Problems solved by technology

This type of existing bio-organic fertilizer has the following disadvantages: 1. The main organic raw material is livestock and poultry manure or paper-making filter mud, so the content of harmful bacteria and heavy metals is relatively high; Pollution; ③Livestock and poultry manure contains a variety of harmful bacteria and pathogens, which are easy to spread diseases; ④Livestock and poultry manure is easy to breed flies, which affects the surrounding production and life

Embodiment 1

[0010] Example 1: Using cassava residue and starch waste liquid as the main organic raw materials, the cassava residue stock solution with an initial water content of 98% is piped to a high-speed centrifugal dehydrator. After dehydration by the high-speed centrifugal dehydrator, the water content of the cassava residue drops to 76%. %; the cassava dregs after centrifugal dehydration are transported to the cassava dregs filter press by the belt conveyor, and after being filtered by the filter press, the water content of the cassava dregs is reduced to 60%; at this time, the appearance of the cassava dregs is loose, meeting the requirements for fermentation; The dehydrated cassava residue is transported to the fermentation workshop, adding 8% humic acid, 4% oil sour, 4% rice bran and 0.3% straw fermentation decomposer by weight of the dehydrated residue, and then sent to the fermentation tank for aerobic fermentation. Fermentation, the production control of aerobic fermentation i...

Embodiment 2

[0011] Example 2: Using cassava residue and starch waste liquid as the main organic raw materials, the cassava residue stock solution with an initial water content of 94% is piped to a high-speed centrifugal dehydrator, and after dehydration by the high-speed centrifugal dehydrator, the water content of the cassava residue is reduced to 78%. %; the cassava residue after centrifugal dehydration is transported to the cassava residue filter press by the belt conveyor, and after being filtered by the filter press, the water content of the cassava residue drops to 63%; at this time, the appearance of the cassava residue is loose and meets the requirements of fermentation; The dehydrated cassava slag is transported to the fermentation workshop, adding 10% humic acid by weight of the dehydrated slag, 6% oil sour and rice bran, and 0.4% fermentation decomposer, and then sent to the fermentation tank for aerobic fermentation. The production control of aerobic fermentation is carried out...

Embodiment 3

[0012] Example 3: Using cassava residue and starch waste liquid as the main organic raw materials, the cassava residue stock solution with an initial water content of 90% is piped to a high-speed centrifugal dehydrator, and after dehydration by the high-speed centrifugal dehydrator, the water content of the cassava residue drops to 80% %; the cassava residue after centrifugal dehydration is transported to the cassava residue filter press by the belt conveyor, and after being filtered by the filter press, the water content of the cassava residue drops to 65%; at this time, the appearance of the cassava residue is loose and meets the requirements of fermentation; The dehydrated cassava slag is transported to the fermentation workshop, adding 12% humic acid, 7% oil and rice bran, and 0.5% fermentation decomposer to the dehydrated slag, and then sent to the fermentation tank for aerobic fermentation. The production control of aerobic fermentation is carried out by the method of for...

Abstract

The invention belongs to the field of the manufacturing of organic fertilizers and discloses a method for producing an amino acid microbial organic fertilizer by using cassava residue and starch waste liquor. The method comprises the following steps of: dehydrating the cassava residue and the starch waste liquor until the final water content is 60 to 65 weight percent; adding 8 to 12 weight percent of humic acid, 3 to 7 weight percent of oil cake, 3 to 7 weight percent of rice bran and 0.3 to 0.5 weight percent of straw fermentation decomposing inoculant, and performing aerobic fermentation, wherein the fermentation temperature is 40 to 65 DEG C, and the fermentation cycle is 15 to 20 days; and uniformly mixing a functional strain which accounts for 3 to 5 percent of the total weight and is one or more of Bacillus mucilaginosus, bacillus subtilis, Bacillus licheniformis, Bacillus megaterium and Streptomyces jingyangensis, starch-containing waste liquor which accounts for 2 percent of the total weight and fermented residue, aerating the air and performing late curing for 5 to 7 days, and adding 1 to 3 percent of amino acid to obtain a finished product. Raw materials do not contain harmful bacteria and pathogens, harmful gas and odor are not generated in the fermentation, and the fertilizer can increase effect and stimulate plants to grow quickly.

Description

technical field [0001] The invention belongs to the field of organic fertilizer manufacture, and in particular relates to a method for producing amino acid bio-organic fertilizer by using cassava residue and starch waste liquid. Background technique [0002] Bio-organic fertilizer refers to a kind of microbial fertilizer and organic fertilizer that is composed of specific functional microorganisms and mainly animal and plant residues (such as livestock and poultry manure, crop straw, etc.) The fertilizer with organic fertilizer effect is an industrial product. Bio-organic fertilizer is a combination of microbial fertilizer and organic fertilizer. Compared with chemical fertilizers, it has the following advantages: ① Complete nutrition, containing a variety of nutrients; ② Rich in organic matter, it can improve soil fertility and prevent soil damage caused by chemical fertilizers. Compaction; ③ rich in microbial functional bacteria, which can improve the crop rhizosphere mic...
