Amino acid-containing cassava lees organic fertilizer and production method thereof

Abstract

The invention provides an amino acid-containing cassava lees organic fertilizer. The organic fertilizer contains the following raw materials in parts by mass: 800-900 parts of cassava lees, 175-250 parts of plant ash, 50-100 parts of plant protein and 0.2-0.4 part of composite strain. The organic fertilizer provided by the invention is prepared through fermentation by adopting cassava lees as main raw material, the organic content is over 60%, the content of total nutrients is over 8.5%, the content of total amino acids is over 1%, the content of nitrogen phosphorus and potassium is over 2.3, and the water content is about 27%, the organic fertilizer is slightly alkaline, the death rate of ascaris eggs exceeds 99%, and the requirements of NY525-2012 are met; and moreover, the cost is low, the fermentation time is short, the whole fermentation process is controllable, the problem of incomplete fermentation or excessive composting is overcome, the environmental pollution caused by solid wastes is effectively reduced in the alcohol production process, and the production requirements of environmental protection are met.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer production, in particular to an amino acid-containing cassava distiller's grains organic fertilizer and a production method thereof. Background technique [0002] In order to solve the energy problem, many countries vigorously develop the alcohol industry, but people have been paying attention to the problem of processing the distiller's grains after fermentation. The use of distiller's grains mostly depends on the fermented material. Distiller's grains from starch raw materials contain available protein and are usually used as feed sources for livestock. Distiller's grains from waste molasses raw materials can be mixed in livestock feed, but since fresh distiller's grains must be used as feed, And utilization is limited, so cause a large amount of distiller's grains to pile up idle, cause the pollution of environment. At present, more than 50 million tons of distiller's grains need to...

Problems solved by technology

The use of distiller's grains mostly depends on the fermented material. Distiller's grains from starch raw materials contain available protein and are usually used as feed sources for livestock. Distiller's grains from waste molasses raw materials can be mixed in livestock feed, but since fresh distiller's grains must be used as feed, And the use is limited, so a large amount of distiller's grains are left idle and piled up, causing environmental pollution

At present, more than 50 million tons of distiller's grains need to be disposed of in China, and most enterprises usually simply dispose of them by landfilling in garbage dumps or stacking them in the open air, which not only wastes resources, but also pollutes the environment
