NOVELTY - A high-efficiency drought-resisting composite fertilizer comprises mushroom culture bacteria, rice hull ash, multi-element slow-release fertilizer, excrementum bombycis, polyacrylamide, bean dregs, sodium molybdate, sodium selenite, magnesium sulfate, urea, shrimp shell powder, calcium superphosphate, potassium chloride, quicklime and water. The multi-element slow-release fertilizer includes diatomite, nanocarbon powder, wood sawdust, oil, sodium metasilicate, silane coupling agent KH550, sodium selenite, zinc sulfate, brown sugar, urea and copper sulfate.    USE - High-efficiency drought-resisting composite fertilizer.    ADVANTAGE - The fertilizer improves soil structure, water utilization ratio and soil fertility, thus improving crop yield.    DETAILED DESCRIPTION - A high-efficiency drought-resisting composite fertilizer comprises 120-130 pts. wt. mushroom culture bacteria, 30-34 pts. wt. rice hull ash, 4-5 pts. wt. multi-element slow-release fertilizer, 20-24 pts. wt. excrementum bombycis, 30-34 pts. wt. polyacrylamide, 70-80 pts. wt. bean dregs, 3-4 pts. wt. sodium molybdate, 2-3 pts. wt. sodium selenite, 10-12 pts. wt. magnesium sulfate, 20-25 pts. wt. urea, 12-14 pts. wt. shrimp shell powder, 30-35 pts. wt. calcium superphosphate, 10-12 pts. wt. potassium chloride, 20-24 pts. wt. quicklime and balance water. The multi-element slow-release fertilizer comprises 40-45 pts. wt. diatomite, 1-2 pts. wt. nanocarbon powder, 32-34 pts. wt. wood sawdust, 4-6 pts. wt. oil, 2-3 pts. wt. sodium metasilicate, 2-3 pts. wt. silane coupling agent KH550, 1-2 pts. wt. sodium selenite, 1-2 pts. wt. zinc sulfate, 1-2 pts. wt. brown sugar, 15-16 pts. wt. urea, 1-2 pts. wt. copper sulfate, 10-12 pts. wt. potassium chloride, 3-4 pts. wt. chitosan, 1-2 pts. wt. chlorinated paraffin, 2-3 pts. wt. Eucalyptus oil and balance water, prepared by heating to dissolve sodium metasilicate in water, adding diatomite, nanocarbon powder, wood sawdust, sodium selenite, zinc sulfate, brown sugar, urea, copper sulfate, potassium chloride and silane coupling agent KH550, uniformly stirring to form slurry, adding remaining components, stirring for 40-50 minutes at speed of 1200-1500 revolutions/minute and condensing into particles. An INDEPENDENT CLAIM is included for preparation of high-efficiency drought-resisting composite fertilizer comprising heating urea to melt, adding sodium molybdate, sodium selenite and magnesium sulfate, cooling, granulating, adding polyacrylamide and water, stirring, adding remaining raw materials, uniformly mixing, granulating and drying.
