Embodiment 1

[0018] Embodiment 1, a vegetation concrete, including base concrete at the bottom and surface concrete at the top, the base concrete is sprayed with vegetation concrete matrix material, and the surface concrete is sprayed with vegetation concrete matrix material mixed with grass seeds.

[0019] The manufacturing method is:

[0020] 1. Raw material pretreatment: Air-dry and crush the raw planting soil (sandy loam, soil pH value 7.84, hydrolyzable nitrogen content 115.62mg / kg, available phosphorus 124.37mg / kg) and sieve, the maximum particle size shall not exceed 8mm, and the water content shall not More than 20%; organic matter (distiller's grains, purchased from China Resources Snow Brewery (Heilongjiang) Co., Ltd.) was selected for crushing.

[0021] 2. Planting soil (sandy loam), cement (P.O.325 ordinary Portland cement, purchased from Yatai Group Harbin Cement Co., Ltd.), organic matter (distiller's grains), concrete greening additive (LY produced by Green Field Environment...

Abstract

The invention relates to vegetation concrete, and belongs to the field of ecological restoration engineering. The vegetation concrete comprises base concrete located at the bottom and surface concrete located at the top, the base concrete is sprayed by vegetation concrete matrix materials, the surface concrete is sprayed by the vegetation concrete matrix material mixed with grass seeds, and the vegetation concrete matrix materials comprise, by mass, 75-85% of raw planting soil, 6-12% of cement, 2-5% of organic matters, 2-5% of concrete greening additives and 2-5% of arbuscular mycorrhizal fungi inoculant which are compatible. The problems that vegetation growth is stressed by matrix materials, and vegetation is easy to degrade in a maintenance process on existing vegetation concrete technical conditions are solved, and pollutant intercepting capacity when a vegetation concrete technology is applied to a buffer zone is enhanced.

Description

technical field [0001] The invention relates to a novel vegetation concrete, belongs to the field of ecological restoration engineering, and provides a preparation method of the vegetation concrete. Background technique [0002] Vegetation concrete technology is a new technology for protecting and greening rock slopes by using specific concrete formula and seed formula. For example Chinese patent CN201010553970.6 discloses "concrete for greening vegetation and construction method thereof", the concrete includes base concrete with a thickness of less than 5cm at the bottom and grass surface concrete with a thickness of 5cm to 10cm at the top. The ingredients are: fly ash, overburned magnesia, ammonium dihydrogen phosphate, sodium bicarbonate, sand, plant fiber and coagulation-adjusting materials; the ingredients of grass surface concrete are: fly ash, overburned magnesia, Hydrogen amine, sodium bicarbonate, raw planting soil and humus; Another example is the "cement slope ve...
