Spray-seeding planting method for mountain restoration

Abstract

The invention relates to a spray-seeding planting method for mountain restoration. The method comprises the following steps: S1, after unstable soil and stones are arranged, fixing a wire mesh to a slope surface by using an anchor rod; S2, spraying slurry to a base layer: spraying a first matrix on the slope surface, so that the first matrix fully fills the space under the mesh to form a first matrix layer; S3, performing surface layer spray-seeding: after the first matrix layer is adhered stably, laying a vegetation mesh, performing soil dressing spray-seeding, so that a second matrix with plant seeds fills pores of the vegetation mesh to form a second matrix layer, wherein the vegetation mesh is degradable, and the plant seeds are subjected to pelleting coating treatment; and S4, performing maintenance management: after spray-seeding, covering the surface with a sunshade mesh or non-woven fabric, performing regular watering, fertilization and insect prevention maintenance, and removing the sunshade mesh or non-woven fabric after the seeds germinate. According to the method provided by the invention, the plant seeds are subjected to coating treatment, so that the initial environment of the growth of the plant seeds is purified, the seed germination is promoted, and the germination rate and the seedling rate of the seeds are improved.

Description

technical field [0001] The invention belongs to the technical field of spray sowing, and in particular relates to a spray sowing planting method for mountain restoration. Background technique [0002] Seeding is a new technology suitable for greening of rock-soil slopes with a high degree of weathering and rock-soil slopes. It uses a special jet machine to spray organic substrates such as grass seeds and water-retaining agents onto the slope. The organic substrates are tightly combined with the slope under the action of pressure to form a substrate layer for plant growth and development. For rock-soil slopes and soil-and-rock slopes, the traditional control method generally adopts three-dimensional net grass planting technology. Practice has proved that due to the poor soil conditions of this type of slope, the three-dimensional net grass planting technology still cannot achieve good results, and the soil conditions on the slope surface cannot be changed. The use of foreign...

However, for steep slopes, since the matrix of guest soil spraying is still mainly planting soil, lack of fixation, the anti-erosion effect is very limited, and it is easy to be lost under the erosion of rainwater or runoff
