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 5 000 times treatment showed the most significant im-provement 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.
