Humic acid slow-release organic compound fertilizer taking bovine rumen complex flora dry powder as core

A humic acid slow-release organic compound fertilizer taking dry powder of bovine rumen complex flora as a core belongs to the technical field of fertilizer science, and is prepared by culturing bovine rumen complex flora, then drying a bovine rumen complex flora base material into paste at low temperature, the number of bacteria in the bovine rumen complex flora base material is more than 10 million/ml, and then adding the dry powder of bovine rumen complex flora into the paste to prepare the humic acid slow-release organic compound fertilizer. The muddy bovine rumen composite flora base material is conveyed into the pelleting hole (1) from the core feeding funnel (5) and the core feeding pipe (6), and the device for processing and manufacturing the humic acid slow-release organic compound fertilizer particles with the bovine rumen composite flora dry powder as the core is composed of the pelleting hole (1), a hole fixing plate (2), a power line (3), a power line plug (4) and a pill receiving plate (34).
