Example Embodiment
[0015] Example one:
[0016] A highly efficient concentrated selenium-enriching agent absorbed by plant leaves, containing sodium selenite, glutamic acid, arginine, aspartic acid, brassinolide and gibberellin (composed in a ratio of 1:1) And urea and phosphate, wherein the concentration of selenium element by mass percentage is 20%-25%M / V; the concentration of the absorption promoting agent is 0.1%-1%M / V by mass percentage . Efficient and safe concentrated selenium-enriching agent is sprayed on crop corn after being diluted with water 1:500 before use.
Example Embodiment
