Grass fiber spraying seeding substrate for sandy soil and use method thereof

Abstract

The invention discloses a grass fiber spraying seeding substrate for sandy oil. The grass fiber spraying seeding substrate includes, by volume, 20-40 parts of garden soil, 20-40 parts of sandy soil, 0.5-2 parts of slow-release fertilizers, 0.5-5 parts of fast-release fertilizers, 5-10 parts of chicken manure, 5-10 parts of grass fibers, 1-3 parts of binders, and 2-6 parts of water-retaining agents. The invention also discloses a use method of the spraying seeding substrate. The garden soil, the sandy soil, the chicken manure, and the grass fibers are main raw materials, and are combined according to a specific use proportion; the grass fibers are added in the spraying seeding substrate and are excellent in water-retaining performance, waste is turned into useful materials to be recycled, the engineering cost is greatly reduced, and the benefits are increased; the slow-release fertilizers, the fast-release fertilizers and the chicken manure can enrich nutriments of the substrate; and the grass fiber spraying seeding substrate is simple in preparation method is high in operability of construction, and is suitable for all the spraying seeding technologies.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a grass fiber spraying substrate for sandy loam soil and a use method thereof. Background technique [0002] In recent years, due to the over-exploitation of the ecological environment, the degree of soil desertification and salinization has continued to intensify. Many soils are not suitable for the growth of grass seeds, which makes the application of guest soil spraying greening technology more important. Soil spraying greening technology has become one of the most widely used ecological slope protection technologies in Japan. The formula of the planting substrate is the core of the whole technology. It is very confidential in Japan, and there are relatively few specific reports. Soil spray matrix formula is particularly important. [0003] Fiber is one of the important components in the spray matrix. The main function is to improve the soil structure, as a c...
