Abstract

The invention relates to a preparation method for an organic soil improver, and belongs to the technical field of soil fertilizers and soil improvement. The organic soil improver is prepared by performing prepolymerization and polymerization on weakly alkaline waste water obtained by cleaning wool, and then performing solid-liquid separation and fermenting. The organic soil improver prepared by utilizing the weakly alkaline waste water produced in a wool cleaning processing process; a large amount of organic matters, amino acids and nutrients in the weakly alkaline waste water are utilized, sothat the pollution to the environment caused by the organic matters in the waste water is reduced; waste is reutilized; the characteristics of circular economy are met.

Description

technical field [0001] The invention relates to a preparation method of an organic soil conditioner, belonging to the technical field of soil fertilizer and soil improvement. Background technique [0002] Organic soil conditioner, also known as soil conditioner, refers to a material that can improve soil physical properties, promote crop nutrient absorption, and provide plant nutrients. The principle of action of organic soil conditioners is to bind many small soil particles to form large, water-stable aggregates. It is widely used in preventing soil erosion, reducing soil moisture evaporation or excessive transpiration, saving irrigation water, and promoting healthy plant growth. [0003] Organic soil conditioner has the functions of moisture retention and temperature increase, which can effectively improve soil moisture, increase the ground temperature of the plough layer, advance the growth period of crops by 2 to 7 days, and increase the soil moisture by about 5%. At t...
