Ecological protection greening substrate for rock slope

Abstract

The invention discloses a rock slope ecological protection afforestation substrate. The substrate is prepared by evenly mixing a mixture of mixed and fermented straw, cattle manure, edible fungus refuse (the waste after the edible fungus production), sludge and organic matter fibers, compound fertilizer, a soil moisture holding agent, a binding agent, attapulgite powder and a pH regulator. The rock slope ecological protection afforestation substrate is used to carry out the spray seeding and greening on the exposed rock slope, the discarded mine and the mountain gap, and can maximally restore the vegetation ecology in a shorter period, thereby reaching the aims of afforestation and slope protection. The substrate can supply a reasonable physical structure and nutrient contents needed by the growth of the vegetation, and ensure the sufficient cohesion force between the substrate mixture on the slope surface and the rock slope so as to ensure that the vegetation on the slope surface can take root and grow well on the rock slope. The substrate can ensure the stability of the substrate mixture on the slope surface so as to resist the rain erosion. The substrate can rapidly seal the slope surface and prevent the slope surface from flaking off due to efflorescence together with the vegetation.

Description

Technical field: [0001] The invention belongs to the technical field of ecological restoration of environmental protection, and particularly relates to an ecological protection matrix that can be applied to high and steep rocky slopes in arid and semi-arid areas, seasonal droughts, and areas with concentrated and large rainfall. Background technique: [0002] The research on the ecological protection of rocky slopes started earlier in foreign countries. Japan developed the Fiber-soil Greening Method in 1973, marking the beginning of the rock greening project. This is also the earliest thick soil greening method developed in Japan Layer-based spraying method, that is, by spraying on the slope a thicker layer of base material required for plant growth with a structure similar to natural soil and capable of storing water and nutrients. [0003] The general method adopted by European and American countries in the ecological management of slopes is to cut down the slope first, th...

Problems solved by technology

[0008] (2) The formula of the base material is the same, which affects the effect of ecological slope protection and engineering acceptance

[0009] The currently implemented substrate formulations cannot adapt to the requirements of ecological environments such as different regions, geological engineering conditions, soil types, and vegetation adaptability, especially the selection of plant species and the cultivation of dominant communities have not been able to consider climate conditions, soil types, and geology. Conditions, slope, aspect (shady or sunny) and other ecological elements often fail to achieve the desired ideal effect

[0010] (3) Vegetation engineering technology cannot adapt to the needs of different geology, rock and soil, slope and slope shape

[0011] During the implementation process of the construction unit, the construction technology is single, and it cannot adapt to local conditions, adapt to different geology, rock and soil, slope and slope shape requirements, and the construction quality is unstable, which also affects the effect of slope greening to a certain extent.
