不同播期和密度对大麦新品种“花11”在皖北地区产量的影响

Effects of Sowing Date and Seeding Density on Yield in Barley New Variety of "Flower 11" in North of Anhui

为给皖北及邻近地区引种大麦新品种"花11"提供依据,研究了不同播期和不同播种密度对产量的影响。结果表明:"花11"品种在皖北地区的播种期为10月下旬至11月上中旬,播种密度为22万/667m2较为合适,其中播种期对产量的影响比较小,而播种量对产量的影响比较大。因此设置更多的播期、适当再提高播种密度可能有助于找到更适宜的播期和密度来提高"花11"在皖北地区的产量。

To provide theoretical basis, a field trail was carried out to investigate the effects of different sowing dates and different seeding densities on yield in barley variety of ＂Flower 11＂ in north of Anhui. The results showed that the sowing dates during in late October to mid-November and the seeding density of 22000 plants per 667 m^2 were more appropriate, in which the impact of sowing date on yield was smaller, while the seeding density on yield was larger. Therefore, setting up more sowing dates and increasing seeding density may help to find a more suitable sowing date and density to increase the yield of ＂Flower 11＂ in Northern Anhui.
