Abstract

The invention relates to the technical field of liquid fertilizer preparation, and specifically discloses a preparation method of an organic liquid fertilizer for improving soil cadmium pollution. Themethod comprises the steps of crushing, fermentation, enzymolysis, filtration and concentration. In the fermentation stage, domesticated cadmium-enriched strains are added and the dosage is 0.1-0.2%of the mass of the raw materials; the concentration step comprises a first-stage concentration stage, a second-stage concentration stage and a third-stage concentration stage, a third-stage concentrated solution obtained in the third-stage concentration stage is introduced into a tail mixer, the third-stage concentrated solution and the domesticated cadmium-enriched strains are mixed, and the mixing temperature of the third-stage concentrated solution and the domesticated cadmium-enriched strains is 30-35 DEG C. The organic liquid fertilizer produced by the preparation method has an effectiveimprovement effect on soil with cadmium pollution.

Description

technical field [0001] The invention relates to the technical field of liquid fertilizer preparation, in particular to a preparation method for improving soil cadmium pollution organic liquid fertilizer. Background technique [0002] Organic fertilizers refer to fertilizers made from by-product resources rich in organic matter such as animal excrement or animal and plant residues as the main raw materials, which are fermented and decomposed. Organic fertilizer has the characteristics of improving soil, fertilizing soil, increasing soil nutrient activity, purifying soil ecological environment, ensuring high-quality, high-yield and high-efficiency vegetables, and is an irreplaceable fertilizer for high-quality vegetable cultivation. At present, the raw materials for the production of organic fertilizers mainly include: straw, soybean meal, chicken manure, cattle, sheep and horse manure, distiller's grains, vinegar grains, kitchen waste, river silt, sewer silt, etc. [0003] A...
