Abstract: The field experiment to explore the effect of coenzyme Q10 sludge fertilizer on soil and crops,maize as the selected crops,set different dosage of coenzyme Q10 sludge area and single chemical fertilizer area.The results showed that,Sludge fertilizer increased the height of maize,400kg/667m2 rose by an average of 14 cm and 6.5cm,respectively when compared with the blank area and the single chemical fertilizer area.400kg/667m2 of coenzyme Q10 sludge fertilizer rate increased the yield by 10% ~15% than blank area and reached significant difference level,but there was no significant difference with single chemical fertilizer area.The grain protein,fat and starch content of maize increased when applied sludge compared with the blank area,the role of sludge to improve the grain protein content was more obvious compared with single chemical fertilizer.Sludge fertilizer to improve the phosphorus in soil largest,followed by nitrogen, little effect on organic matter and potassium,and no effect on the p H of the soil.Coenzyme Q10 sludge fertilizer had good effect on maize growth,yield formation and quality,also have the effect of improving soil fertility.
