Efficient biochemical fulvic acid preparing process

Abstract

The efficient biochemical fulvic acid preparing process is to utilize, enrich and culture humic acid producing bacteria and auxiliary bacteria existing in nature to form specific fulvic acid producing bacteria. The fermented material includes crop stalks, saw dust and other agricultural and forest waste and some inorganic nutrient components as well as fulvic acid producing bacteria, and through controlling nutrients compounding ratio, water content, temperature, humidity and other technological parameters, fulvic acid is produced through directional fermentation. The present invention has the advantages of short fermentation period, low cost, high fulvic acid content, high product quality and easy control of the production process. The fermented product contains great amount of fulvic acid, amino acid, nucleic acid and other matters, and may be used widely in plantation, stockbreeding, aquiculture, industrial fermentation, medicine, pesticide and other industry.

Description

technical field

[0001] The invention relates to a high-efficiency preparation method of biochemical fulvic acid. Background technique

[0002] Fulvic acid is a kind of organic macromolecular compound with physiological activity, which has been widely used in industry, agriculture, forestry, animal husbandry, aquaculture, medical daily chemical and other industries. For a long time, people have relied on the extraction of humic acid substances from natural resources such as lignite and weathered coal, which not only has a complicated extraction process, but also consumes a large amount of coal resources. In recent years, people have successfully produced fulvic acid substances by imitating the formation conditions of humic acid substances in nature and using bio-fermentation technology, realizing the industrialization and large-scale production of fulvic acid substances. However, the current production process of biochemical fulvic acid is not standardized, and there are man...
