Embodiment

[0028] The method for compounding organic fertilizer with potato dregs and livestock and poultry manure comprises the following steps:

[0029] A: material preparation

[0030] A1: Adjust the water content of fresh potato residues to be fermented to 6%, mix them evenly and wait for inoculation;

[0031] A2: Dehydrate, dry, and pulverize livestock and poultry manure, straw, and soybean meal respectively, and then mix them evenly in a ratio of 5:2:2 according to the mass ratio to obtain mixture I, which is to be fermented;

[0032] A3: Bagasse is dehydrated, dried, crushed and passed through a 100-mesh sieve for later use;

[0033] B: fermentation

[0034] B1: Mix fresh potato residue, α-amylase, and bagasse in a mass ratio of 90:0.1:1, ferment at 50°C for 4 days, then cool the potato residue fermentation product I to 28°C, add Composite degradation bacteria agent, fermented for 2 days to obtain the potato dregs fermentation product II;

[0035] B2: Mix the mixture I and the...

Abstract

The invention discloses a method for compounding organic fertilizer through potato residues and livestock manure and belongs to the technical field of biological fertilizer. According to the method, the potato residues and the livestock manure are combined to be fermented through enzymolysis, on the one hand, harmful substances in the livestock manure are completely degraded, foul smells are eliminated, the organic fertilizer has faint potato aroma, and the situation that tillage for crops is not convenient when the smell of the livestock manure is pungent and unpleasant is reduced, and on the other hand, the added potato residues balance amino acid, vitamin B2 and other nutrient substances which are in shortage in organic fertilizer formed just through fermentation of livestock manure, reduce the adding amount of artificially synthesized chemical substances in the organic fertilizer, improve soil fertility and increase the crop yield.

Description

technical field [0001] The invention relates to the technical field of biological fertilizers, in particular to a method for compounding organic fertilizers by using potato dregs and livestock and poultry manure. Background technique [0002] my country is the world's largest potato producer, with a planting area of ​​80 million mu and an output of more than 80 million tons. It is mainly made into vermicelli, vermicelli, starch, etc. Potato residue refers to the wet potato residue obtained after potatoes are crushed, solid-liquid separated, washed and destarched for many times, and dehydrated by pressure filtration. The water content is 80-85%, and it contains 10-16% cellulose and hemicellulose. A small amount of crude protein, amino acids and vitamins and other nutrients. Long-term stacking of potato residues and juices will produce unpleasant smells, and traditional processing methods such as: microbial solid-state fermented protein feed, extraction of dietary fiber, and ...
