Erosion resistant matrix suitable for spray seeding for greening

Abstract

The invention relates to an erosion resistant matrix suitable for spraying, wherein the matrix is prepared by effectively mixing components A and B under certain conditions, and the thickness is 1-3cm. The component A is water, and the component B is composed of high liquid limit soil, peanut shell, adhesive, water-retaining agent and conditioning agent. A mass ratio of the component A to the component B is 1:3, and the component B comprises, by weight: 50-60% of high liquid limit soil, 25-35% of peanut shell, 10-15% of adhesive, 0.2-0.4% of water-retaining agent, and 1-3% of conditioning agent. The matrix has advantages of strong structural stability, high erosion resistant degree and good insulation effect, can effectively intercept nutrient and moisture in a plantation layer, can furthest participate in external water-air cycle, greatly raises germination capacity and growth speed of seeds. The matrix has advantages of rich raw material, simple process, low price, convenient use and non pollution, and has substantial social and environment benefits.

Description

technical field [0001] The invention relates to an erosion-resistant matrix suitable for spray-seeding greening, which can be widely used in fields such as water and soil conservation, ore regreening, land greening, traffic engineering, municipal construction, and the like to prevent slopes from being eroded. Background technique [0002] In the prior art, CN1292988A provides a rock slope vegetation slope protection planting base, the components of which are composed of greening substrate 86-93, mixed grass species 1.5-4.0, stabilizer 5.0-10, and aggregate agent 0.4-1.0. [0003] CN1121059A provides a kind of slope protection vegetation concrete, its cement, stone, sand, ceramsite, water, the consumption between them is 1:3.4~4.0:0.46~0.6:0.3~0.47:0.40~0.50, wherein cement is 425#, Ceramsite is ceramsite sprayed with compound fertilizer in advance. [0004] CN102675000A provides a method for preparing soil medium suitable for plant growth in industrial alkaline tailings dam...

AI Technical Summary

Problems solved by technology

Due to the low cohesive force of the mud itself, the mud jet method cannot resist the erosion of rainwater, and it is easy to cause landslides on the slope.

For the cement-soil spraying method, because the cement is easy to bond with the soil and form plates, it cannot form the optimal aggregate structure required for plant growth

However, another slope protection technology is to punch and weave fences on the slope, which is labor-intensive and time-consuming, and it is difficult to be popularized and utilized.
