Technical Key Points
1. The base material for spraying is a crucial factor for the success of the spraying process. Sphagnum peat is an excellent material for spraying, which can be mixed with wood fibers (or pulp) in a specific ratio for use. This mixture offers superior adhesion and water retention compared to using pure wood fibers alone. It is suitable for spraying on slopes with thin soil layers, extreme barrenness, or even weathered rock, with an average spraying thickness of about 10cm.
2. Water-retaining agent and adhesive usage. The amount of water-retaining agent can be adjusted according to the local climate conditions and the specific characteristics of the stone quarry; the adhesive quantity is determined by the slope of the stone wall, with a direct proportionality to the slope's steepness.
3. Installation: First, anchor pins are fixed at certain intervals on the stone wall, followed by the hanging of the mesh. The mesh is typically made of galvanized iron wire mesh (also known as welded wire mesh, grid mesh, or machine-woven mesh).
4. Seed Selection: The grass seeds used for sowing should be perennial varieties with well-developed root systems, quick to establish into a lawn, drought-resistant, and tolerant of poor soil conditions; if the local winter is cold, the frost resistance of the variety should also be considered.
5. Mixed Sowing. Utilize the complementary characteristics of grass seeds, such as deep and shallow root systems, legumes and grasses, foreign and local varieties, early and late development, etc., for mixed broadcast sowing.
