Problems solved by technology

Since soil is a non-renewable resource, long-term use will reduce its reserves, and the cost of use will become higher and higher
Moreover, taking soil will cause secondary disasters to take land and destroy the ecological environment of the taken land
In addition, because the soil is heavy, less cohesive, and prone to landslides, it is difficult to apply it on rocky slopes above 60 degrees. Therefore, how to reduce the amount of soil or use no soil in the spraying technology, and at the same time achieve spraying on slopes above 60 degrees Application is a technical problem to be solved

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soilless spraying substrate for high and steep rocky slopes and an application method thereof. Background technique [0002] At present, aggregate spraying, guest soil spraying, and hydraulic spraying are widely used. Guest soil spraying is suitable for grass-roots spraying and is more efficient. The cost of high-order aggregate spraying is slightly higher. Sowing is easy to cause fertilizer pollution and loss of silt and clay, and will be gradually eliminated. Soil spraying, hydraulic spraying and organic matter spraying technologies are only suitable for slopes with a slope ratio of less than 1:1, and only aggregate spraying is suitable for steep slopes, but the slope ratio is less than 1:0.5, but its high cost limits its use. App promotion. [0003] Soil material and formulation are at the heart of seeding technology. Since soil is a non-renewable resource, long-...
