| 摘 要： | 以内蒙沙芦草为原始群体,采用单株-混合选择法,经过10多年选育获得一个性状表现一致、生产性能良好的新品系。新品系株丛较高大、整齐,一般株高为97~116cm,最高可达122cm,比原始群体平均增高19cm;分蘖力强,生活第二年平均单株丛分蘖数为142个,最多可达160个,比原始群体平均增多40个;牧草及种子产量分别比原始群体提高28.2%和37.7%,而且叶量大,种熟期一致。该品系适宜在我国北方年降水量200~400mm的干旱、半干旱地区种植,可用于放牧地的建植、改良及退化沙化草地植被恢复。

| Abstract: | A new strain selected from Agropyron mongolicum Keng.cv.Neimeng had been bred by individual-mass selection for more than 10 years.The plants of new strain were taller than original material by 19cm;the tiller number per plant was more than that of the original;the hay yield and seed yield were increased by 28.2% and 37.7 % respectively compared with the original;It is suitable to grow in arid and semiarid area of the northern China,and also a excellent seeding material for the grazing-land planting and improvement,and degraded pasture restoration. |
