| Abstract: | The productivity performance of 10 alfalfa cultivars in acid soil was evaluated by using a synthetic evaluation model based on five main indexes of alfalfa including plant height,number of tiller,shoot dry weight,stem-leaf ratio and root dry weight.The results showed that the cultivar Sanditi not only earned the highest score,but also had relatively good comprehensive productivity performance,which indicated that it was suitable for spreading and planting in acid soil of Southern China. |
