Special fertilizer for Chinese goosebeery and preparation process thereof

Abstract

A special fertilizer for Chinese goosebeery is prepared by oxidizing and modifying humic acid into humate and adding nitrogenous fertilizer, phosphorus fertilizer and potash fertilizer. The preparation process comprises the following steps: (1) humic acid modification: oxidizing humic acid material with oxidizing acid and adding sulphite for modification to obtain humate; (2) chelation: adding potash fertilizer and compound fertilizer auxiliary material into the humate, and leading steam into a reaction kettle, heating to more than 80 DEG C and preserving the temperature for chelation for more than 8 h; (3) mixing: after the chelation, adding nitrogenous fertilizer and phosphorus fertilizer and mixing; and (4) thickening: adding micro conditioner for thickening, measuring and packing. In the invention, through adding modified HA salt, the original special fertilizer (M fertilizer) for Chinese goosebeery is further processed, and the pure inorganic fertilizer in the M fertilizer is changed into an organic-inorganic compound fertilizer with different characteristic, so that the operating factor of the fertilizer is improved by 14 percent through the fertilizer modification.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, in particular to special compound fertilizer for kiwi fruit. Background technique [0002] As early as 1850, nitrogen and phosphorus binary mixed fertilizers had been sold in the United States. After the 1930s, starting from Western European countries, with the improvement of crop yields, the increase in the number and variety of chemical fertilizers, and the development of agricultural mechanization, people are eager to change the traditional fertilization method of several unit fertilizers applied in batches to adapt to Intensive and high-efficiency agricultural production requirements. In the primary stage of compound fertilizer production, farmers mix several single fertilizers and apply them. With the increasing improvement of the chemical fertilizer industry, especially the combination of the development of the extraction phosphoric acid industry and the production process o...

Problems solved by technology

[0013] Humic acid (HA) is a macromolecular organic compound that widely exists in soil, salty and fresh waters and their sediments, carbonaceous deposits such as peat and coal mines in nature. It is decomposed by microorganisms and a series of geochemical The second process is formed, people call peat, weathered coal, etc.; the company's original formula is now using weathered coal, crushing the weathered coal, after ammoniation, the water solubility rate is low, the fertilizer efficiency utilization rate is low, and the synergistic effect on chemical fertilizers is not obvious, it is The main problems in the original formula of compound fertilizer (M fertilizer)
