Abstract

The invention relates to a preparation and application method of a water-soluble environment-friendly sand-fixing agent, which is characterized in that: the natural seed gum solution is prepared by water immersion, and then humic acid and nitrogen fertilizer are added to obtain a mixed solution. The application method is: spray 3000-5000kg per mu The mixed liquid can be laid by strip spraying or spraying on the surface of quicksand according to the undulation of the moving sand surface. The sand-fixing agent of the invention has a simple preparation method, does not require special equipment, is suitable for field preparation, has cheap and easy-to-obtain raw materials, has obvious sand-fixing effect, does not affect plant growth, and has high salt tolerance. The sand-fixing agent of the invention has flexible application modes, and the sand-fixing effect can be maintained for a long time. After sand-fixation and afforestation, using this environmental-friendly sand-fixing agent to set up sand barriers will not cause the root system to be exposed and die due to wind erosion, and achieve the goal of low-cost comprehensive management of mobile sandy land under rain-fed conditions, and it reflects the characteristics of practicality, simplicity, cheapness, high efficiency and long-lasting .

Description

technical field [0001] The invention relates to a sand-fixing material, in particular to a preparation method of a water-soluble environment-friendly sand-fixing agent; the invention also relates to an application method of the sand-fixing agent, belonging to the fields of soil and water conservation and desertification control. Background technique [0002] Desertification is a natural or unnatural phenomenon in which the productivity of large areas of soil is reduced or lost due to factors such as drought and lack of rainfall, vegetation destruction, strong wind erosion, running water erosion, and soil salinization. China is one of the countries with severe desertification in the world. Therefore, sand control is an important means to combat desertification. [0003] Fixed mobile sand dunes are the most important content in the construction of sand prevention and control projects. On the other hand, the moisture in the mobile sand dunes is relatively good, but the wind e...
