NOVELTY - Straw mesophyll embedded microbial fertilizer comprises 20-30 pts. wt. rice straw, 40-50 pts. wt. humilis straw, 15-25 pts. wt. dried Artemisia leaves, 80-120 pts. wt. sodium hydroxide solution, 5-7 pts. wt. beneficial soil microorganisms, 10-15 pts. wt. potassium chloride, 12-17 pts. wt. ammonium bicarbonate, 12-15 pts. wt. ammonium monohydrogen phosphate, 8-12 pts. wt. rock phosphate, 4-6 pts. wt. zinc sulfate, 4-5 pts. wt. binding agent and water (specific amount). The binding agent comprises e.g. 1,4-butanediol, styrene, ethylene glycol dimethacrylate, ethanol and water.    USE - The microbial fertilizer is useful for embedding microbial strains.    ADVANTAGE - The microbial fertilizer: has good activated coal absorbing function; provides the nutrients of microbial life and soil organic colloid components; and prevents moisture loss.    DETAILED DESCRIPTION - Straw mesophyll embedded microbial fertilizer comprises 20-30 pts. wt. rice straw, 40-50 pts. wt. humilis straw, 15-25 pts. wt. dried Artemisia leaves, 80-120 pts. wt. sodium hydroxide solution with concentration of 3-6%, 5-7 pts. wt. beneficial soil microorganisms, 10-15 pts. wt. potassium chloride, 12-17 pts. wt. ammonium bicarbonate, 12-15 pts. wt. ammonium monohydrogen phosphate, 8-12 pts. wt. rock phosphate, 4-6 pts. wt. zinc sulfate, 4-5 pts. wt. binding agent and water (specific amount). The binding agent comprises 1-3 pts. wt. 1,4-butanediol, 8-12 pts. wt. styrene, 1-3 pts. wt. ethylene glycol dimethacrylate, 5-8 pts. wt. ethanol, 2-4 pts. wt. sodium dodecyl sulfate, 10-12 pts. wt. tea tree oil, 15-20 pts. wt. zinc gluconate, and water (specific amount). The binding agent prepared by (i) taking ethanol in a stirrer, adding 8-10 times of water, diluting, stirring at a speed of 300-500 rotations/minute (rpm), adding styrene and ethylene glycol dimethylacrylate, stirring for 10-15 minutes, and carrying out polymerization, (ii) taking sodium dodecyl sulfate in a reaction tank, mixing with the tea tree oil and zinc gluconate, adding 2-3 times of water, and stirring for 20-30 minutes to obtain emulsion, and (iii) mixing the resulting products obtained in step (i) and (ii), adding equal amount of 1,4-butanediol, and stirring at the speed of 200-400 rpm for 30-50 minutes, and complexing. An INDEPENDENT CLAIM is also included for preparing the microbial fertilizer, comprising (a) crushing the rice straw, humilis straw and dry dried Artemisia leaves, adding 3-6% sodium hydroxide solution to soaking at 30 degrees C for 8-10 hours, ball-milling for 10-15 minutes to obtain mixed slurry, centrifuging, removing supernatant, taking lower layer of precipitate and partially dividing the bottom layer grain and flocculent surface layer, (b) taking the bottom layer grain obtained in the step (a), drying to obtain powder, placing in a carbonizing furnace under sealed condition, heating the carbonizing furnace to 600-700 degrees C for 5-8 hours, and cooling to room temperature to obtain carbonized product, (c) mixing potassium chloride, ammonium bicarbonate, ammonium monohydrogen phosphate, rock phosphate and zinc sulfate, crushing into powder, adding carbonized product obtained in step (b), rolling and stirring for 15-25 minutes and uniformly mixing, and (d) adding soil beneficial microorganisms into the flocculent portion obtained in the step (a), adding equal amount of water, uniformly stirring, then carrying out centrifugation at speed of 2000 rpm for 20 minutes for embedding, drying the bottom layer precipitate, mixing the binding agent, product obtained in step (c) and other remaining components, finally adjusting water content to 35%, and granulating into particle size of 4-5 mm using a disc granulator.
