NOVELTY - A wheat straw biological coal fertilizer comprises 25-30 pts. wt. apple slag, 2-3 pts. wt. zinc sulfate, 30-40 pts. wt. bagasse, 14-16 pts. wt. potassium nitrate, 2-3 pts. wt. levulinic acid, 4-6 pts. wt. Chinese cymbidium leaf juice, 25-35 pts. wt. plant ash, 120-140 pts. wt. fresh Enteromorpha, 5-6 pts. wt. composite microorganism inoculant, 260-280 pts. wt. wheat straw, and 30-34 pts. wt. fresh urine. The composite microorganism inoculant comprises rhizopus oryzae, Bacillus subtilis and Bacillus cereus at ratio of 1:2:2.    USE - Wheat straw biological coal fertilizer.    ADVANTAGE - The fertilizer greatly enhances soil organic humus content, dynamically adjusts soil nutrient status, strengthens supplying ability of soil as fertilizer, and has improved adsorption and controlled release of nutrients into the soil, improved fertilizer and slow-release nutrient ratio, and long-term support of nourishment for crops growth.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of fertilizer comprising (A) washing fresh Enteromorpha, crushing, adding apple slag, bagasse and plant ash, mixing, adding water, loading into fermentation tank, adjusting water content to 50-55%, adding composite microorganism inoculant, stirring to carry out fermentation, turning once every 4-5 days while controlling fermentation maximum temperature to not greater than 70 degrees C for 20-25 days, and filter pressing to obtain fermentation broth and fermentation residue; (B) crushing wheat straw, adding into carbonization kiln, heating to 400-500 degrees C to carry out carbonization for 2-3 hours, increasing temperature to 800-900 degrees C for 30-60 minutes to obtain wheat straw coal, taking out, and cooling to room temperature; (C) adding fermentation broth with Chinese cymbidium leaf juice and zinc sulfate, heating to 55-60 degrees C for 40-60 minutes, cooling to room temperature, adding potassium nitrate and levulinic acid, and stirring to obtain nutrient solution; (D) mixing with fresh urine, adding citric acid solution to adjust pH to 3.9-4.1, heating, concentrating, adding wheat straw coal to carry out adsorption, and drying; and (E) adding fermentation residue and remaining raw materials, mixing, granulating, weighing, and packaging.
