Abstract: | [Objective] To screen out new high-yield and good-quality alfalfa varieties for multiple cropping after wheat in the irrigation area of Ningxia from Yellow River.[ Method] New high fall-dormancy alfalfa varieties were introduced from North American to conduct the variety comparison test of multiple cropping after wheat in Xixia District of Yinchuan City.[ Result] The average fresh yield and plant height of test alfalfa varieties WL712, WL525HQ, WL656HQ were higher, and the average stem diameter of test alfalfa varieties WL440HQ, WL525HQ, WL656HQ were larger.Taking crude fat and NDF as main indices, all test alfalfa varieties achieved the quality standards of NY/T 1170 -2006.[Conclusion] Multiple cropping of high fall-dormancy alfalfa after wheat in Xixia District of irrigation area of Ningxia from Yellow River was feasible.And the performance of test varieties WL525HQ, WL656HQ and WL712 were ideal. |
