摘 要: 2002-2003年在内蒙古正蓝旗草籽繁殖场进行了田间试验,旨在探索当地自然气候和生产条件下,蒙古冰草种子田的适宜播种技术。经播种行距、种肥量和播种量三因子三位级正交试验结果表明:条播行距是影响蒙农1号蒙古冰草种子产量和品质的主要因子,种肥量和播种量为次要因子。建植蒙农1号蒙古冰草种子田时,条播的最适行距为38cm;用撒可富作种肥的适宜施用量为157.8kg/hm^2;播种量13.3-52.6kg/hm^2为宜。 An orthogonal test with row spacing, seed fertilizing rate and seeding rate was carried out in Zhenglanqi of Inner Mongolia from 2002 - 2003. It was found out that the row spacing was the main factor affecting seed yield and quality of Agropyron mongolicum Keng. cv. Mengnong NO. 1, seed fertilizing rate and seeding rate were the second factors; the optimal row spacing for seed production of Agropyron mongolicum Keng. cv. Mengnong NO. 1 was 38 cm, the optimal seed fertilizing rate of Sakefu, a fertilizer, was 157.8 kg/ha, and the optimal seeding rate was 13.3 - 52.6 kg/ha.
