Abstract

The invention discloses a desertified soil conditioner and a preparation method thereof. The desertified soil conditioner is prepared from the ingredients in parts by weight: 20 to 40 parts of coal gasification ash, 30 to 40 parts of plant straw, 1 to 2 parts of potassium hydroxide, 5 to 8 parts of hydroxymethyl cellulose, 15 to 20 parts of animal dung, 0.2 to 0.3 part of glucose, 0.2 to 0.3 partof corn flour and 2 to 5 parts of bacillus subtilis. The preparation method comprises the steps: smashing the plant straw, evenly mixing with the coal gasification ash and the hydroxymethyl cellulose,adding into a curing kettle, adding potassium hydroxide and curing for 24 hours under the conditions of 90 to 110 DEG C and 1.5 to 2.0 atmospheric pressure; cooling the cured materials to the room temperature, evenly mixing with the animal dung, the glucose, the corn flour and the bacillus subtilis and fermenting for 7 to 10 days to obtain the desertified soil conditioner. According to the desertified soil conditioner disclosed by the invention, a porous structure of the coal gasification ash is utilized; under the assistance of the organic macromolecular hydroxymethyl cellulose, the conditioner has good water retention; thus, the problem of quick penetration and evaporation of water in desertified soil is solved.

Description

technical field [0001] The invention relates to a sandy soil improver and a preparation method thereof, belonging to the field of solid waste recycling. Background technique [0002] Soil desertification generally refers to the process of turning good soil or usable land into sandy soil or land or even desert. 43% of the earth's surface is distributed in arid regions, and more than 110 countries are affected by land desertification, which causes a huge loss of 42 billion U.S. dollars every year in the world. my country is one of the countries most seriously endangered by desertification in the world. my country's desertified land area reaches 1.743 million square kilometers, accounting for 18% of the country's land area, involving 841 counties (banners) in 30 provinces (autonomous regions, municipalities) across the country. The eight major deserts and the four major sandy lands are the main sand sources in my country, and there are sporadic sandy lands along the rivers, r...
