| 摘要: |
| 【目的】筛选适宜宁夏北部引黄灌区种植的高产苜蓿品种。【方法】2012-2014年采用小区试验对8个紫花苜蓿品种进行了连续3年的产量性能研究。【结果】8个苜蓿品种在银川地区都能安全越冬，皇冠生产性能最强，年平均干草产量为19.64 t/hm2，且鲜干比和茎叶比相对较大；三得利、WL343HQ、金皇后、柏拉图、阿尔冈金生产性能较强，3年平均干草产量为17.01～18.14 t/hm2；中苜1号和固原紫花年平均干草产量较低，仅为14.66和11.35 t/hm2。刈割茬次显著影响苜蓿的干草产量、鲜草产量、株高，随刈割茬次的增加3个指标明显下降，刈割茬次对鲜干比和茎叶比的影响相对较小。所测的5个指标中，除鲜干比与其他指标不存在显著相关性以外，其余各指标间均存在极显著相关性。【结论】皇冠在宁夏引黄灌区生产表现最好，适合大面积推广；中苜1号和固原紫花表现相对较差，不适合在宁夏引黄灌区推广种植。 |

| Abstract: |
| 【Objective】The purpose of this study was to select alfalfa varieties suitable for planting in the Yellow River irrigation region of Ningxia.【Method】Based on field experiments from 2012 to 2014,yield performance of 8 alfalfa cultivars was evaluated,and those suitable for the irrigation region in north Ningxia were selected.【Result】All 8 alfalfa varieties could overwinter safely in Yinchuan.The yield of Phabulous was the highest of 19.64 t/hm2 in three years,and its fresh/dry ratio and stem/leaf ratio were large.The average hay yields of Sanditi,WL343HQ,Golden Empress,Pltao,and Algonguin were 17.01-18.14 t/hm2,while the hay yields of Zhongmu No.1 and Guyuanzihua were as low as 14.66 t/hm2 and 11.35 t/hm2.Stubble times significantly affected the alfalfa dry matter yield,fresh matter yield and plant height,and they decreased significantly with the increase of stubble time.The influence on fresh/dry ratio and stem/leaf ratio was minor.Except for fresh/dry ratio,all other indexes had significant correlations between each other.【Conclusion】Production performance of Phabulous was best among the 8 alfalfa varieties,and it is suitable for planting in the Yellow River irrigation region of Ningxia.Zhongmu No.1 and Guyuanzihua were not suitable. |
