摘要
为了筛选出适宜于北疆种植的高产优质饲用高丹草材料,在呼图壁旱生牧草种子基地采用随机区组试验设计,5份饲用高丹草材料开展区域适应性评价。结果表明:5份材料GS5拔节期最早,出苗率最高,株高适中,干草总产量也为所有材料的最大值;GS6株高最高,出苗率低,但随着季节及刈割茬次,干草产量较大,GS6再生性好,生长速度快。综合对比,GS5、GS6这两份材料,综合选择适宜北疆地区种植的高丹草材料。
In order to screen high-yield and high-quality forage sorghum hybrid sudangrass materials suitable for planting in the plain desert area of northern Xinjiang,a randomized block design was used to evaluate the regional adaptability of five sorghum hybrid sudangrass materials in Hutubi dry forage seed base.The results showed that,GS5 had the earliest jointing stage,the highest seedling emergence rate,moderate plant height and the highest hay yield;GS6 had the highest plant height and low seedling emergence rate,but with the seasons and mowing,the hay yield was relatively high,indicating that GS6 had good regeneration and rapid growth.By comprehensive comparison,GS5 and gs6 can be used as further research objects to select the materials suitable for planting in Northern Xinjiang.
