Earth spray-seeding greening base material and slope ecological protection construction method

Abstract

The invention relates to an earth spray-seeding greening base material and a slope ecological protection construction method. The earth spray-seeding greening base material comprises a base layer matrix, an intermediate layer matrix and a surface layer matrix, and is characterized in that the base layer matrix comprises the following raw materials in parts by weight: 380 parts of planting soil, 210 parts of organic fibers, 70 parts of organic matters, 20 parts of a fertilizer, 95 parts of an adhesive, 22 parts of a water-retaining agent and 30 parts of a soil conditioner; the intermediate layer matrix comprises the following raw materials in parts by weight: 450 parts of planting soil, 200 parts of organic fibers, 300 parts of organic matters, 20 parts of a fertilizer, 40 parts of an adhesive, 32 parts of a water-retaining agent, 13 parts of a soil conditioner, 2 parts of a rooting agent, 2 parts of fenaminosulf and plant seeds; the surface layer matrix does not contain plant seeds, and the rest is the same as the intermediate layer matrix. On the premise that the air permeability of the base material is not affected, the bonding effect and the bonding stability are improved, and the occurrence time of soil erosion such as loosening and falling of the base material due to poor bonding effect is prolonged.

Description

technical field [0001] The invention belongs to the field of ecological protection, and in particular relates to a greening base material sprayed with foreign soil and a construction method for slope ecological protection. Background technique [0002] Soil spraying refers to the use of special mechanical equipment to uniformly mix soil, organic matter, plant seeds and various additives together in a certain proportion, and use compressed air or high-pressure water flow as the carrier to spray the mixed material on the ground to be protected. The surface of the slope enables it to quickly establish a stable plant community, so as to achieve the purpose of ecological environment construction and protection of protecting the slope and restoring vegetation. [0003] However, the plant fibers of the existing spray-seeded greening substrates usually use crop straws, which are cut into small sections of 1 to 3 cm and used. Due to their large diameters, although the air permeabilit...

Problems solved by technology

[0003] However, the plant fibers of the existing spray-seeded greening substrates usually use crop straws, which are cut into small sections of 1 to 3 cm and used. Due to their large diameters, although the air permeability is sufficient, the soil erosion is serious after the substrates are sprayed. In 1 to 2 months, the binder will fail and the base material will loosen and fall off, seriously affecting the stability of the base material
