Beneficial effects of the present invention: the accumulation of salt in the surface soil phenomenon in salt-soda soil casting counterfort virescence is reduced, solves salt-soda soil shield
The problem that slope vegetation is single and survival rate is low, specific as follows:
(1), the mixed concrete revetment of greening is divided into base and surface layer by the present invention, is first poured base and is then poured again in base
Surface layer is infused, two layers of porosity is controlled, so that the porosity of base is greater than the porosity on surface layer, compare one-course concrete, can
Porosity lower layer is caused to be less than surface layer, to which there is a situation where gaps to block to avoid because slurry flows downward；In addition, of the invention
The pH value of the mixed concrete mortar of greening be down to 8 or so；
(2), on the one hand the base of greening concrete protective slope of the present invention plays the role of reinforcing slope surface, on the other hand, hole
Rate, which is greater than surface layer, can prevent green concrete pore plugging, furthermore it is also possible to effectively obstruct the capillarity in salt-soda soil, play
It is certain every salt effect so that plant strain growth is not influenced by saline and alkaline, improve vitality；In the preparation process of substrate concrete
In, it is first made using plant fiber, emulsified wax and calcined diatomite and inhales salt particle, calcined diatom soil pores is expanded
Greatly, plant fiber is adsorbed on its surface by emulsified wax, and emulsified wax embeds diatomite, and plant fiber protects the hole of diatomite
Structure and pore channel can be absorbed or be permeated by plant fiber when the salinity in soil as moisture rises to base
Into the pore structure of diatomite, it is difficult to shake off again into the salinity for inhaling salt particle, thus the suction salt in substrate concrete
Grain can further be assisted every salt；
(3), in the preparation process of Surface layer's concrete of the present invention, silica solution and nano-titanium dioxide are weighed according to the proportion, are mixed
It closes uniformly, heating load addition is attapulgite modified, and drying obtains hybrid solid, hybrid solid viscosity with higher and water suction
Property, moisture can be effectively lockked, provides good environment of taking root for Orychophragmus violaceus root system, humus and nutrient solution promote Orychophragmus violaceus root
System's growth is even more that the flowers are in blossom in flakes in the time in early spring in addition, still greenery are verdant and thick in winter for Orychophragmus violaceus, relatively existing
Green concrete, improve aesthetic measure；
(4), the present invention sows grass seeds by duster orychophiagmus violaceus seed to the green concrete surface layer poured in slope surface, and Orychophragmus violaceus region of sowing grass seeds by duster is
1/2 ~ 3/4 slope surface upward from bottom of slope sows grass seeds by duster Radix Glycyrrhizae or bluish dogbane seed to remaining slope surface, and trickle irrigation is arranged in top of the slope
Pipe, it is in this manner, i.e., acidproof drought-enduring since its is adaptable close to the ecological region planting Radix Glycyrrhizae of top of the slope or bluish dogbane,
Not tight to soil requirement, especially growth water requirement very little, cooperation drip irrigation pipe can make moisture moisten downwards for a long time from top of the slope
It is wet, Soil Slope humidity is kept, while can mention to avoid the cost caused by entire slope surface laying drip irrigation pipe or spray equipment
It is high and process is tedious；
