Embodiment Construction

[0013] Such as figure 1 As shown, intuitively and truly reflect the characteristics that the present invention explains the use of sand-fixing sand barriers. The technical key of the present invention is the composition of matrix additives and their proportional relationship, and the selection of fiber bags of appropriate size and their configuration and density on the surface of mobile sand dunes is based on the morphological characteristics of tall, large and dense mobile sand dunes.

[0014] 1) Material selection

[0015] Material: Fiber bags made of decomposable substances, such as gunny bags, straw bags, anti-aging woven bags, etc., with a size of 1.0m.

[0016] Substrate composition: Substrate additives in each basic sandbag and its composition are: 30kg of flowing sandy soil, 1kg of powdered sheep manure, 2kg of crushed and rotten plant straw or corncobs, 1kg of peat, 2kg of clay, 100g of water-retaining agent, biological 30g of bacterial fertilizer, 2g of germinating...

Abstract

The invention discloses a structure method of a biological fertilizer island sand-stabilizing sand-protecting barrier. The method comprises the technical steps of forming composite bodies through a certain number of foundation sandbags according to various shapes, enabling a range of the sizes of the composite bodies to be 2-5m, enabling a range of the size of an arrangement mode unit to be larger than 20m and the like. Matrix additives in the foundation sandbags are composed of moving aeolian sandy soil, powder-shaped decomposition sheep manure, smashed and decaying plant straw or corncobs, peat, clay, water-retaining agents, multi-strain biobacterial manure and plant seeds with germination capacity. The foundation sandbags and composite sandbags are arranged in shapes of an island shape, a straight line shape, a crescent moon shape and the like on the surface of a moving dune according to different arrangement modes, and the sand-protecting barrier which integrates functions of wind erosion control, local soil environment improvement, vegetation recovery and the like into a whole and is used for managing the moving dune is formed.

Description

technical field [0001] The invention relates to a sand-fixing method for comprehensive management of mobile sandy land, in particular to a construction method of a biological fertilizer island for sand-fixing and sand barriers. Background technique [0002] Fixed mobile sand dunes are the most important content in the construction of sand prevention and control projects. On the one hand, the mobile sand dunes are highly mobile and harmful, so they must be effectively managed and controlled; on the other hand, the water in the mobile sand dunes is relatively good, but the wind erosion is serious, and it is easy to survive and difficult to preserve when artificial vegetation is established. Therefore, taking effective technical measures to control wind erosion of mobile sandy land is the key link to establish vegetation and control mobile sand dunes. [0003] Sand barriers are commonly used and effective technical measures in the construction of sand prevention and control pr...
