Technical Key Points
1. The base material for spraying is a crucial factor for the success of the spraying process. Peat soil is an excellent material for spraying, which can be mixed with wood fiber (or pulp) in a certain ratio for use. This mixture offers superior adhesion and water retention properties compared to using pure wood fiber alone. It is suitable for spraying on slopes with thin soil layers, extremely barren, or even weathered rock, with an average spraying thickness of about 10 cm.
2. Water-retaining agent and adhesive usage. The water-retaining agent can be adjusted according to the varying climatic conditions and characteristics of different stone quarries; the adhesive quantity depends on the slope of the stone wall, increasing proportionally with the slope's steepness.
3. Anchoring and Mesh Installation. First, securely fasten anchor pins at specific intervals on the stone wall, followed by the mesh installation. The mesh is typically made of galvanized iron wire (also known as wire mesh, chicken wire, or woven wire mesh).
4. Seed Selection: The grass seeds to be sown should be perennial varieties with well-developed root systems, quick to grow into a lawn, drought-resistant, and tolerant of poor soil conditions; if the local winters are cold, consider the varieties' frost resistance as well.
5. Mixed Sowing. Utilize the complementary characteristics of grass seeds, such as deep-rooted and shallow-rooted, legumes and graminoids, local and imported, early and late development, etc., for mixed broadcast sowing.
