A kind of liquor distiller's grains organic fertilizer and its preparation method and application

Abstract

The invention discloses white spirit vinasse organic fertilizer. Thermoactinomyces sacchari CP with high temperature resistance, ethanol resistance and acid and alkali resistant properties and existing decomposition bacteria are scientifically compounded, a vinasse decomposition agent is prepared, then the vinasse decomposition agent is directly inoculated into fresh white spirit vinasse, high-temperature composting can be rapidly carried out to form high-quality organic fertilizer without carrying out pretreatment such as deacidification and reduction of alcohol, treatment processes are reduced, manpower, material resources, financial resources and time are saved, time for entering a high temperature period is short (the temperature can reach 55 DEG C after one day and can reach 85 DEG C after three days), long high temperature fermentation time is maintained (the temperature of 83-85 DEG C can be maintained for three days), the fermentation period is shortened (15-16 days only) and is shortened for 26-27 days compared with existing preparation period, secondary pollution and putrefaction of vinasse and soil alkalinization are effectively prevented, the environment and soil are protected, yield and quality of the organic fertilizer are obviously improved, technical indexes and harmless indexes of the organic fertilizer completely accord with NY884 requirements, and a new shortcut is opened up for directly carrying out high temperature composting on the white spirit vinasse to produce high-quality organic fertilizer and applying the high-quality organic fertilizer to field vegetables to increase yield.

Description

technical field [0001] The invention relates to the preparation of distiller's grain organic fertilizer, in particular to a liquor distiller's grain organic fertilizer and its preparation method and application. Background technique [0002] Distiller's grains are the direct leftovers in the brewing process. At present, more than 50 million tons of distiller's grains need to be processed in my country. Therefore, people have been paying attention to the problem of disposing of distiller's grains after fermentation. Liquor distiller's grains are easily fermented and corrupted, and emit stench and easily pollute the environment. Because it contains a lot of crude fat, crude starch, crude protein and rich in nitrogen, phosphorus, potassium and polysaccharides, it is an excellent source of organic fertilizer. Therefore, the use of distiller's grains to make organic fertilizers can not only solve environmental problems, turn waste into treasure, but also provide high-quality org...

Problems solved by technology

[0010] Although there are many related technologies and patent documents on the preparation of distiller's grain organic fertilizer disclosed above, the practical application is not very mature, and most of them need to be pretreated by reducing the alcohol content of the distiller's grains, reducing the acidity, and adding auxiliary nutrients before inoculating the compost with a decomposing agent. , the process is complicated, wastes manpower, material resources, financial resources and time, and it will also cause incomplete decomposition of distiller's grains, resulting in secondary pollution and corruption. At the same time, there are defects such as low fermentation rate, long decomposition period of high-temperature composting, low organic matter degradation rate, and incomplete decomposition. Therefore, it is necessary to seek a method that can be directly inoculated with liquor distiller's grains for rapid high-temperature composting and decomposing to prepare high-quality organic fertilizer without the need for distiller's grain pretreatment and component adjustment.
