Organic/inorganic composite fertilizer prepared from molasses fermentation liquor

Abstract

The invention provides an organic / inorganic composite fertilizer prepared from molasses fermentation liquor. How to effectively treat molasses fermentation fertilizer liquor generated by sugar plants, alcohol plants, cassava starch plants, yeast plants, monosodium glutamate plants and the like has become an urgent environmental problem and a severe economic problem ever since 1980-1990; and how to change wastes into valuable substances, solve the environmental problems and bring in considerable benefits becomes a long-term troublesome problem of the technical field. Ferrous sulfate and anaerobic bacteria are creatively combined to remove odor of the molasses fermentation liquor, dissolve part of organic matters and maintain rich nitrogen, phosphorus, potassium, humic acid, amino acid and other necessary minor elements for plants; and degumming and spraying granulation are performed to obtain the solid organic / inorganic composite fertilizer which is low in cost and suitable for industrialized production, thereby opening up a brand-new industry for the technical field.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a compound fertilizer made from molasses fermented liquid. Background technique [0002] Guangxi is one of the most suitable regions for growing sugarcane in the world, and it is the dominant sugarcane producing area in my country. The yield and sugar content of sugarcane have surpassed those of Cuba and Australia, reaching the level of Brazil and other major sugar-producing countries. Sugarcane is the economic crop with the largest planting area in Guangxi. In 2009, the spring planting area of ​​sugarcane was 10.314 million hectares (15.471 million mu). The target requirement of "by 2020, the sugar production capacity will reach about 12 million tons", that is, to increase the sugar production by nearly 41% in about 7 years from the 8.5 million tons of sugar production in the 2012 / 2013 crushing season Guangxi sugar industry will usher in a period of rapid developm...

Problems solved by technology

[0003] Since the 1990s, there have been patent documents reporting about molasses fermented liquid as a fertilizer. Until the beginning of the 21st century, the technical solution still stays in the use of molasses fermented liquid or the concentrate of molasses fermented liquid to be directly used as fertilizer in the field, but because it is not easy to After transportation and application, it needs to be covered with film, so it has not been introduced to the market on a large scale

But still fail to solve its mechanism of doing like this, cause the difference of adopting strain to cause the effect of fermentation to be different, product quality can not be effectively guaranteed, and do not take effective deodorization measure, the compound fertilizer that produces may have peculiar smell and Affect production, transportation and sales
