The invention relates to an
organic fertilizer and a production method thereof, and particularly relates to a method for producing an
organic fertilizer by utilizing hickory hulls. The method comprises the following steps of: uniformly mixing
hull powder,
meal and superphosphate, inoculating the obtained mixture into a microbial inoculan I after
moisture is adjusted, and carrying out aerobic
fermentation under the turning condition; after
fermentation, inoculating a microbial inoculan II into the material, and then carrying out piled aging,
drying, crushing, sieving and packaging and the like to obtain a hickory
hull organic fertilizer. Aiming at the characteristics that
lignin in the
hull has a high content, and is difficult to break down,
trametes gallic which has strong adaptability and is capable of breaking down
lignin and
cellulose is added during the piled aging, paint enzymes and
lignin peroxidases generated in the growth process of the
trametes gallic can promote conversion of lignin to
humic acid, and simultaneously, lignin wrapped
cellulose is released; and after the
cellulose is treated at high temperature in the aerobic
fermentation process, the cellulose is changed in structure, so that the cellulose is easily utilized by microbes, the material is composted more thoroughly, and the content of
humic acid in the product is increased.
