Embodiment 1

[0025] Embodiment 1. Baotou Steel (Group) Company Tailings Dam Slope Vegetation Restoration Project:

[0026] The slope of this project is mixed with sandy soil and tailings powder, with poor soil quality, harsh surrounding climate conditions, drought, little rain, and strong wind. To this end, we adopt the following methods for spraying greening.

[0027] (1) Slope surface treatment: Manually remove dangerous stones, loose stones and other weeds and waste on the surface to ensure that the slope is smooth.

[0028] (2) Slope shaping: In areas with large slopes, use mechanical or manual slope cutting to make the slope suitable for spraying operations and plant growth.

[0029] (3) Lay the metal mesh: Lay the mesh from bottom to top, the overlapping length between the metal meshes should not be less than 10 cm, and use anchors to fix the metal mesh.

[0030] (4) Spraying substrate and seeds: Add the prepared water, plant growth substrate and seeds into the hopper of the sprayi...

Embodiment 2

[0037] The proportioning of medium material in adjusting embodiment one is as follows:

[0038] Clay soil 33%; perlite 32%; montmorillonite 20%; rice husk (decomposed) 35%; stabilizer 1.2%; slow-release fertilizer 4%; pellet agent 0.6%; clear water 38%;

[0039] Among them, the proportion of plant seeds is: black locust, 7g; torch, 5g; Caragana, 4g; , 8g.

[0040] (1) Slope surface treatment: Manually remove dangerous stones, loose stones and other weeds and waste on the surface to ensure that the slope is smooth.

[0041] (2) Slope shaping: In areas with large slopes, use mechanical or manual slope cutting to make the slope suitable for spraying operations and plant growth.

[0042](3) Lay the metal mesh: Lay the mesh from bottom to top, the overlapping length between the metal meshes should not be less than 10 cm, and use anchors to fix the metal mesh.

[0043] (4) Spraying substrate and seeds: Add the prepared water, plant growth substrate and seeds into the hopper of th...

Abstract

The invention discloses a plant growth matrix with high water retention for spray seeding revegetation and a preparation method thereof. The plant growth matrix comprises an upper layer and a lower layer, wherein the lower layer is a plant growth matrix layer, and the upper layer is an organic matter covering layer covered on the plant growth matrix layer. According to the invention, perlite and montmorillonite with high hydroscopicity are applied to modification of the matrix for spray seeding revegetation, an organic matter is used to cover the surface of the plant growth matrix, a preparation process for the matrix is optimized, and thus, the disadvantage that moisture in a common matrix easily volatilizes is improved; the matrix for spray seeding revegetation has good adhesion, can be firmly attached on the surface of a bare rock side slope, well absorbs and maintains moisture, uninterruptedly provides moisture and nutrient elements needed by plant growth, guarantees revegetation of the side slope and has the advantages of low cost and easiness in manufacturing. Through implementation of a technical scheme in the invention, it is overcome that vegetation easily dies from drought after spray seeding of nonlocal soil on a side slope in an arid rainless region in China.

Description

technical field [0001] The invention relates to a plant growth substrate and a water retention method thereof, in particular to a plant growth substrate with high water retention for spraying greening and its preparation and water retention method, which can be widely used in mine vegetation restoration, land greening, municipal engineering, roads, etc. Bridge engineering, agricultural planting and other technical fields. Background technique [0002] Vegetation slope protection is to protect the slope with living plants to reduce the instability and erosion damage of the slope. The earliest vegetation slope protection method was used for bank protection of river embankments and treatment of barren hills. In the 1930s, hydraulic spraying planting technology was studied and used in agriculture and road slope engineering. Japan's slope greening started earlier, and its leading idea was "construction and greening at the same time". In the 1970s and 1980s, Japan successively de...
