Problems solved by technology

Giving full play to the ecological self-repair ability is the main method of soil and water conservation ecological construction. Through ecological self-repair, it can promote vegetation recovery, improve the ecological environment, and speed up the prevention and control of water and soil loss. However, relying solely on the ecological self-repair ability to restore vegetation and improve the ecology There is a disadvantage of slow governance process
Through the manual implementation of earth and stone works, the areas with serious water and soil erosion are reinforced by building slope protection, retaining walls, nailing wooden piles, etc., but it is characterized by quick results and obvious effects, but it requires a lot of investment and labor

Abstract

The invention discloses a water retention material for preventing water and soil loss and a preparation method thereof, and belongs to the technical field of water and soil conservation. The water retention material comprises an upper layer and a lower layer, the upper layer is a degradable material net, the lower layer is an inverted filter layer, the upper layer and the lower layer are connected through a bonding layer, and the inverted filter layer is composed of composite inorganic spheres. The preparation method comprises the following steps: weighing the straw fiber, the ceramic, the fly ash, the organic fertilizer, the super absorbent resin, the seeds and the quartz sand, mixing and granulating to prepare composite inorganic spheres; cutting a degradable material net, brushing a bonding layer on the surface layer of the degradable material net, paving the composite inorganic spheres on the surface of the bonding layer, and naturally drying to obtain the water retention material for preventing water and soil loss. The water-retaining material is square, can be laid and spliced during use, is convenient and rapid, is suitable for large-area operation construction, is wide in raw material source and simple in preparation process, and has a remarkable effect on water and soil loss treatment.

Description

technical field [0001] The invention relates to a water-retaining material for preventing water and soil loss and a preparation method thereof, belonging to the technical field of water and soil conservation. Background technique [0002] Soil erosion refers to the fragmentation and loosening of soil structure under the infiltration and impact of water. Concentrated slopes, heavy rainstorms, loose surface soil, and sparse vegetation are the natural causes of soil erosion. Inappropriate behaviors such as wasteland reclamation, reclamation along steep slopes, overgrazing, blind expansion of cultivated land, indiscriminate logging, development and construction are the man-made causes of soil erosion. Soil and water loss will lead to the decline of soil fertility, the decline of environmental quality and the imbalance of ecological balance. Therefore, it is urgent to increase the control of soil and water loss. [0003] At present, according to the current situation, the main d...
