Description

A greening method for vertically greening river embankment cliffs and its ecological floating bed

method field

The invention belongs to the technical field of river channel water purification and river embankment greening, in particular to a greening method for vertical greening of river embankment cliffs and an ecological floating bed.

background method

With the advancement of urbanization, rivers that were originally used for flood control and drainage have gradually been given the function of landscape greening. Among them, the construction of river greening has gradually attracted people's attention. River greening not only has the significance of reducing flood disasters, improving the urban environment, purifying and improving water quality and other ecological needs, but also has the significance of increasing the urban green area, enriching the urban landscape, and providing places close to nature and other humanistic needs.

At present, the commonly used plants for urban river greening are aquatic plants. Aquatic plants have a long history as ornamental plants. Life practice also shows that aquatic plants play a huge role in river greening and landscaping. Due to the wide variety of aquatic plants , Various colors, can well decorate and embellish the river. In addition, the arrangement of aquatic plants in the river has a strong purification effect on water quality.

At present, the embankments and cliffs of most urban rivers are bare, and the exposed river embankments and cliffs cannot purify water and air well, and in addition greatly reduce the overall aesthetic effect of the river. Currently, the vertical greening of river embankments and cliffs There is almost no research or report on this aspect.

Contents of the invention

For the embankments and cliffs of most of the above-mentioned current river courses are all exposed, the defects of ecological value, ornamental value and aesthetic value cannot be realized. The invention provides a greening method and an ecological floating bed for vertically greening river embankment cliffs.

A greening method for vertically greening river embankment cliffs, comprising the following steps

S1 propagating the cuttings of the hydroponic vines, and waiting for the vines to take root;

S2 fixes the support net on the cliff of the river embankment;

S3 fixes the substrate on the cliff of the river embankment below the S2 support net, fixes the planting pot containing the matrix on the substrate, and plants the vines after S1 rooting in the matrix in the planting pot. Connect and fix on the support net to form a green net;

S4 Remove yellow leaves and dry old leaves in time during the growth of vines. The greening net covers the cliffs of the entire river, and pruning is performed when the vines cover the surface of the support net.

In the technical scheme of the present application: the hydroponic vines have the characteristics of strong entanglement, well-developed aerial roots, colorful leaves, evergreen in four seasons, and drooping long branches. They are excellent foliage plants and can climb and grow. After the vines are propagated by cuttings and rooted, they are transplanted into the planting pots with a fixed substrate on the cliff of the river embankment. After the vines grow, they are connected by branches and leaves and fixed on the support net to form a greening net. During the growth of the vines, the yellow leaves and For dry old leaves, avoid consuming normal stems, leaves and soil nutrients. The greening net covers the cliffs of the entire river, and when the vines cover the surface of the supporting net, trim them to ensure air permeability, so as to purify the water body of the river and clean the river. The greening of embankments and cliffs enriches the research on the vertical greening of river embankments and cliffs in the prior art, and can greatly enhance the ecological value, ornamental value and aesthetic value of urban rivers.

Preferably, the vine is ivy or pothos. Ivy is a perennial evergreen climbing shrub with aerial roots, gray-brown or black-brown stems, smooth, alternate leaves, evergreen in all seasons; dill belongs to large evergreen vines, often climbing and growing on rocks and tree trunks in the rainforest. Strong resistance, well-developed aerial roots, can be planted in hydroponics, grows faster, and has good greening effect.

Preferably, during the formation of the greening net in S3, after the main stem of the vine grows to 1m, the branches and leaves of the vine are tied to the support net with straps, and the hydroponic vine is stretched along the support net. Growth forms a green net. The vines grow along the support net, and the support net supports and guides the growth of the stems and leaves of the hydroponic plants, so that the vines cover the entire river embankment and cliffs, forming a green network, which can greatly improve the ecological value of the urban river, viewing value and aesthetic value.

The utility model relates to an ecological floating bed obtained by a greening method for vertically greening river embankment cliffs.

Preferably, the ecological floating bed includes a support net vertically fixed on the cliff of the river embankment, a base plate fixed on the cliff of the river embankment below the support net, a plurality of planting pots placed on the base plate and located at each Lianas in the planting pots. The support net is fixed on the cliff of the embankment of the river, which is convenient for vines to climb. The substrate is used to support and fix the planting pot. The vine grows after being planted in the planting pot and grows along the support net.

Preferably, a plurality of limit frames are arranged on the base plate, and the plurality of limit frames are lined up along the river channel, and each of the planting pots is located in the limit frame. The limit frame acts as a limit to the planting pots to prevent the planting pots from shaking.

Preferably, each of the planting pots is provided with a substrate for the growth of the vines. The matrix includes leaf humus, coconut peat, sand, red loam, feces, vermiculite, perlite, etc., and is uniformly mixed according to conventional weight parts in this field.

Preferably, a plurality of straps are evenly arranged on the support net. The straps are used to tie vines so that they cover the entire support net to form a green net.

Preferably, fixing holes are drilled on the surface of the river embankment cliff where the support net is located, and the support net is fixed on the river embankment cliff by rivets. Not only is it fixed firmly but also easy to disassemble.

Preferably, the bottom of each planting pot is provided with a plurality of first through holes, and the substrate is provided with second through holes corresponding to the first through holes. The setting of the first through hole and the second through hole allows the roots of vines to grow downward under the action of gravity and go deep into the river channel. Aiming at the eutrophic water quality, the principle of ecological engineering is used to degrade COD, nitrogen and phosphorus in the water. The nutrition of the water body is transferred, and the phenomenon of stench and eutrophication of the water body caused by the closure or insufficient self-circulation of the water body is alleviated.

The ecological floating bed of the present application can also be applied to river embankment cliffs, urban wetland scenic spot cliffs, pond cliffs, etc., to purify water and air, and realize its ecological value, ornamental value and aesthetic value.

In the method scheme of this application:

Compared with existing methods, the beneficial effects of the present invention are:
