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。
With the initial population of A. lucidum, single-hybrid selection method was used to obtain a new line with consistent performance and good performance after more than 10 years breeding. The lines of the new lines are tall and neat. The average plant height is 97cm to 116cm, up to 122cm, an average of 19cm higher than that of the original population. The tillering ability is strong, and the average number of tillers per plant in the second year of life is 142, up to a maximum of 160, an average of 40 more than the original population; pasture and seed yield increased 28.2% and 37.7%, respectively, than the original population, and the leaf amount is large, the same maturity. The strain is suitable for planting in arid and semi-arid areas with an annual precipitation of 200-400 mm in northern China. It can be used for the construction of grazing land, improvement and vegetation restoration of degraded sandy grassland.
