| Abstract: | In order to obtain the best mixed sowing mode of two alfalfa varieties in the Yellow River diversion irrigation area in Ningxia,the experiment adopted a single-factor randomized block design to investigate the effects of mixed seeding of alfalfa varieties ‘Sanditi’ and ‘Magna Graze Ⅶ’ in 1∶1,1∶2 and 1∶3 row ratios and single seeding of ‘Sanditi’ and ‘Magna Graze Ⅶ’ on the production performance and quality of grassland under drip irrigation. The principal component analysis method (Principal Component Analysis,PCA) was used for comprehensive evaluation. The results showed that there was no significant difference in plant height,neutral washing fiber,acid washing fiber and crude protein content in each treatment mode;The four crops average number of first-order branches,stem diameter,crude fat and total output of hay were higher than those of other sowing modes in the mixed-planting mode of ‘Sanditi ’ and ‘Magna Graze Ⅶ ’,Its hay yield was as high as 16.15 t·hm-2,which was 11.16% and 9.47% higher than the unicast of ‘Sanditi’ and ‘Magna Graze Ⅶ’ respectively;The ratio of stem-leaf and crude ash content of mixed sowing of ‘Sanditi’ and ‘Magna Graze Ⅶ’ at a row ratio of 1∶1 was relatively lowest,and the relative feeding value of mixed sowing of 1∶3 row ratio was the highest,which was 184.97,significantly higher than that of ‘Magna Graze Ⅶ’ unicast (P<0.05). According to PCA analysis, ‘Sanditi’ and ‘Magna Graze Ⅶ’ in 1∶1 row ratio mixed sowing had the best comprehensive characters,which could be popularized and applied in drip irrigation in the Yellow River diversion irrigation area in Ningxia. |
