Desertification soil water retention improvement structure and method
The invention relates to a desertification soil water retention improvement structure and method. The desertification soil water retention improvement structure comprises an enclosure frame, and a first sandy soil layer, a water retention layer, a second sandy soil layer, a surface strengthening layer and a one-way water guide assembly which are sequentially arranged in the enclosure frame from bottom to top; the first sandy soil layer comprises sandy soil and graphite powder in a mass ratio of 1: (0.005-0.03); the water-retaining layer comprises an organic decomposed material and a water-retaining agent in a mass ratio of 1: (0.05-0.2); the second sandy soil layer comprises sandy soil and bentonite in a mass ratio of 1: (0.005-0.05); the surface strengthening layer comprises hardened particles obtained by granulating fly ash, sandy soil and concrete in a mass ratio of (3-5): (4-6): 1; the one-way water guide assembly comprises a plurality of hook-shaped hollow pipes. According to the invention, a specific chemical component space distribution is constructed, and a physical space with super-strong water retention of a plant root system is formed. Compared with the prior art, the method has the advantages of being high in wind and sand resistance, high in raw material utilization rate, convenient in water pouring, good in water retention and improvement performance, remarkable in desertification control effect and the like.
本发明涉及一种荒漠化土壤保水改良结构和方法，包括围框，以及围框内从底部到上部依次设置的第一沙土层、保水层、第二沙土层、表面强化层，以及单向导水组件；所述的第一沙土层包含质量比为1：(0.005～0.03)的沙土和石墨粉；所述的保水层包含质量比为1：(0.05～0.2)的有机腐熟物料和保水剂；所述的第二沙土层包含质量比为1：(0.005～0.05)的沙土和膨润土；所述的表面强化层包含质量比为(3～5)：(4～6):1的粉煤灰、沙土和混凝土进行颗粒化得到的硬化颗粒；所述的单向导水组件包括多个弯钩型中空管。本发明构建出一个特异的化学组分空间分布，形成一个植物根系保水超强的物理空间。与现有技术相比，本发明具有抗风沙能力强，原料利用率高，浇注水便捷、保水改良性能好，荒漠化治理效果显著等优点。
