摘要
叶面喷施硒肥可以明显提高糜子籽粒中硒含量，但不同糜子品种富硒能力具有一定差异。60 g/hm2处理的糜子籽粒中硒含量为0.04~0.32 mg/kg，比对照平均增加了13.5倍；120 g/hm2处理的糜子籽粒中硒含量为0.07~0.46 mg/kg，比对照平均增加了19.4倍；180 g/hm2处理的糜子籽粒中硒含量为0.13~0.57 mg/kg，比对照平均增加了21.8倍；叶面喷施硒肥对糜子产量的影响不明显，对相同处理的不同糜子品种的产量有影响；叶面喷施硒肥能使多数糜子品种籽粒的蛋白质含量略有增加。
Spraying Se fertilizer could obviously improve the Se content of broomcorn millet grain,but Se rich ability of different broomcorn millet varieties was different. The Se content of broomcorn millet grain was 0.04~0.32 mg/kg when Se fertilizer was 60 g/hm2,which was increased of 13.5 times than control. The Se content of broomcorn millet grain reached 0.07~0.46 mg/kg when Se fertilizer was 120 g/hm2,which was increased of 19.4 times than control. The Se content of millet grain reached 0.13~0.57 mg/kg when Se fertilizer was 180 g/hm2,which was increased of 21.8 times than control. The influence of selenium fertilizer on broomcorn millet yield was not obvious,but the production of different broomcorn millet varieties was different. The protein content of most broomcorn millet varieties increased slightly by applying Se fertilizer.
