Problems solved by technology

[0003] However, traditional vegetation substrates cannot meet the needs of long-term growth of plants in vegetation concrete, and the main problems are as follows: ①Poor erosion resistance
Vegetation Concrete Surface Vegetation Substrate is very vulnerable to rain erosion before the plants form effective protection on the slope, causing water and soil, nutrient loss, and even the loss of seeds with water and soil, reducing the germination rate, which is not conducive to plant growth
② High salinity
Due to reasons such as saline-alkali and insufficient water retention, the internal pore soil and surface soil of porous vegetation concrete are prone to compaction, and then form splash erosion and surface erosion, resulting in soil erosion

Abstract

The invention discloses an alkalinity-substracting planting material applicable for vegetation-growing concrete and preparation method thereof. The alkalinity-substracting planting material comprises an interlayer and a top soil layer, therein the interlayer is prepared from the following components by mass: 30%-40% parts of soil, 45%-55% parts of humus soil, 0.85%-1.65% parts of compound water-preservation agent, 3.0%-5.0% parts of coal ash, 3.0%-5.0% parts of gypsum, 0.5%-1.0% part of controlled release fertilizer, 0.5%-1.0% part of mixed cultured bacteria and other enzyme materials. The top soil layer is prepared from the following components by mass: 40%-50% parts of soil, 30%-40% parts of humus soil, 0.85%-1.65% parts of compound water-preservation agent, 3.0%-5.0% parts of coal ash, 3.0%-5.0% parts of gypsum, 1.0%-2.5% parts of adhesive, 2.0%-3.0% parts of plant fiber, 0.5%-1.0% part of compound fertilizer. The planting material has the advantages of alkalinity substraction and anti-erosion.

Description

technical field [0001] The invention relates to the technical field of porous soil and surface soil improvement of vegetation concrete, in particular to an alkali-reducing plant growth base material suitable for vegetation concrete and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and the acceleration of infrastructure construction in various places, the construction of civil engineering, transportation, water conservancy and hydropower, mining and other projects requires the excavation of a large number of slopes. Water and soil erosion, ecological imbalance and other problems, landslides, mudslides and other geological disasters occur from time to time. Slope protection has become the main engineering technical means to solve the above problems. In traditional slope protection, hard slopes such as masonry slope protection are usually used. Although it has the advantages of high strength and good durability, it...
