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。
In order to screen out alfalfa varieties suitable for planting in the arid zone of central Ningxia, 28 alfalfa varieties 1-A, 4372, Colra, E3006, M5325 and A8-445 introduced from the United States under irrigation and drought conditions (natural precipitation) MSI MIF 8-IFDs 4-A D2 D3 D3 D4 D5 D6 D7 tP Lt Viago a5335 Dryl N-FRT JN-1 JN-2 JN-3 BLT, SP400, NROLK, and alfalfa (Salix alfalfa) were used to determine the alfalfa germination rate, overwintering rate, botanical traits, growth rate and grass yield. The results showed that varieties D3, D4, E3006, N-FRT and A8-445 could be popularized widely under irrigation conditions. The varieties of 4372, M5325, A8-445 and 1-A could be popularized under the local natural precipitation .
