compared with a control group, the germination rate of the seeds of the sample land paved with the ecological vegetation concrete base material in the embodiment 1 is obviously improved, and the average germination rate is improved by 36% after 15 days; the compressive strength is also obviously improved, and the silica fume and the short fiber are added to obviously enhance the slope soil, effectively prevent the vegetation concrete from cracking and play a role in resisting corrosion; the added bacillus subtilis, bacillus mucilaginosus, bacillus amyloliquefaciens, potassium fulvate serving as a mineral source and biochar particles can improve the soil habitat for a long time, greatly improve the soil fertilizer efficiency conversion, promote the plant growth and improve the vegetation coverage rate by 14% in 180 days.
Comparative example
To further verify the technical effect of the concrete substrate described in the present application, the following comparative examples were set up for comparative experiments.
The vegetation concrete base material in the comparative example has the same raw material formulation as in example 1 except that no micro silicon powder is added, and comprises: 120kg of planting soil, wherein the grain diameter of the planting soil is smaller than 1cm, and the water content is 20%; 26kg of cement; 0.12kg of potassium fulvate as a mineral source; 40kg of biomass scraps; 1.5kg of short fibers; 6kg of biochar particles; 9g of composite microbial inoculum; organic fertilizer, 7kg; 2kg of long-acting slow-release compound fertilizer; the method comprises the steps of carrying out a first treatment on the surface of the Plant seeds 0.035kg. The preparation method of the vegetation concrete substrate is the same as in example 1, except that no silica fume is added in step (2). The vegetation concrete base material prepared by the comparative example is used for a side slope in an experimental example, and the compressive strength of the base material detected on 180 th day after laying is 0.60MPa, which is lower than that of the ecological vegetation concrete base material in the application example 1.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the protection scope of the present invention is subject to the claims.
