NOVELTY - An organic compound fertilizer comprises urea, potassium dihydrogen phosphate, hair, attapulgite, dimethyl sulfoxide, boron and zinc fertilizer mixture, ferrous sulfate, Rhizobium, Azotobacter chroococcum, nanocarbon, rhizoma curculiginis, golden larch bark, radix sophorae flavescentis, ligninase, plant ash, humic acid, dicyandiamide, livestock manure, and powdered EDTA chelated manganese.    USE - Organic compound fertilizer used for wheat, rice, corn, soybean, and rape.    ADVANTAGE - The fertilizer enhances cold-proof, drought and pest-resistant capabilities, and tensile strength of fiber and cotton crops; and improves yield and quality.    DETAILED DESCRIPTION - An organic compound fertilizer comprises 20-22 pts. wt. urea, 5.5-6 pts. wt. potassium dihydrogen phosphate, 5-8 pts. wt. hair, 10-12 pts. wt. attapulgite, 0.15-0.25 pt. wt. dimethyl sulfoxide, 0.1-0.3 pt. wt. boron and zinc fertilizer mixture, 10-13 pts. wt. ferrous sulfate, 0.1-0.3 pt. wt. Rhizobium, 0.1-0.3 pt. wt. Azotobacter chroococcum, 5-8 pts. wt. nanocarbon, 1-3 pts. wt. rhizoma curculiginis, 5-7 pts. wt. golden larch bark, 9-11 pts. wt. radix sophorae flavescentis, 3.5-3.8 pts. wt. ligninase, 23-28 pts. wt. plant ash, 10-15 pts. wt. humic acid, 0.5-0.8 pt. wt. dicyandiamide, 10-20 pts. wt. livestock manure, and 8-10 pts. wt. powdered EDTA chelated manganese. The weight ratio of boron and zinc fertilizer mixture is 1:0.5. The fertilizer is prepared by culturing Azotobacter chroococcum, adding 95-98 wt.% glucose and 2-5 wt.% 0.05-0.5 g/L ammonium sulfate solution, fermenting at 20-28 degrees C for 30-40 hours to form strain, adjusting pH to 5-5.5, cultivating Rhizobium, adding 95-97 wt.% cane sugar and 2-4 wt.% 0.5-2.5 g/L sodium chloride solution and 1 wt.% amylosucrase, fermenting at 30-40 degrees C for 30-40 hours, and adjusting pH to 5.5-6; adding 3-5 times 25-35% sulfuric acid in hair, adjusting pH to 5.5-7, hydrolyzing at 40-50 degrees C for 12-18 hours to form amino acid, adding lime, adding 2-3 pts. wt. carboxymethyl cellulose in every 10 pts. wt. hydrolyzate, adding urea, potassium dihydrogen phosphate and boron and zinc fertilizer mixture, and dissolving to obtain liquid fertilizer; soaking rhizoma curculiginis, golden larch bark and radix sophorae flavescentis in vinegar for 10-15 days, filtering to obtain filtrate, extracting with water or alcohol, freeze-drying, and sieving through 130-140 meshes to obtain medicine extract; mixing ferrous sulfate and nanocarbon at 0 degrees C for 2 hours, adding dispersant, high-shearing at 3x 104 revolutions/minute (rpm) for 2 hours, cooling to room temperature, decompressing, filtering, and drying at 110-120 degrees C to obtain nanoferrous sulfate; mixing plant ash and livestock manure, uniformly stirring, fermenting at 40-45 degrees C for 45-50 hours, turning once every 12 hours for 5-6 times, drying at 100-110 degrees C, crushing, and sieving through 85-95 meshes; mixing all components, ferrous sulfate, dimethyl sulfoxide, humic acid and dicyandiamide, stirring at 300-600 rpm for 1.5-2.5 hours, turning once every 10 minutes, adding attapulgite, ligninase and EDTA chelated manganese, grinding, uniformly stirring, and drying at 55-60 degrees C for 1.5-2.5 hours.
