【Abstract】 The objective of this paper was to explore the way of increasing Se content in soybean seed. The experimental result showed that the Se content in soybean seed could be raised remarkably by spraying sterns and leaves of soybean with Na2SeO3 in seed-filling period, and the hightest Se content was 32. 71 times that of control. There were no bad influences on the plant growth and seed yield of soybean after the plant had been sprayed with Na2SeO3.更多还原
