科尔沁草原是典型的农牧交错地区，长期以来，由于不合理利用草地资源造成该区生态环境严重恶化，农牧业生产受到严重影响[1]。建立高产优质的人工草地是解决我国高寒地区草畜供求季节不平衡的矛盾，促进草地畜牧业持续发展的关键措施之一[ 2]。无芒雀麦和紫花苜蓿都是营养价值高、适口性好、抗寒抗旱能力强的多年生牧草。将这两种牧草混播不仅能提高牧草产量和品质，延长草地使用年限，还能改善牧草的营养，提高牧草的适口性，有利于调制和青贮[3]。

3撒播时，引进种在播种密度为549粒·m~(-2)处理下单位面积出苗率最高，分蘖数最多，鲜重最大，单株最高，种子产量最大；生长速度在播种密度为412粒·m~(-2)处理下生长最快，密度为549粒·m~(-2)处理下稍次之，结合方差分析可以初步确定它在撒播时的播种密度为549粒·m~(-2)；(4)条播时，在行距为25cm、播种密度为412粒·m~(-2)处理下单位面积分蘖数最多，鲜重最大，单株最高，生长速度最快；种子产量在行距为15cm、播种密度为824粒·m~(-2)处理下最大，在行距为25cm、密度412粒·m~(-2)处理下次之；结合方差分析，就3种规格的行距来说，引进美国无芒雀麦条播时的行距为25cm，播种密度为412粒·m~(-2)；就这两种播种方式来说，应该选择撒播。

Plant traits were categorized to three classes: the first class traits were dominated by major gene with little genetic effect of polygene, including days from sowing to flowering, days from sowing to boll opening, lint percent, days from squaring to flowering, days from flowering to boll opening and plant bolls.
