摘要
为了提高土地利用率、种植效益,为本地区提供优质饲草,本研究以多年筛选的适宜河套灌区种植的6个大麦品种为参试材料,通过随机区组试验,综合分析各品种的株高、草产量和营养指标,筛选出适宜河套灌区春闲田种植的饲草大麦品种。结果得出:参试的6个品种中,12PJ-051的干草产量最高,为813.37kg/亩,粗蛋白含量11.8%,后茬育苗向日葵JK601产量为265.6kg/亩,并且可保证正常成熟。因此,12PJ-051作为优质饲草适宜在河套灌区春闲田种植。
In order to improve the land use rate/the planting efficiency and provide high quality forage for this area,six barley varieties were selected as the test materials to be suitable for planting in Hetao Irrigation Area.By the experimental of randomized blocks,the suitable forage barley varieties were selected based on the comprehensive analysis of plant height,grass yield and nutrient indices.The results showed that the six varieties tested,12PJ-051 had the highest hay yield,813.37kg/667.7m2,11.8%crude protein content,265.6kg/667.7m2 yield of sunflower JK601 for subsequent cropping,and could ensure normal maturity.Therefore,12PJ-051 as high quality forage is suitable for planting in spring idle farmland in Hetao irrigation district.
