| Abstract: | 【Objective】The present experiment was conducted to select elite spring wheat varieties with strong ability of selenium absorption and accumulation in selenium-enriched area of Qinghai Province. 【Method】Field experiment was carried out with split plot design for six treatments viz.， application of Zn fertilizer rate of 210 g/ha， selenium （Se） fertilizer rate of 3626 mg/ha and no fertilizer （control） on two spring wheat cultivars Qingchun 38 and Abo， respectively. The effects of spraying Se and Zn fertilizer on yield， Se absorption and accumulation characteristics of two spring wheat cultivars were studied. 【Result】Compared with control， the yield of Qingchun 38 increased by 21.66%， ranked the first by spraying Zn fertilizer， followed by Abo spraying Se fertilizer， with the increment of 20.19%. For the treatments spraying Zn fertilizer， Se concentration in grain of Qingchun 38 increased by 50.70%， and that of Abo increased by 61.73%. For the treatments spraying Se fertilizer， Se concentration in grain of Qingchun 38 soared by 81.69% and that of Abo soared by 90.12%. Se absorption and accumulation in grain of Abo were both higher than those of Qingchun 38 under the same fertilizer treatments. Se concentrations in different organs after harvest followed the trend：root > leaf > grain > stem. Se absorption and accumulation followed the trend: grain > stem > leaf > root. 【Conclusion】Spraying Zn fertilizer and Se fertilizer could boost the yields of various spring wheat varieties. Abo， spring wheat showed better absorption and accumulation ability than Qingchun 38， which was desirable for extension in selenium-enriched area of Qinghai Province. |
