, the mesh outer wrapping layer 1 is combined with the propagation carrier 2 through bonding and calendering.

Further, the vegetation blanket is at least fixed on the bottom of the riverbed by means of stainless steel U-shaped rivets 3 or weight blocks.

Further, the aquatic plants 4 on the planting blanket are at least seed planting or dental branch planting or seedling transplantation.

The utility model is suitable for vegetation restoration projects of eutrophic water bodies such as landscape pools, canals, rivers, lakes, etc., where the water velocity is not greater than 4.0m/s and the bottom or revetment is hardened.

The preferred scheme is that at first the thickness is moderate, that is, the diameter is 0.03-0.05mm, and the coconut fiber silk with a length of 15-33cm is woven into a coconut fiber blanket as the propagation carrier 2 by punching and acupuncture, and then the rope diameter is 0.5cm for use. 1. The PP net with a mesh of ^1cm is used as the mesh outer wrapping layer 1, and is combined with the coconut fiber blanket 2 by bonding and calendering. The width of the blanket is 1000-2000mm, and the length is 10000-30000mm. According to the construction needs of the site, the method of cutting a single sheet or splicing and combining multiple sheets is implemented.

The planting of aquatic plants 4 can select plant planting methods according to local climate conditions and plant adaptability. The specific operation is to first make holes on the planting blanket according to the size of the plant seeds, tooth branches or seedlings according to the growth characteristics of the aquatic plants arranged in the scene, and then insert the plant seeds, tooth branches or seedlings into the openings of the planting blanket.

After planting aquatic plants 4, the placement and fixing of the vegetation blanket is selected according to the depth of the water. The water depth H≤0.5m shall be fixed by installing one stainless steel U-shaped rivet 3 per square meter. The rivet specifications are: the length of the rivet is 10cm, and the length of the hook is 3cm. The stainless steel U-shaped rivets 3 of this specification are also fixedly connected between the vegetation blankets. If the water depth is H>0.5m, the heavy block pressing method is adopted directly, and a 3kg heavy block is selected for each square.

The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model in any form. Any modification made to the above embodiments according to the technical essence of the utility model does not depart from the technical solution content of the utility model. Any modification, equivalent change and modification still belong to the scope of the technical solution of the present utility model.
