Barren land vegetation recovery compound preparation taking biologic materials as main bodies

Abstract

The invention discloses a barrel land vegetation recovery compound preparation taking biologic materials as main bodies. The barrel land vegetation recovery compound preparation comprises the following six components with additive amounts in each 100 square meters: 15-50kg of a biomass high-polymer material, a microbial fertilizer with more than 10<8> viable organisms, 1.5-10kg of a compound fertilizer, 0-5 kg of an air-hardening mineral material, 0-6kg of phosphate buffer system (pH 6.5-8.0), and 0-50kg of a color enhancing material. According to the barrel land vegetation recovery compound preparation, the prepared soil crusts have the effects of absorbing moisture, holding water, resisting rainwater erosion, resisting wind erosion, improving the surface temperature to promote the plant germination and growth, and prolonging the plant growth period. When the crusts are formed after the construction is completed, the surfaces of the crusts do not need coverings, later-period watering is not required, and vegetation with relatively high cover degree can be formed on target earth surfaces in a growth season. The barrel land vegetation recovery compound preparation is applied to the field of vegetation recovery and water and soil conservation of barren lands such as road slopes, project spoil slopes, mine slashes, abandoned farmlands, desertification lands and the like.

Description

technical field [0001] The invention relates to a composite preparation mainly composed of several kinds of biomass materials, in particular to a composite preparation mainly composed of biomass materials for restoring vegetation in barren land. 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 of human beings. [0003] Currently, the more advanced vegetation restoration methods for barren land in the market mainly include fiber-soil greening method (Fiber-soil Greening Method), high-order aggregate SF greening method (Soil Flock Greening method), continuous fiber greening method (TG greening method). These three construction methods are all thick-layer substrate spraying methods devel...

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.
