NOVELTY - Rice plant organic-inorganic complex fertilizer comprises sweet potato vine, dry reed, biological charcoal, hawthorn pulp, Sophora japonica residue, crab shell, livestock manure, effective microorganism strain, urea, potassium chloride, calcium nitrate, silicate, yellow phosphorus slag, monoammonium phosphate, dicyandiamide, urea formaldehyde, borax and zeolite ore powder.    USE - Used as rice plant organic-inorganic complex fertilizer.    ADVANTAGE - The complex fertilizer: improves paddy soil fertility; improves rice soil environment; controls rice disease occurrence; increases rice yield and improves rice quality; increases nutrient resource utilization efficiency; coordinates soil nutrient balance; is good for soil fertility; and achieves sustainable high yield of rice.    DETAILED DESCRIPTION - Rice plant organic-inorganic complex fertilizer comprises 25-30 pts. wt. sweet potato vine, 9-14 pts. wt. dry reed, 14-17 pts. wt. biological charcoal, 10-12 pts. wt. hawthorn pulp, 13-16 pts. wt. Sophora japonica residue, 5-8 pts. wt. crab shell, 8-11 pts. wt. livestock manure, 2-3 pts. wt. effective microorganism strain, 19-22 pts. wt. urea, 12-17 pts. wt. potassium chloride, 15-16 pts. wt. calcium nitrate, 7-12 pts. wt. silicate, 18-20 pts. wt. yellow phosphorus slag, 5-9 pts. wt. monoammonium phosphate, 6-7 pts. wt. dicyandiamide, 3-4 pts. wt. urea formaldehyde, 20-25 pts. wt. borax, and 14-15 pts. wt. zeolite ore powder. An INDEPENDENT CLAIM is also included for preparing the rice plant organic-inorganic complex fertilizer, comprising (i) smashing the sweet potato vine, dry reed and crab shell, mixing together with the biological charcoal, hawthorn meal, S. japonica residue and livestock manure, adding effective microorganism strain to the mixed material, stirring uniformly, keeping water content at 25-35%, fermenting for 10-14 days, turning, conveying into a tower type fermentation plate, fermenting for 12-15 days to obtain organic fermented product, carrying out aerobic fermentation, then mixing with quail manure, calcium-magnesia phosphate fertilizer, wine lees powder and humic acid containing water content of 25% to the fermented product, discharging from the fermentation tower when there is no odor, after fermenting, fully and uniformly mixing the quail manure, calcium-magnesia phosphate fertilizer, wine lees powder, humic acid and calcium powder, zeolite powder, and potassium chloride, smashing, screening, detecting, and finally granulating into powder to obtain rice fertilizer finished product, (ii) uniformly stirring and mixing the urea, potassium chloride, calcium nitrate, silicate, yellow phosphorus slag, monoammonium phosphate, dicyandiamide, urea formaldehyde, borax and zeolite powder to obtain an inorganic mixture, (iii) uniformly stirring and mixing the organic fermented product and inorganic mixture, conveying into a pelletizer, coating and granulating to obtain organic-inorganic complex fertilizer particle, and (iv) drying the complex fertilizer particle at temperature of 35-40 degrees C for 18-20 hours, cooling, and packaging.
