Problems solved by technology

[0004] At present, there is a phenomenon of lack of nutrients in the artificial soil formed by spraying at the later stage, which leads to the reduction of vegetation coverage; according to the actual status of slope protection projects, the adhesive varieties sold on the market at this stage are mixed with good and inferior, and the action time of the adhesive is too short As a result, the water and soil conservation effect of alien soil spraying is weakened, the stability of the slope is reduced, and infinite safety hazards are brought

Abstract

The invention provides a spray seeding matrix and a preparation method thereof. In the spray seeding matrix provided by the invention, the soil, straw, adhesive and fertilizer are used as main raw materials which are doped with some of construction waste; and by adopting a combination of special dosage ratio, the obtained spray seeding matrix has high strength, the stability can be maintained for a long time, the fertilizer efficiency lasts long, the cost is low, and the greening effect can be effectively improved. By adding the spray seeding matrix into the construction waste, the slope stability can be effectively improved, the greening quality is increased, and the investment cost is lowered. The spray seeding matrix provided by the invention improves the problems such as relatively bad structure, relatively few granular structures and nutrient lack of the soil formed after the spray seeding of the traditional matrix and the problem of instability caused by adhesive failure. The indexes of the spray seeding matrix can reach the traditional matrix standard, wherein the early-stage growth condition of the plant, the plant biomass, the soil fertility, the erosion resistance and the like are all greatly improved. The preparation method of the spray seeding matrix provided by the invention is simple in technology, low in cost and suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of water and soil protection, in particular to a spraying substrate and a preparation method thereof. Background technique [0002] Soil spraying is to fully mix plant seeds, fertilizers, water-retaining agents, binders, peat soil and other mixtures, and spray them evenly on the slope of the project to be protected according to the designed thickness through high-pressure equipment and jetting machines. Plant growth achieves the purpose of fast greening and stabilizing barren slopes. The spraying matrix itself has a certain stability, and at the same time can supply nutrients and water to the vegetation. It restores the ecosystem destroyed by the construction and development of the project, and cultivates a stable slope and vegetation that is harmonious with the surrounding environment, which can be done as quickly and correctly as possible It can be restored to its original green state. The foreign soil s...
