NOVELTY - Producing organic complex plant fertilizer comprises (i) fermenting horse dung, mule dung or donkey dung to obtain high temperature cellulose decomposing bacteria liquid, (ii) fermenting livestock and poultry manure to obtain room temperature carbon-nitrogen decomposing bacteria liquid, (iii) preparing 2% aqueous agricultural rare earth solution, (iv) preparing aqueous microelement mixture solution, (v) mixing corn stalk leaves, ammonium bicarbonate, bone meal and potassium salt with products obtained in above steps, (vi) fermenting to obtain humification product, (vii) drying and granulating.    USE - The method is useful for producing organic complex plant fertilizer (claimed).    DETAILED DESCRIPTION - Producing organic complex plant fertilizer comprises (i) diluting horse dung, mule dung or donkey dung using 10-20 times of water and fermenting at 50-80 degrees C for 15 days to obtain high temperature cellulose decomposing bacteria liquid, (ii) diluting livestock and poultry manure using 5-20 times of water and fermenting at 25-35 degrees C for 30 days to obtain room temperature carbon-nitrogen decomposing bacteria liquid, (iii) preparing 2% aqueous agricultural rare earth solution, (iv) preparing zinc sulfate, manganese sulfate, boric acid, ferrous sulfate, magnesium sulfate and ammonium molybdate aqueous microelement mixture solution, (v) mixing corn stalk leaves, ammonium bicarbonate, bone meal, powdered rock phosphate and potassium salt with aqueous agricultural rare earth solution, aqueous microelement mixture solution, high temperature cellulose decomposing bacteria liquid and room temperature carbon-nitrogen decomposing bacteria liquid, (vi) adding the resulting mixture into a sealed fermentation tank, fermenting at 65-70 degrees C for 15 days, and then incubating for 4 months at 25-35 degrees C to obtain humification product, (vii) drying the humification product to moisture content of less than 10%, adding urea and calcium superphosphate, mixing uniformly and granulating.
