Abstract: To investigate application effect of dihydroporphyrin iron soluble powder on ginger cultivation, 0.01% brassinolide emulsion was used as a control agent, and 0.02% dihydroporphyrin iron soluble powder was selected for field experiments on ginger．Research results indicated that 0.02% dihydroporphyrin iron soluble powder not only promoted some growth traits of ginger, but also increased ginger yield without causing any drug damage, and has good safety．The diluted 5000 times treatment showed the most significant improvement and yield increase in ginger plant height, stem diameter, number of branches, leaf width, and leaf length, with increases of 9.96%, 9.92%, 16.81%, 8.42%, 8.47%, and 14.23%, respectively．It was indicating that 0.02% dihydroporphyrin iron soluble powder could promote ginger growth and increase ginger yield, laying a foundation for its further promotion and application in ginger cultivation．
