陇东地区紫花苜蓿品种区域试验研究

A regional test of alfalfa varieties in the Longdong area

2003-2006年,在庆阳市的环县、西峰和宁县等地对15个紫花苜蓿品种进行了区域试验和品质分析。结果表明,甘农1号和苜蓿王是综合性状非常优良的品种,比对照陇东苜蓿丰产稳产、品质突出、适应性广,可在全市大面积推广;金皇后、三得利、巨人、新疆苜蓿、大富豪和皇冠,比对照速生性好、品质优良、丰产稳产性较好,可在当地适宜区种植推广;引种时选用国外良种可迅速提高种草初期的经济效益,选用国内良种可增加苜蓿的抗逆性,延迟高产寿命,提高种草的生态效益。

A regional test and quality analysis of 15 alfalfa varieties was carried out in the Longdong area （Xifeng District, Ningxian County, and Huanxian County of the Qingyang area） during 2003-2006. Gannong No. 1 and Alfaking were varieties with very good characteristics such as higher and more stable yield, better quality and wider adaptability than the control variety （Longdong alfalfa）. The two alfalfa varieties could therefore be planted on a large scale in the whole of the Longdong area. The six varieties, Golden empress, Sanditi, AmeriStand, Xinjiang, Millionaire, and Phabulous, grew faster than the control variety and had better quality and higher, more stable yield, so they could be grown in some suitable local areas. This suggests that selecting superior varieties overseas may rapidly enhance the economic efficiency of developing the crop within a short period, while selecting domestic superior varieties could improve the resistance of alfalfa, prolong the production life, and enhance the ecological benefits of growing the crop.
