| 中文摘要: |
| 为了探寻荒漠草原区人工草地适宜的混播组合，利用紫花苜蓿（Medicago sativa L.）分别与蒙古冰草
（Agropyron mongolicum Keng）尧扁穗冰草也A. cristatum （L.）Gaertn页尧沙生冰草（A. desertorum Schult.）和无芒雀麦
（Bromus inermis Leyss）等4 种禾本科牧草以2颐1 的比例混播，比较荒漠草原区不同混播条件下牧草的生长状况和混
播效果。结果表明，试验区草地在建植当年以紫花苜蓿+无芒雀麦组合效果最好，紫花苜蓿+扁穗冰草和紫花苜蓿+沙
生冰草两种组合居中，紫花苜蓿+蒙古冰草组合最差；在荒漠草原中，混播方式可以有效提高草地的生物量，且豆科
和禾本科牧草混播有利于两种牧草的正常生长，是一组很好的混播组合。 |
| 英文摘要: |
| In order to explore the suitable combination of mixed artificial grassland in desert steppe, the Medicago
sativa L. was mixed with Agropyron mongolicum Keng, A. cristatum (L.) Gaertn, A. desertorum Schult and Bromus inermis
Leyss with the proportion of 2颐1 respectively to compare the mixed pasture爷s growth conditions and mixed effects. The
results showed that the combination of M. sativa L. and B. inermis Leyss displayed the best growth and mixed effects,
followed by Medicago sativa L with Agropyron cristatum (L.) Gaertn and M. sativa L. and A.n mongolicum Keng, while M.
sativa L. and A. mongolicum Keng was the worst, during the establishment year. And we can conclued that, in desert
steppe, the way of mixture sowing can significantly improve the grassland biomass. In the meantime, the mixture of legume
and poaceae is a preferadle mixed combination, which is conductive to both kinds of forage self-growth. |
