Problems solved by technology

[0005] The purpose of the present invention is to overcome the soil medium and plant seeds in the prior art that are difficult to cover and fix on the bare rock, and cannot resist the soil caused by factors such as rain erosion. Due to the shortcomings of medium loss and vegetation community degradation and death, a barren mountain rock greening technology is proposed

Embodiment Construction

[0043] 1. Prepare materials

[0044] A material preparation: soil base (containing organic humus, slow-release fertilizer, appropriate amount of water-absorbing and water-retaining agent, bonding reinforcement materials such as plant fibers, etc.) add appropriate amount of water and stir evenly;

[0045] Preparation of material B: Add appropriate amount of green grass seeds or seeds of other plants to material A and mix well;

[0046] C material preparation: the specially synthesized foaming material is moved into two special storage tanks of the polyurethane high-pressure foaming machine;

[0047] 2. Pretreatment of bare rock surface before spraying

[0048] Specifically, use a high-pressure water gun to rinse to remove floating dust and debris on the surface;

[0049] 3. The first spraying

[0050] A soil sprayer is used for material A, and a polyurethane high-pressure foaming machine is used for material C to select the appropriate output ratio and spray to the bare rock i...

Abstract

The invention belongs to the technical field of barren hill greening and ecological protection, and is a rock vegetation planting technology for barren hill greening and preventing water and soil loss. The core of the invention is the preparation of a barren hill rock greening material and its construction technology. The barren mountain rock greening material is a liquid-solid mixture at the initial stage of preparation, including adhesive, organic soil, foaming material, plant seeds and the like. Sprayed on barren mountain rocks or the outer walls of buildings, it can naturally foam at room temperature, and finally form an adhesive layer bonded to the rock, an organic soil layer, a porous foam skeleton and a plant community layer that fix the organic soil layer and plant seeds. This kind of material is non-polluting and can complete natural degradation within a certain period of time. The advantages of the present invention are: this barren mountain rock greening technology can realize the successful planting by spraying once, the construction process is simple, and there is no need for artificial post-maintenance. Moreover, the material is environmentally friendly, and it is firmly bonded to the surface of rocks or buildings, which can resist the impact of rainwater, retain water, fertilizer, and have strong air permeability.

Description

technical field [0001] The invention belongs to the technical field of barren hill greening and ecological protection based on multidisciplinary theories such as material science, soil science, botany, and ecology, and relates to a solid-liquid mixed material for barren hill greening, which is suitable for barren hill greening, growing grass on stones, preventing water and soil Lost barren mountain rock vegetation planting technology. This kind of ecological material has good water retention, fertilizer retention and air permeability, is suitable for plant growth, and has a certain bond strength, can resist harsh environments, firmly adhere to the rock surface, and form plant communities on the rock surface, which is environmentally friendly. Non-polluting and degradable. Background technique: [0002] At present, there are two kinds of vegetation establishment modes in barren hills in foreign countries: including the high maintenance type represented by the United States ...
