Embodiment

[0050] A method for preparing soil-rock mixed slope spraying matrix, adding loamy soil, clay, reed fiber, bio-organic fertilizer, water-retaining agent, and binder into a mixer, stirring and mixing to obtain a soil-rock mixed slope spraying Matrix, the proportion of each component of the matrix is ​​as follows:

[0051] Table 1 Distribution ratio of each matrix component

[0052]

[0053] Among them, the quality of binder and water retaining agent can be ignored when calculating soil bulk density;

[0054] Using 10 substrates with different formulations in Table 1 to mix four kinds of plants such as Tall Fescue, Saltawan, Elymus, and Echinacea, the results of the germination and emergence rate test are as follows:

[0055] Table 2 Growth table of main test plants

[0056]

[0057] In order to compare the anti-scouring ability of reed fiber sprayed on the soil-rock mixed slope, the formula combination and comparative example with good seedling effect in the embodiment o...

Abstract

The invention discloses a spray-seeding medium for soil-rock mixed side slopes and a preparation method of the spray-seeding medium. The spray-seeding medium for the soil-rock mixed side slopes is mainly prepared from, by mass, 23-40% of clay, 50-75% of loamy soil and 0.6-12% of reed fibers, wherein the length of the reed fibers ranges from 20mm to 120mm. The spray-seeding medium for the soil-rockmixed side slopes are mainly prepared from the clay, the loamy soil and the reed fibers, which are compounded according to specific proportions; the structural stability, pulling force and adhesive force of the medium are enhanced through the reed fibers, and the degraded reed fibers serving as bio-organic fertilizer provide nutrients for plant growth; the problems caused after spray seeding of conventional media, such as poor structure, few granular structures and nutrient shortage of the soil, as well as the problem of unstability caused by efficacy loss of binders, are solved; resource utilization of reeds can be realized.

Description

technical field [0001] The invention relates to the field of water and soil protection, in particular to a soil-rock mixed slope spraying substrate and a preparation method thereof. Background technique [0002] Soil spraying is to fully mix loamy soil, plant fiber, plant seeds, fertilizer, water-retaining agent, binder, peat soil, etc., and then spray it evenly to the engineering slope to be protected according to the designed thickness through high-pressure equipment and jetting On the one hand, through reasonable maintenance and management of plant growth, the purpose of rapid greening and stabilization of barren slopes can be achieved. 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...
