豫西适宜种植富硒谷子品种筛选试验OA

This study aimed to screen the selenium-enriched millet varieties suitable for western Henan,12 common millet varieties in the local area were used as experimental materials(Yugu 18,Henggu 36,Chaogu 58,Yugu 43,Yugu 45,Yugu 35,Jigu 39,Canggu 9,Henggu 11,Henggu 35,Jigu 42 and Zhonggu 989),and 66 g/ha sodium selenite was sprayed on the leaves at the booting stage to determine the yield related factors and grain selenium content of different millet varieties.The results showed that among the 12 millet varieties tested,Henggu 11 had the highest yield,which was 6 438.00 kg/ha.Jigu 42 had the largest number of spikes,which was 42.05 million spikes/ha.Chaogu 58 had the highest thousand grains weight,which was 2.74 g.Henggu 36 had the highest grains weight,which was 19.58 g.Henggu 11 had the highest ratio of winnowed paddy,which was 85.25%.The grain selenium content of Yugu 18,Yugu 35,Yugu 43,Henggu 36 and Chaogu 58 all reached the requirements for selenium-enriched agricultural products.Among them,the grain selenium content of Yugu 18 and Chaogu 58 was relatively high,which was 0.180 mg/kg.The research results provide a reference for the adjustment of agricultural industrial structure and the development of selenium-enriched millet industry in western Henan.
