Disclosure of Invention

Aiming at the defects that most of the embankment cliff walls of the river are exposed at present and cannot realize the ecological value, the ornamental value and the aesthetic value. The invention provides a greening method for vertically greening riverway embankment cliff and an ecological floating bed thereof.

a greening method for vertically greening river bank cliff includes the following steps

S1, cutting and propagating the water culture liana, and waiting for the liana to root;

S2, fixing the supporting net on the cliff wall of the river bank;

S3, fixing a base plate on the cliff wall of the river bank below the S2 supporting net, fixing a planting pot containing a matrix on the base plate, planting the liana rooted in S1 in the matrix in the planting pot, and connecting and fixing the liana on the supporting net through branches and leaves to form a greening net after the liana grows;

S4 removing yellow leaves and dried old leaves in time during the growth process of the lianas, covering the cliff wall of the whole river channel with the greening net, and pruning when the surface of the supporting net is full of the lianas.

In the technical scheme of the application: the water culture liana has the characteristics of strong winding property, developed air roots, gorgeous leaf color, evergreen in four seasons, long-branch drape and the like, is an excellent foliage plant, can grow in a climbing manner, firstly, after the water culture liana is subjected to cuttage propagation and rooting, transplanting the vine into a planting pot of a fixed substrate on the cliff wall of the river bank, connecting and fixing the vine on a supporting net through branches and leaves to form a greening net after the vine grows, removing yellow leaves and dried old leaves in time during the growth process of the lianas to avoid consuming the nutrient components of normal stems and leaves and soil, covering the cliff wall of the whole river channel with a greening net, pruning when the surface of the supporting net is full of the lianas to ensure air permeability, purifying the water body of the river channel, the method has the advantages that the cliff wall of the river bank is greened, the research on the vertical greening aspect of the cliff wall of the river bank in the prior art is enriched, and the ecological value, the ornamental value and the aesthetic value of the urban river can be greatly improved.

Preferably, the vine is ivy or scindapsus aureus. The ivy is perennial evergreen climbing shrub, aerial roots, stem gray brown or black brown, smooth, single leaf alternate, evergreen in four seasons; the scindapsus aureus belongs to a large evergreen vine plant, grows on rocks and trunks of rainforests in a climbing mode, is strong in winding performance, developed in air roots, capable of being planted in a water culture mode, fast in growth and good in greening effect.

Preferably, in the greening net forming process in S3, after the main stem of the vine grows to 1m, the branches and leaves of the vine are tied to the supporting net by using a binding band, and the water planting vine grows along the supporting net to form the greening net. The liana grows along the supporting net, and the supporting net plays a role in supporting and guiding the growth of stem leaves to the hydroponic plants, so that the liana is covered on the cliff wall of the whole river bank to form a greening net, and the ecological value, the ornamental value and the aesthetic value of the urban river can be greatly improved.

An ecological floating bed obtained by a greening method for vertically greening riverway embankment cliff.

Preferably, the ecological floating bed comprises a supporting net vertically fixed on a cliff wall of a river bank, a base plate fixed on the cliff wall of the river bank below the supporting net, a plurality of planting pots arranged on the base plate and vine plants positioned in each planting pot. The supporting net is fixed on the cliff wall of the river bank, vine plants can climb conveniently, the base plate is used for supporting and fixing the field planting pot, and the vine plants grow after being planted in the field planting pot and grow along the supporting net.

preferably, a plurality of limiting frames are arranged on the base plate in a straight line along the river course, and each planting pot is located in the limiting frames. The limiting frame has a limiting effect on the planting pot and prevents the planting pot from shaking.

Preferably, a matrix for the growth of the vine plants is arranged in each planting pot. The substrate comprises leaf mold, coconut chaff, sand, red loam, excrement, vermiculite, perlite and the like, and is uniformly mixed according to the conventional parts by weight in the field.

Preferably, a plurality of straps are uniformly arranged on the supporting net. The bandage is used for tying the liana so as to cover the whole supporting net to form a greening net.

Preferably, the surface of the river bank cliff wall on which the support net is located is drilled with fixing holes, and the support net is fixed on the river bank cliff wall through rivets. Not only fixed firm still conveniently dismantles.

Preferably, a plurality of first through holes are formed in the bottom of each planting pot, and second through holes corresponding to the first through holes are formed in the substrate. The arrangement of the first through holes and the second through holes enables the roots of the lianas to grow downwards under the action of gravity and to go deep into a river channel, and COD, nitrogen and phosphorus in water are degraded by using the principle of ecological engineering aiming at eutrophic water quality, so that the nutrition of the water body is transferred, and the phenomena of fishy smell and eutrophication of the water body caused by the shortage of sealing or self-circulation of the water body are reduced.

the ecological floating bed can also be applied to riverway bank cliff walls, urban wetland scenic spot cliff walls, pond cliff walls and other places, is used for purifying water bodies and air, and realizes ecological value, ornamental value and aesthetic value.

In the method scheme of the application:

Compared with the prior art, the method has the beneficial effects that:

(1) Firstly, water-cultured liana plants are transplanted into a planting pot of a fixed substrate on the cliff wall of a river bank after cuttage propagation and rooting, the liana plants are connected and fixed on a supporting net through branches and leaves to form a greening net, yellow leaves and dried old leaves are removed in time in the growing process of the liana plants, the consumption of normal stems and leaves and the nutrient content of soil is avoided, the greening net covers the cliff wall of the whole river, and when the liana plants grow to fill the surface of the supporting net, pruning is carried out to ensure air permeability, so that the water body of the river is purified, and the cliff wall of the river bank is greened;

(2) The ivy is perennial evergreen climbing shrub, aerial roots, stem gray brown or black brown, smooth, single leaf alternate, evergreen in four seasons; the scindapsus aureus belongs to large evergreen liana, grows on rocks and trunks of rainforests in a climbing mode, is strong in winding performance, developed in air roots, capable of being planted in a water culture mode, fast in growth and good in greening effect;

(3) the liana grows along the supporting net, the supporting net plays a role in supporting and guiding the growth of stems and leaves for the hydroponic plants, so that the liana is covered on the cliff wall of the whole river bank to form a greening net, and the ecological value, the ornamental value and the aesthetic value of the urban river can be greatly improved;

(4) The supporting net is fixed on the cliff wall of the river bank, so that vine plants can climb conveniently, the base plate is used for supporting and fixing the planting pot, and the vine plants grow after being planted in the planting pot and grow along the supporting net;

(5) The binding belt is used for binding the liana to enable the liana to be covered with the whole supporting net to form a greening net;

(6) The arrangement of the first through holes and the second through holes enables the roots of the lianas to grow downwards under the action of gravity and to go deep into a river channel, and COD, nitrogen and phosphorus in water are degraded by using the principle of ecological engineering aiming at eutrophic water quality, so that the nutrition of the water body is transferred, and the phenomena of fishy smell and eutrophication of the water body caused by the shortage of sealing or self-circulation of the water body are reduced.
