To study the production performance and nutritional value of alfalfay,a complete randomized block design was used in this experiment.The results showed that Sitle has the highest dry matter yield up to 16.14 t/hm2 and next comes Golden queen,Sandili,Derby and ACAah,which showed the dry matter yields up to 15.52 t/hm2,15.06 t/hm2,13.99 t/hm2 and 12.54t/hm2,respectively.As cutting times of alfalfa increased,the dry matter yields decreased and significant differences were onserved among five cutting times.The first cutting had the highest yield and the dry matter yield of first three cutting times make up 82.01% of the total yield.Plant height of the top four alfalfa varieties was Sandili,Derby,Golden queen and Sitle,which were more than 60cm.Affinity shows the highest leaf-stem ratio among the fourteen alfalfa varieties,and the following is Multiking,Derby,Golden queen and Millennium.The leaf-stem ratio of the first five varieties was all above 50%.The crude protein content of Multiking was highest.The yield of crude protein of Golden queen was the highest of 2.93 t/hm2 and the following is Derby,Sandili,Sitle and ACAah.
