禾本科牧草在典型草原区的适应性研究

Adaptability of Grasses in Distinct Steppe Region

2001-2003年在内蒙古锡林郭勒盟太仆寺旗通过小区试验,对来自美国、加拿大和中国的21份禾本科牧草进行了物候期、产草量和种子产量的评价和适应性研究。结果表明,来自美国和中国的6份材料不仅适应性较强,而且产草量和种子产量也相对较高,可作为该地区人工草地建设和天然草场改良的优良种质材料。

This experiment was carried out in Taipusi Banner of Inner Mongolia from 2001 to 2003. Totally 21 grasses introduced from America, Canada and originated in China were evaluated with their phenophase, hay yield and seed yield. The result showed that six among them had relatively strong adaptability as well as higher yield, so could be used as germplasm material for artificial grassland establishment and natural grassland improvement in this region.
