USE - Multi-element chelate compound fertilizer (claimed).    ADVANTAGE - The multi-element chelate compound fertilizer has reduced volatilization and excellent fertilizer efficiency. The multi-element chelate compound fertilizer improves soil fertility, and provides micronutrient deficiencies to soil.    DETAILED DESCRIPTION - A multi-element chelate compound fertilizer contains 8-12 pts. wt. chelate compound, 10-15 pts. wt. 45.8% nitrogen-containing urea, 5-10 pts. wt. potassium chloride, 5-10 pts. wt. magnesium chloride, 2-5 pts. wt. ammonium nitrate, 2-5 pts. wt. potassium nitrate, 5-10 pts. wt. potassium dihydrogen phosphate, 2-5 pts. wt. copper sulfate, 2-5 pts. wt. zinc sulfate, 2-5 pts. wt. ferrous sulfate, 2-5 pts. wt. manganese sulfate, 2-5 pts. wt. boric acid, 2-5 pts. wt. calcium citrate, 1-3 pts. wt. protective agent, and 1-3 pts. wt. release additive. The chelate compound is prepared by washing reeds, pampas grass and straw crops, crushing mixed materials, adding complex bacteria to mixture feed, further adding amino acid powder, ferrous sulfate, manganese sulfate, sodium borate and water, stirring for 2 hours, sealing, heat-preserving at 60-80 degrees C for 5 days, fermenting, adjusting pH to 7.4 to obtain humic solution, mixing mixed material and composite broth, adding amino acid powder, water, ferrous sulfate, manganese sulfate, boric acid and sodium citrate to reactor such that the weight ratio of mixed material, composite broth, amino acid powder and water is 1-1.2:0.2-0.3:0.1-0.15:20-30 and weight ratio of ferrous sulfate, manganese sulfate, sodium citrate and boric acid is 0.12-0.16:0.1-0.14:0.14-0.18:0.08-0.10, reacting mixture, adjusting pH to 6.8, heating at 68-76 degrees C for 0.5-1.2 hours to form chelation reaction liquid, transferring chelation reaction solution to chelating buffer tank and maintaining pH of chelate product to 6.8 at 68-76 degrees C for 30-40 minutes. An INDEPENDENT CLAIM is included for preparation of multi-element chelate compound fertilizer.
