宁夏中部干旱带苜蓿品种引进筛选试验

A test in introduction and screening of alfalfa varieties in the central arid areas of Ningxia

为了筛选出适合宁夏中部干旱带种植的苜蓿品种,试验分别在灌溉和干旱条件(自然降水)下对从美国引进的28个苜蓿品种1-A、4372、Colra、E3006、M5325、A8-445、MSI、MIF、8-IFDs、4-A、D2、D3、D4、D5、D6、D7、tP、Lt、Viago、a5335、Dryl、N-FRT、JN-1、JN-2、JN-3、BLT、SP400、NROLK,以及中苜一号和本地苜蓿(盐池苜蓿)进行了苜蓿发芽率、越冬率、植物学性状、生长速度及产草量等指标的测定。结果表明:D3、D4、E3006、N-FRT、A8-445等品种适宜在灌溉条件下大面积推广种植;4372、M5325、A8-445、1-A等品种可在本地自然降水条件下推广种植。

To screen out suitable alfalfa varieties to plant in central arid areas of Ningxia, 28 alfalfa varieties from American,including（ 1 - A, 4372 ,Colra,E3006 ,M5325 ,AS -445 ,MSI,MIF,8 -IFDs,4 -A,D2,D3 ,D4,D5 ,D6,D7,tP,Lt,Viago,a5335 ,Dryl, N - FRT,JN - 1 ,JN - 2 ,JN -3 ,BLT,SP400 ,NROLK） ,Zhongmu No. I and the local alfalfa（ Yancbi alfalfa） , were used as experimental materials, and then the germination rate, winter survival rate, botanical character, growth rate and forage production were determined under supplementary irrigation and natural rainfall, respectively. The results showed that the alfalfa varieties, including D3, IM, E3006, N -FRT and A8 -445, were the most suitable varieties, which could be planted widely under irrigated condition. The varieties of 4372, M5325, A8 -445 and 1 -A could be planted widely under natural rainfall.
