Problems solved by technology

At present, traditional alien soil matrix materials are mostly local materials, which have the characteristics of water retention and high water absorption, but they do not consider the soil properties and geological conditions of different environments. Optimum growth
The prior art (CN104909897A) discloses a PAM-conditioned powerful ecological green-covered soil spray, which is characterized in that it is prepared from the following raw materials in parts by weight: planting soil 80-85, conditioning agent 0.2-0.6, PAM water-retaining agent 1-3, N, P, K compound fertilizer 1-2, binder 2-6, plant fiber 2-4, water 5-7, the PAM conditioning strong ecological green-covered guest soil spraying, the guest soil spraying The porosity is moderate and the water retention performance is good, but the plant fiber length is short, and the stability and firmness of the guest soil layer formed are not good. In order to solve the deficiencies of the prior art, the invention provides an ecological guest soil for slope greening The spray-seeding composite material has good interweaving performance, strong soil coverage stability, high organic matter content, high environmental safety, and at the same time makes the soil soft and non-caking, which is of great significance for promoting the development of my country's spray-seeding greening industry

Abstract

The invention discloses a compound organic fiber, an ecotype alien soil spray-seeding composite material and a preparation method thereof.The compound organic fiber is prepared from, by weight, 75-80% of coconut cellosilk, 2-5% of coconut residues and 15-20% of thoroughly-decomposed wheat straw.The ecotype alien soil spray-seeding composite material is mainly prepared from, by weight, 100 parts of the compound organic fiber, 0.004-0.006 part of surfactant, 0-0.002 part of a plant growing regulating agent and 0-5 parts of compound fertilizer.The compound organic fiber in the ecotype alien soil spray-seeding composite material has good interweaving performance and water retaining performance, the ecotype alien soil spray-seeding composite material can be mixed with peat soil, grass seeds and the like to form uniform and stable paste, the paste is attached to a construction face so that a bird-nest-shaped alien soil covering layer can be formed, and stability is improved when an alien soil layer is attached to a slope.

Description

technical field [0001] The invention belongs to the field of ecological and environmental protection science and technology, and specifically relates to a composite organic fiber, and also relates to an ecological type guest soil spraying composite material and a preparation method thereof. Background technique [0002] In recent years, with the accelerated pace of urbanization in my country, the rapid development of infrastructure, and the continuous expansion of various construction projects, high filling and deep excavation in the construction of railways, highways, mines and other projects directly destroy the surface, change the original landform, and produce Large areas of exposed high and steep slopes have resulted in serious soil erosion around the project area, reduced biodiversity, and aggravated slope instability in geologically fragile areas, which has aggravated the deterioration of the local ecological environment. In order to avoid this situation, it is necessa...
