Problems solved by technology

However, there are many disadvantages in the application of asphalt emulsion sand fixation: the efficiency of asphalt in stabilizing sandy soil is low, and the dosage is large; asphalt is hydrophobic, and a large amount of application will lead to a decrease in soil water seepage capacity and increased water loss, which is not conducive to plant growth; limited by the source of asphalt raw materials , the cost of large-scale promotion and use is too high
(2) Synthetic polymer sand-fixing agent is a kind of high

Abstract

The invention discloses a preparation method of a biological sand-solidification water-retention repairing agent which comprises repairing agents I and II. The repairing agent I is prepared by the following steps: mixing carboxy methyl starch and carboxymethyl cellulose according to a certain ratio, preparing a fluid suspension by the use of a certain concentration of alcohol, carrying out a crosslinking reaction by adding a cross-linking agent at a certain temperature, filtering, drying and crushing to obtain a solid, adding sodium ferric EDTA, boric acid, manganese sulfate, potassium dihydrogen phosphate and ammonium nitrate, and uniformly mixing to obtain a solid repairing agent I; and making the solid repairing agent I into an aqueous solution so as to obtain a liquid repairing agent I. The repairing agent II is a water-retaining agent prepared from crop straw used as a raw material. According to the invention, starch and cellulose are used as biomass raw materials, cause no pollution to the environment and can undergo biodegradation; and with the combination of a sand-solidification dust-depressor, the water-retaining agent and a fertilizer, the biological sand-solidification water-retention repairing agent can be used to rapidly improve desertified land and create good water and soil conditions for plant growth, survival rate of plants can be raised, and ecological and environmental quality can be improved.

Description

technical field [0001] The invention belongs to the field of cleaning technology, and in particular relates to a method for preparing a bio-sand-fixing water-retaining restoration agent by using modified starch and modified cellulose as raw materials in combination with a water-retaining agent and a plant nutrient solution. Background technique [0002] China is one of the countries with the most severe desertification in the world. In the 1950s and 1960s, the desertified land in my country expanded by 1560km every year. 2 , 2100 km in the 1970s and 1980s 2 , 2400 km in the 1990s 2 . With the accelerated development of desertification, sudden wind and sand disasters—sandstorms occur more and more frequently, seriously polluting the environment and causing huge economic losses; develop low-cost, high-efficiency, and environmentally friendly chemical sand-fixing polymer materials It is imperative. [0003] Chemical sand fixation is to apply organic or inorganic chemical ma...
