Abstract: In order to understand the effect and best use of selenium enriched power to spring wheat, six locations in Bayannur were selected for random plot trials in different locations. The results showed that spraying 2 times of selenium enriched fertilizer increased 605.25 kg/hm^2 and increased by 8.8% compared with the control CK2,and 1 time selenium enriched fertilizer increased the yield compared with the control CK1 ,the yield increased by 350.25kg and increased range to 5.13%;Spraying selenium-rich fertilizer can significantly increase the number of grains per spike, spike weight, 1000-grain weight and bulk density.
