从美国和中国引进若干牧草品种,在宁夏盐池干旱风沙区对其进行了适应性、生长状况和生产性能的比较试验,目的是筛选出适合当地种植的牧草品种。结果表明:豆科牧草以宁苜1号、中苜1号和沙打旺的适应性强,产量高,可作为该地区推广种植的优良牧草;草木樨产量最高但越冬率较低,可作为轮作用牧草;禾本科牧草以圆柱披碱草和蒙农杂种冰草适应性较强,且产量较高,可作为当地种植的优良禾草;扁穗冰草和中间冰草存活率较低,适应性及生产性能一般,需采取保护措施提高其存活率才可推广种植;白三叶、金皇后、细茎冰草和高羊茅适应性较差,不宜种植。
A number of forage species were introduced from the United States and China and their adaptability, growth status and performance were compared in arid and sandy areas of Yanchi, Ningxia. The purpose was to screen out forage varieties suitable for local cultivation. The results showed that leguminous forages were better adaptable to Ningmu 1, Zhonglu 1 and Astragalus adsurgens, and could be used as excellent forage for popularization and popularization in this region. The highest yield but lower overwintering rate could be used as the Grass and forage grass; Gramineae forages Elymus and Mengnong hybrid grass better adaptability, and the higher yield, can be used as the local planting of fine grass; Agropyron grass and middle grass survival rate is low, to adapt to Sex and production performance in general, the need to take protective measures to improve its survival rate can promote the planting; white clover, golden queen, thin stem grass and tall fescue less adaptable and should not be planted.
