TECHNOLOGY FOCUS - AGRICULTURE - Preferred Component: The bacterial fertilizer can be biological bacterial fertilizer obtained from azotobacteria, potassium bacteria, phosphorus bacteria, bacillus, microzyme, Rhizobium and ray fungi. The fertilizer comprises (pts.wt.) high molecular weight acrylic acid polymer (1-1.5), compound biological bacteria fertilizer (1.3), decomposed chicken manure (4-15), grass carbon (4-5), biogas residues (10), urea (20-30), monoammonium phosphate (10-15), potassium chloride (20-25), zinc (0.5-0.7), manganese (0.5-0.7), light-burnt magnesia (6-8), and copper (0.5). The fertilizer is prepared by premixing compound biological bacteria fertilizer with grass carbon, adding trace elements, adding remaining grass carbon, ammonium phosphate, decomposed chicken manure, biogas residues, urea, potassium chloride, magnesia and acrylic acid polymer, mixing for 5-7 minutes, granulating, controlling moisture content to 8-10%, squeezing into granules, screening, and packaging.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The inorganic nitrogen, phosphorus and potassium are urea powder having 46% nitrogen content; monoammonium phosphate powder having greater than or equal to 44% phosphorus content; and potassium chloride powder having 20-60% potassium content, respectively. The trace elements comprise boron, zinc, manganese, copper, molybdenum and/or magnesium.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The organic matter comprises sterilized herbaceous grass carbon containing organic matter (52%) and humus ( greater than or equal to 30%); mixture of wet fowl manure, pig manure and straw bran; and biogas residues fermented, air-dried and crushed in methane tank, where the biogas residues contains organic matter ( greater than or equal to 49%), and organic nitrogen, phosphorus and potassium ( greater than or equal to 10).    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The sustained release agent with millipores can be high molecular weight acrylic acid polymer. ACTIVITY - Fertilizer.
