Marine organism spray-seeding substrate for slope protection and implementation process of marine organism spray-seeding substrate

Abstract

The invention discloses a marine organism spray-seeding matrix for slope protection and an implementation process thereof. The marine organism spray-seeding matrix comprises the following components in parts by weight: 20-25 parts of soil, 20-25 parts of shell powder, 5-10 parts of seaweed-based biochar, 10-15 parts of hermetia illucens sand, 10-15 parts of expanded fibers, 2-6 parts of a soil conditioner, 8-10 parts of a slow-release compound fertilizer and 0.05-0.7 part of plant seeds. Most raw materials of the matrix are from agricultural production solid wastes and domestic solid wastes, the solid wastes are recycled through fine processing of the wastes, and the shell powder and the hermetia illucens sand contain various probiotics, so that the construction of a soil microbial ecological system can be accelerated.

Description

technical field [0001] The invention belongs to the technical field of slope ecological protection, and in particular relates to a marine biological spraying substrate for slope protection and an implementation process thereof. Background technique [0002] At present, with the rapid development of my country's economy and society, people's requirements for the living environment are getting higher and higher. Especially after the slogan that green water and green mountains are golden mountains and silver mountains was put forward, a large number of bare mountain and mine management projects have emerged in various places. Among them, ecological Seeding is the most commonly used and most adaptable technique. [0003] At present, there are mainly two kinds of substrates used in ecological spraying, one is vegetation concrete technology, and the other is CS mixed fiber technology with high-order aggregates as binder. The former adds cement and bacterial agents to the soil, and...

AI Technical Summary

Problems solved by technology

The former adds cement and bacterial agents to the soil, and uses cement as the binder to realize greening. However, the vegetation concrete technology using ordinary Portland cement as the gel material has no concrete alkali reduction technology, which leads to long-term salinization of the matrix. The soil structure is poor, and the vegetation is seriously degraded; the latter uses polyacrylamide, emulsified asphalt and other materials as adhesives, but these polymer materials are soluble in water, and will be washed away by rain after spraying, resulting in the loss of cohesion of the matrix; Such polymer materials are not environmentally friendly and cause secondary pollution

[0004] On the other hand, with global climate change and frequent occurrence of extreme weather, the existing soil spraying technology can no longer adapt to the current climate and meteorological conditions, and the slope collapses and the vegetation seriously degrades under the occurrence of extreme precipitation and extreme temperature Case
