The invention relates to a making technology of a biological
organic fertilizer, which belongs to the field of
crop straw deep processing, and in particular relates to a method for making the biological
organic fertilizer by using rice straws as a main
raw material. More specifically, rice straws are adopted as the main
raw material; animal wastes and pond
sludge are adopted as auxiliary materials; and the main
raw material and the auxiliary materials are fermented by EM (
Effective Microorganism) strain, which is enlarged in
multiple stages, so as to obtain the biological
organic fertilizer. The method for making the biological organic
fertilizer by using rice straws as the main raw material, provided by the invention, has the advantages of wide raw material source, low price, simple product making process and high
beneficial bacteria content in the formed product as well as has the characteristics of increasing
soil organic matter, improving the
soil structure, promoting the soil microbial activities, enhancing the
soil fertility keeping and
fertility supplying properties and the like; and the
crop yield is also obviously increased, the
crop quality is improved and the
fertilizer input can be reduced in the product application; therefore, the production cost is reduced and the farmer income is increased.
