Embodiment Construction

[0029] Those skilled in the art can refer to the content of this article to appropriately improve the process parameters to achieve. In particular, it should be pointed out that all similar replacements and modifications are obvious to those skilled in the art, and they are all considered to be included in the present invention.

[0030] In order to further understand the present invention, the present invention will be described in detail below in conjunction with examples.

[0031] A high-efficiency bio-organic fertilizer, the content of each component of the organic fertilizer is: organic matter (dry basis) 55-60%, total nutrient (dry basis) 6-7%, effective viable bacteria number 150-200 million / g.

[0032] The organic fertilizer is made by mixing and fermenting the raw materials in the following weight percentages: 65% cassava residue, 10% livestock and poultry manure, 15% crop straw and rattan shell, 3% fly ash, 3% superphosphate, and 2% fermented bacteria , Bacillus a...

Abstract

The invention relates to the technical field of organic fertilizer production, in particular to efficient bio-organic fertilizer and a preparing method thereof. The preparing method includes the steps that the aerobic fermentation technology is used, cassava alcohol biogas residues are mechanically dehydrated, auxiliary materials are added, aerobic microbial floras are inoculated, drying, smashing and pelleting are carried out, and composite functional bacteria are added; the organic fertilizer obtained after fermentation is prepared from, 40-60% of organic matter and 6-7% of total nutrients in units of the dry basis, and the effective viable count is 0.5-200000000 / g. The problems that an existing organic fertilizer production technology is long in fermentation period, a fermented product is low in fertilizer efficiency, secondary pollution is caused to the environment, long-term fertilizer application leads to soil hardening, and large-scale application is limited are solved. The obtained organic fertilizer meets the organic fertilizer detection standard of the department of agriculture, is high in fertilizer efficiency, short in fermentation period and particularly suitable for industrial large-scale production and avoids secondary pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer production, in particular to a high-efficiency biological organic fertilizer and a preparation method thereof. Background technique [0002] At present, one-third of my country's ethanol production uses cassava as raw material. However, a large amount of organic waste—cassava dregs will be produced in the production process of cassava alcohol. It is estimated that for every ton of cassava ethanol produced, about 0.7 tons of cassava dregs will be produced. Currently, most of the processing of a large amount of dregs is through anaerobic fermentation. Biogas production, this process produces a large amount of liquid biogas residue, the general disposal is landfill, which not only occupies a lot of land, but also causes soil and groundwater pollution. If it is not treated and used rationally, it will have a negative impact on the ecological environment, which is not conducive to the opt...
