Spray seeding matrix for regreening of bare side slope adapted to soil in arid and semi-arid zones and preparation method of spray seeding matrix

Abstract

The invention relates to the technical field of environment protection and greening of side slopes, and provides a spray seedling matrix for regreening of bare side slope adapted to soil in arid and semi-arid zones and a preparation method of the spray seeding matrix. The spray seedling matrix provided by the invention is prepared from the following raw materials in parts by weight: 25 to 40 parts of composted organic wastes, 30 to 40 parts of side slope loess, 5 to 15 parts of kaolin, 0.5-0.8 part of potassium fulvate, 5 to 15 parts of bentonite clay, 3 to 4 parts of flour sticky glue and 5 to 10 parts of plant fibers. According to the spray seedling matrix, intensive aboveground parts and developed root systems of plants can be quickly formed on the long-term arid and bare side slope, regreening of the side slope can be effectively carried out, the soil is consolidated, and surface runoff and soil washing can be prevented and controlled. The preparation method provided by the invention comprises the steps of mixing the composted organic wastes, the side slope loess, the kaolin, the potassium fulvate and the bentonite clay and pulverizing into particles; then mixing the particles with the plant fibers to obtain a mixture; successively, adding water and stirring the mixture to form a viscous state; then mixing the viscous product with the flour sticky glue. The preparation method has the advantages of simple technology, strong operability and benefit to industrial production.

Description

technical field [0001] The invention relates to the technical field of environmental protection slope greening, in particular to a spraying substrate suitable for regreening soil exposed slopes in arid and semi-arid areas and a preparation method. Background technique [0002] The soil slope soil in arid and semi-arid areas has the characteristics of lack of humus, loose soil and easy collapse, weak erosion resistance, sparse vegetation, low nutrient content, slow soil-forming process, and extremely poor soil fertility and water retention. Due to the special physical and mechanical properties of the soil in the region and the complex and changeable climatic and environmental conditions in the arid and semi-arid regions, these slopes have experienced various disasters such as gullies and erosion, which have caused serious soil erosion and destroyed the ecological landscape. Restoration of original ecological vegetation on slopes has always been a research topic at home and ab...

[0002] The soil slope soil in arid and semi-arid areas has the characteristics of lack of humus, loose soil and easy collapse, weak erosion resistance, sparse vegetation, low nutrient content, slow soil-forming process, and extremely poor soil fertility and water retention. Due to the special physical and mechanical properties of the soil in the region and the complex and changeable climatic and environmental conditions in the arid and semi-arid regions, these slopes have experienced various disasters such as gullies and erosion, which have caused serious soil erosion and destroyed the ecological landscape. Restoration of original ecological vegetation on slopes has always been a subject of research at home and abroad

[0003] At present, although there are many patented technologies for regreening bare slopes in China, the ecological restoration technologies for the special environmental conditions in arid and semi-arid areas are not mature enough, and the pertinence is not strong. The effect of regreening slopes is poor and the cost is high.
