NOVELTY - Organic-inorganic compound fertilizer (I) comprises quick-acting nutrient fertilizer, slow-release nutrient fertilizer and organic nutrient fertilizer, where the raw materials comprise quick-acting nutrient fertilizer (20-40 part by mass (pbm)), slow-release nutrient fertilizer (20-40 pbm) and organic nutrient fertilizer (30-45 pbm); the quick-acting nutrient fertilizer is mixed and pelleted by urea (5-15 pbm), monoammonium phosphate (10-20 pbm) and potassium sulfate (2-10 pbm).    USE - (I) is useful for licorice. No biological data given.    ADVANTAGE - ADVANTAGE u (I) is economic, and can be prepared with improved quality and yield in a short period of time.    DETAILED DESCRIPTION - Organic-inorganic compound fertilizer (I), comprises quick-acting nutrient fertilizer, slow-release nutrient fertilizer and organic nutrient fertilizer, where the raw materials comprise quick-acting nutrient fertilizer (20-40 part by mass (pbm)), slow-release nutrient fertilizer (20-40 pbm) and organic nutrient fertilizer (30-45 pbm); the quick-acting nutrient fertilizer is mixed and pelleted by urea (5-15 pbm), monoammonium phosphate (10-20 pbm) and potassium sulfate (2-10 pbm); the slow-release nutrient fertilizer is mixed and pelleted by urea (5-15 pbm), potassium sulfate (3-12 pbm) and weathered coal (10-28 pbm) for 8-15 hours; the organic nutrient fertilizer is prepared by stacking, fermenting and mixing scarp (30-40 pbm), furfural residue (30-40 pbm), oil residue (20-30 pbm) and microorganism fermenting agent (1-2 pbm), adjusting moisture of the mixing material in 55-60 wt.%, stacking, and fermenting for 39-51 days to pellet; and the grain size of the raw material is 2-4 mm. An INDEPENDENT CLAIM is included for preparing (I) comprising (a) mixing and pelleting the urea, potassium sulfate and weathered coal to obtain quick-acting nutrient fertilizer, (b) uniformly mixing the urea, potassium sulfate and weathered coal, spraying uniformly, allowing the mixture to stand for 5-8 hours, stacking, pelleting, and obtaining slow-release nutrient fertilizer, (c) mixing the scarp, furfural residue, oil residue and microorganism fermenting agent at 55 degrees C, fermenting for 7-9 days, stacking, fermenting for 6-8 days, repeating the operation for 2 times, fermenting for 39-51 days, pelleting, and obtaining organic nutrient fertilizer, and (d) uniformly mixing the quick-acting nutrient fertilizer, the slow-release nutrient fertilizer and the organic nutrient fertilizer in a mixer.
