Embodiment

[0042] In the southern edge of Mu Us, Dajihan Village, Yuyang District, Yulin City, select 200m 2Two pieces of land with the same area were used to carry out the sand-fixing test of the sandstone sand barrier. First, in one of the sandstone areas, a large piece of sandstone was selected on the spot, and a rotary tiller (model: 1GKN-250; power: 58.8~73.5kW; manufacturer : Lianyungang Shuangya Machinery Co., Ltd.), crushed into 0.08m-diameter Pisha sandstone block particles, laying Pishasha sandstone sand barrier unit is square, with a side length of 10m, an edge strip coverage width of 0.9m, and a laying height of 0.1m , the sand is surrounded in the middle, and finally, the sandstone sand barrier units are arranged continuously in the shape of a character. On another piece of sandstone land, no sandstone sand barrier was laid out, and the sand-emission wind speed and the erosion amount of sandy soil at different wind speeds were measured with and without the sandstone grid san...

Abstract

The invention relates to a sand mixing method of a pisha sandstone sand-protecting barrier. The problems that an existing sand fixing sand-protecting barrier is poor in sand fixing effect, small in sand fixing area, high in sand-protecting barrier cost, large in environment protection and not beneficial to plant growth are solved. The adopted technical scheme comprises the steps of pisha sandstoneselection and preparation, pisha sandstone sand-protecting barrier unit design, pisha sandstone sand-protecting barrier arrangement and the like. According to the sand mixing method, local materialsare used by the pisha sandstone sand-protecting barrier, cost is saved, a good sand fixing function is achieved in various stages in the use process, and the method is friendly to the environment, free of pollution simple, practicable and capable of being implemented within a large area. The sand fixing method is suitable for effective utilization of sand fixing and vegetation in the pisha sandstone area of the Erdos plateau and can also be widely popularized to other pisha sandstone areas.

Description

technical field [0001] The invention belongs to the technical field of soil and water conservation and desertification prevention and control, and in particular relates to a sand-fixing method for sandstone sand barriers. Background technique [0002] The Ordos Plateau is located in the agro-pastoral ecotone on the southern edge of the Mu Us Desert, the transition zone between the Ordos Platform and the Loess Plateau, and has become the origin zone of water and sandstorms. The soil in this area is mainly arsenic sandstone soil, loess soil, aeolian sandy soil and alluvial soil. Pisha sandstone is a kind of loose rock formation, continental clastic rock series, which is as hard as a rock without water, soft as mud when exposed to water, and weathered and eroded when exposed to wind. It is known as "the most water and soil loss in the world" and " Environmental Cancers". The structure of the sand is loose, leaking water and fertilizer, unable to form a soil aggregate structur...
