NOVELTY - Biological organic and inorganic compound fertilizer comprises peat, urea, diammonium phosphate, potassium sulfate, magnesium sulfate, borax, copper sulfate, zinc sulfate, manganese sulfate, ammonium molybdate, bentonite, functional bacterial fermentation liquor (comprising flour, brown sugar, microbial inoculum and water), and photosynthetic bacterial liquid (comprising flour, brown sugar, photosynthetic bacteria and water).    USE - The fertilizer is useful for promoting growth of leaf, branch and root system of plant, inducing plants to absorb nitrogen, phosphorus and biological activity form soil.    ADVANTAGE - The fertilizer utilizes magnesium and sulfur elements from loosening soil, and meets the product quality index in accordance with national standard GB18877-2009 of the organic-inorganic compound fertilizer standards.    DETAILED DESCRIPTION - Biological organic and inorganic compound fertilizer comprises 35 pts. wt. peat, 25 pts. wt. urea, 17 pts. wt. diammonium phosphate, 16 pts. wt. potassium sulfate, 3 pts. wt. magnesium sulfate, 0.5 pts. wt. borax, 0.2 pts. wt. copper sulfate, 0.1 pts. wt. zinc sulfate, 0.2 pts. wt. manganese sulfate, 0.1 pts. wt. ammonium molybdate, 2 pts. wt. bentonite, 0.3 pts. wt. functional bacterial fermentation liquor comprising 1 pt. wt. flour, 0.3 pts. wt. brown sugar, 0.3 pts. wt. microbial inoculum and 8 pts. wt. water, and 0.2 pts. wt. photosynthetic bacterial liquid comprising 0.67 pts. wt. flour, 0.2 pts. wt. brown sugar, 0.2 pts. wt. photosynthetic bacteria and 3 pts. wt. water. An INDEPENDENT CLAIM is also included for preparing the fertilizer, comprising mixing the base mineral powder with other raw materials, adding the obtained mixture into the functional bacterial fermentation liquid, and mixing into ball, (d) hot air drying, (e) sieving, and spraying the photosynthetic bacterial liquid until the photosynthetic bacteria is attached on the granular fertilizer surface at a temperature of less than 60 degrees C, and cooling to obtain the finished product.
