NOVELTY - A doped modified straw and livestock excrement fertilizer comprises 35-50 pts. wt. corn straw, 50-70 pts. wt. wheat, 25-35 pts. wt. duck manure, 20-30 pts. wt. cow dung, 30-40 pts. wt. sheep manure, 3-4 pts. wt. effective microorganism microbial inoculum, 10-15 pts. wt. urea, 6-10 pts. wt. ammonium chloride, 12-16 pts. wt. potassium nitrate, 15-20 pts. wt. calcium superphosphate, 8-12 pts. wt. potassium humate, 3-5 pts. wt. additive and water.    USE - Doped modified straw and livestock excrement fertilizer.    ADVANTAGE - The fertilizer is rough and fragile, and has good hydrophilic performance.    DETAILED DESCRIPTION - A doped modified straw and livestock excrement fertilizer comprises 35-50 pts. wt. corn straw, 50-70 pts. wt. wheat, 25-35 pts. wt. duck manure, 20-30 pts. wt. cow dung, 30-40 pts. wt. sheep manure, 3-4 pts. wt. effective microorganism microbial inoculum, 10-15 pts. wt. urea, 6-10 pts. wt. ammonium chloride, 12-16 pts. wt. potassium nitrate, 15-20 pts. wt. calcium superphosphate, 8-12 pts. wt. potassium humate, 3-5 pts. wt. additive and water. The additive comprises 1-2 pts. wt. sodium dodecyl sulfate, 6-8 pts. wt. stone powder, 7-10 pts. wt. ethylene acetate, 6-9 pts. wt. alcohol, 2-3 pts. wt. N,N-methylenebisacrylamide and 30 pts. wt. water. The additive is prepared by mixing alcohol and water into reaction kettle, adding ethylene acetate and N,N-methylenebisacrylamide, stirring for 5-10 minutes at speed of 150-200 revolutions/minute (rpm), adding sodium dodecyl sulfate, and stirring for 0.5-1 hour at speed of 250-400 rpm. An INDEPENDENT CLAIM is included for preparation of doped modified straw and livestock excrement fertilizer comprising taking corn straw and wheat, mixing, crushing into crushing machine to and 3-4 cm section, adding water for 2-3 times, adding urea, stirring, dissolving, ammoniation treating at 30-35 degrees C for 12-16 days, filtering to obtain residue, putting into microwave, adjusting microwave power at 210-250 w and microwave radiation function for 6-10 minute, adding duck manure, cow dung and sheep manure, ball mixing, spraying effective microorganism microbial inoculum, adjusting water content to 60%, uniformly mixing, stacking fermenting for 6-10 days, crushing, adding remaining components, uniformly mixing, and controlling water content to 20%.
