Abstract: The effects of basal Se fertilizers (570~1143 g穐m-2 for Na2SeO3?5H2O) on production characteristics of naked oats (Avena nuda) were investigated on yellow river beach in order to find new approaches of enhancing production levels of naked oats and enriching fine forage resources for local animal industry. Results showed that Se fertilizers had optimal effects when application rate was 765~954 g穐m-2. Fresh to dry ratio (F/D ratio) of naked oat was reduced by 6.69%. Stem to leaf ratio (S/L ratio) of naked oat was increased by 10.01% and tillering number was enhanced by 12.50% (P<0.05). Forage yield was increased by 8.22% (P<0.05) in flowering stage. In addition, Se fertilizer could increase thousand- grain weights significantly, but not significantly affect the grain yield of naked oats. It is effective and feasible to raise productivities of naked oat by applying Se basal fertilizers.

摘要： 在河南省黄河滩区种植莜麦(Avena nuda)的地段上播前基施硒肥,研究硒肥(Na2SeO3·5H2O)用量在570~1143 g·hm-2时,对莜麦生产特点和生产性能的影响,探索提高莜麦生产水平的新途径,进一步丰富河南优质饲草资源。结果表明:对莜麦生产适宜的硒肥基施量为765~954 g·hm-2,基施硒肥能使莜麦的鲜干比平均降低6.69%(P<0.05),茎叶比平均提高10.01%(P<0.05),分蘖数平均提高12.50%(P<0.05),扬花期干草产量平均提高8.22%(P<0.05);另外,硒肥还能显著提高种子的千粒重,但不能提高莜麦果实产量。 因此,合理基施硒肥是提高莜麦生产水平的可行而有效的手段,为莜麦在滩区的优质高产提供技术保证。
