Compound preparation for vegetation restoration of nutrient barren land as well as preparation method and use method of compound preparation

Abstract

The invention discloses a compound preparation for vegetation restoration of nutrient barren land. The compound preparation is prepared from the following raw materials in parts by weight: 15-50 parts of a biomass polymer material, 0-50 parts of an air-hardening material, 1.5-10 parts of composite fertilizer, 0-6 parts of a phosphate buffer system, 0-50 parts of a burnishing material and 1 part of microbial fertilizer containing 108 or more viable bacteria. The compound preparation can be applied to the barren land and can form crust with local soil on the land surface with no addition of external soil, and has functions of absorbing moisture, retaining water, resisting evaporation, resisting rain erosion, resisting wind erosion, increasing surface temperature, increasing soil fertility, promoting germination and growth of plants and prolonging plant growth stage and the like. The invention also discloses a preparation method and a use method of vegetation restoration of the nutrient barren land to provide those skilled in the art with technical support for preparation and use. Besides, after construction is completed and the crust is formed, coverage on the surface and later artificial water replenishment are unnecessary, and higher vegetation coverage can be formed on the target land surface within one growing season.

Description

technical field [0001] The present invention relates to the technical field of barren land vegetation restoration and water and soil conservation, in particular to a kind of composite preparation with several biomass materials as the main body, in particular to a compound preparation for vegetation restoration of barren land and its preparation method and its use method; The preparation refers to a mixture of one or several biological source materials, nitrogen-fixing bacteria microbial fertilizer, one or several air-hardening mineral materials, compound fertilizer, phosphate buffer system, and one or several color-enhancing materials. Background technique [0002] Barren land is widely distributed, but due to the lack of nutrients and water needed for plant growth, it is difficult for plants to grow, which has a serious impact on the human living environment. Therefore, the restoration of barren land vegetation is of great significance for improving the living environment o...

Problems solved by technology

In addition, vegetation-type porous concrete is still in the research stage, and it is difficult to apply it in practice due to its high cost.

[0004] Generally speaking, the above method has the following defects: ①The construction cost is high, and the vegetation maintenance workload in the later period is heavy, and the maintenance cost is also high; ②The use of local native plant populations is less considered, and the usual plant species are used, and the environmental adaptability is slightly poor; ③ The ecological safety and accessibility of some foreign soil and related construction materials are not good

Therefore, the rapid vegetation restoration technology commonly used at present is costly to promote and apply to large areas of barren land for vegetation restoration, and the environmental adaptability is average.
