Problems solved by technology

If the heavy metals contained in the soil cannot be effectively treated, they will be absorbed and accumulated by crops, eventually endangering human health
At present, the treatment of heavy metals in the soil cannot be completely removed, and some of the remaining heavy metals are easily absorbed and enriched by plants

Abstract

The invention provides a technology for producing an organic chelating polyelement compound fertilizer through guniting. The technology comprises the steps that (1) a solid keratin substance is subjected to acidolysis with hydrochloric acid and dilute sulfuric acid; ammonia is supplied; neutralization and filtering are conducted; a compound amino acid solution is obtained; (2) peat and cleaned crop straw are crushed and mixed; compound bacterium liquid and ammonia water are added for fermentation; a potassium hydroxide solution is added; an active humic substance is obtained; (3) an antioxidant and inorganic salt with medium trace elements conduct chelation reaction with the compound amino acid solution and the active humic substance; a chelation product solution is obtained; (4) potassium chloride reacts with excessive sulfuric acid to generate mixed acid; mixed acid is mixed with hydrogen chloride and neutralized by ammonia; pelleting slurry is obtained; and (5) the chelation product solution and the pelleting slurry are driven into a guniting neutralization geosyncline, mixed uniformly, transferred into a pelletizer for guniting pelleting, and dried; and then the organic chelating polyelement compound fertilizer is obtained. The organic chelating polyelement compound fertilizer prepared by the technology is small in application amount, high in stability, and high in plant absorptivity.

Description

technical field [0001] The invention belongs to the field of production and preparation of compound fertilizers, and in particular relates to a process for producing organic chelating multi-element compound fertilizers by spraying. Background technique [0002] In recent years, nitrogen, phosphorus, and potassium compound fertilizers have been widely used. Due to the neglect of the addition of medium and trace elements, although the use of compound fertilizers has increased, the yield of crops has not been effectively improved, but crop diseases have aggravated , land and water pollution. To solve this problem, researchers have gradually realized the importance of adding trace elements in food. At present, most of the compound fertilizers containing medium and trace elements on the market simply add inorganic salts or oxides of medium and trace elements to nitrogen, phosphorus and potassium compound fertilizers. Due to the solidification of the soil and the antagonism betwe...
