The invention provides a production process of a biological-organic-inorganic
ternary compound fertilizer which is prepared by the following steps: mixing
crop stalks, such organic components as
livestock manures and active biological agents, regulating the
carbon nitrogen ratio from 26 to 35, PH from 5.5-8.2 and
moisture from 40% to 65% according to the
organic matter contents of the
crop stalksand the
livestock manures, fermenting the mixture at minus15-75 DEG C for 20-50 days and ensuring the living
bacteria count to be 0.03-0.2 billion / g, carrying out turning and oxygenating, fermenting in deep tanks and
grinding on the mixture to prepare the biological organic fertilizers, mixing the biological organic fertilizers with the inorganic fertilizers and trace elements and simultaneously adopting the low-temperature
drying process after extruding
granulation and the
biological agent spraying and cooling technology. The method can greatly shorten the decay period, ensure little nutrientloss and little
generating capacity of sour gases in the processes of
fermentation and decay and complete decay and
fermentation, can enhance the
stress resistance of the crops, ensure obvious
disease-resistant effects and high survival rates of specific functional
bacteria and has wide application. Through field contrast tests, both the production and income are increased by 10-25% by applying the biological
organic fertilizer.
