Problems solved by technology

[0011] Cow dung, straw, sludge, garbage and other composts produced by traditional processes, although they have high organic matter content and nutrients that promote plant growth, can also play a role in soil improvement, but due to low carbon content and low specific surface area, they cannot play a role. To buffer fertilizer nutrient release and soil pore regulation; cannot improve soil cation availability
Can't increase ground temperature, can't accelerate rooting, can't increase soil aggregate structure, can't improve resistance to wind erosion, can't keep soil moisture, can't increase stress resistance
Although active coke has a high carbon content and a large specific surface a

Abstract

A desertification and degeneration soil modifier is formed by mixing organic carbon with active coke powder according to the weight ratio of 1:0.1-0.3, wherein the organic carbon is formed by conducting destructive distillation on organic waste. A method for making the soil modifier includes the steps of firstly, preprocessing the organic waste; secondly, conducting destructive distillation on the preprocessed organic waste to form the organic carbon; thirdly, mixing the organic carbon with the active coke powder according to the weight ratio of 1:0.1-0.3 to obtain the desertification and degeneration soil modifier. The invention further discloses a device for making the desertification and degeneration soil modifier.

Description

technical field [0001] The invention relates to a sandy degraded soil improvement agent prepared by using organic waste and active coke. [0002] The invention also relates to a preparation method of the above-mentioned desertification degraded soil improver. [0003] The present invention also relates to the application of the above-mentioned sandy degraded soil improver in improving sandy degraded soil. [0004] The present invention also relates to equipment for preparing the above-mentioned sandy degraded soil improver. Background technique [0005] my country produces a huge amount of organic waste every year. According to statistics, Beijing alone produced 1 million tons of sewage treatment plant sludge, 10 million tons of domestic garbage, and 4 million tons of garden waste in 2013. There are more than 1 billion tons of organic waste in the world every year. waste. [0006] Organic waste includes: organic matter in municipal solid waste; agricultural crop stalks, ve...
