Abstract Effect of new plant growth regulator compound sodium nitrophenolate，DA-6 on ginger （Zingiber offcinale Rosc.）growth，yield and quality was studied in field．The results showed that compound sodium nitrophenolate，DA-6 could significantly promote the growth of ginger，but only the roots grew better than the control in early growth period．With the growth of ginger，the fresh weight of various plant organs of ginger applied compound sodium nitrophenolate and DA-6 were notably higher than the control．When harvesting，compared with the control，the plant height of ginger applied compound sodium nitrophenolate，DA-6 was increased by 11.59% and 14.02%，the number of branches increased by 24.59% and 28.69%，yield increased by 18.53% and 22.30%，respectively. But there was no significant difference between the treatments of compound sodium nitrophenolate and DA-6．In addition，the compound sodium nitrophenolate，DA-6 have also increased the contents of rhizome starch，soluble protein and amino acid of ginger by different degrees.
