Soilless spray-seeding matrix for high and steep rock slope and application method of soilless spray-seeding matrix
The invention provides a soilless spray seeding matrix for a high and steep rock slope. The soilless spray seeding matrix is prepared from the following raw materials in parts by mass: 45 to 55 percent of iron tailings, 35 to 45 percent of dried sludge, 6 to 8 percent of poplar fiber, 1 to 3 percent of organic fertilizer, 0.2 to 0.5 percent of polyacrylamide and 0.5 to 0.8 percent of vinyl acetate-ethylene copolymer emulsion. According to the soilless spray-seeding substrate, iron tailings and sludge serve as main raw materials, soil replacement is not needed, secondary damage to a soil source land caused by secondary soil replacement is avoided, the substrate materials can form an aggregate structure, and the substrate is loose, breathable, high in adhesive force, capable of meeting the spray-seeding requirement of a high and steep slope with the gradient larger than 60 degrees, good in water retention property and high in nutrient content, and has a good application prospect. Nutrients can be stably provided for plants for a long time, the survival rate of the plants is high, and the maintenance cost is low.
本发明提供了一种高陡岩质边坡无土喷播基质，由以下质量份数的原料组成：铁尾矿45~55%、干化污泥35%~45%、杨木纤维6%~8%、有机肥1%~3%、聚丙烯酰胺0.2%~0.5%、醋酸乙烯－乙烯共聚乳液0.5%~0.8%。本发明无土喷播基质以铁尾矿和污泥为主要原料，无需客土，避免了二次客土对土源地造成的二次破坏，且基质物料能够形成团粒化结构，疏松、透气，附着力强，能够满足坡度大于60°的高陡边坡喷播要求，基质保水性好，养分高，可长效且稳定的为植物提供养分，植物的成活率高，且养护成本低。
