Abstract

The invention discloses a method of producing an organic fertilizer by utilizing waste tobacco stems and grain stillage. The method comprises the following steps of adopting leftover waste generated in a flue-cured tobacco producing process and / or low-level flue-cured tobaccos generated when a tobacco grower produces flue-cured tobaccos as organic fertilizer raw materials, crushing into particles with particle size not greater than 2mm, mixing with fresh chicken manure in a mass ratio of 7:3, and sufficiently mixing with a microbial fermentation fungicide uniformly in the mass ratio of 10:1 by mechanical stirring; stacking and fermenting under the normal temperature, turning while increasing the material temperature to 70 DEG C, so repeatedly, wherein moisture content is not greater than 25% after 15-25 days; fine-processing thoroughly decomposed fermentation materials to obtain a powdered or granular refined organic fertilizer. According to the method disclosed by the invention, fermentation time is shorter, maximum temperature is moderate, moisture content is less, pH value of mixed fermented materials is lower after fermenting for 20 days, odor is smaller and fermentation effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of bio-organic fertilizers, in particular to a method for producing organic fertilizers by using waste tobacco stems and distiller's grains. Background technique [0002] my country not only ranks first in the world in tobacco planting area and output, but also is a big cigarette producer, with a huge amount of tobacco leaf waste. In the past, waste tobacco rods were mostly disposed of by incineration and landfilling. However, criminals used the extracts of waste tobacco rods to make counterfeit cigarettes from time to time. In order to fundamentally cut off the source of raw materials for counterfeit cigarettes and cigarette substitutes, the State Bureau has made strict regulations on the destruction of waste tobacco rods. Afterwards, it was difficult for various cigarette factories and flue-cured tobacco plants to fundamentally destroy the waste tobacco rods for a while, resulting in a large amount of tob...
