宁夏灌区半秋眠级苜蓿品种引进筛选研究

Study on Introduction and Screening of Semi-Fall Dormancy Alfalfa Varieties in Ningxia Irrigation Area

摘要: 本文通过引进13个紫花苜蓿品种，以巨能7为对照，在宁夏引黄灌区种植后进行了三年的比较试验，旨在研究半秋眠级紫花苜蓿在本地的生长、产量及营养品质表现，以期获得适宜当地种植的优良苜蓿品种。结果表明，秋眠级在4.9~5.2之间的苜蓿品种劲能5020、SW5909、WL366HQ品种以及秋眠级为6级的探戈品种，其生长性状、产量及营养品质优于其他品种，显著高于对照巨能7，综合当地气候特点及各品种三年的生长表现，苜蓿品种劲能5020、SW5909、WL366HQ、探戈表现最好，适宜作为宁夏引黄灌区推广的首选品种。

Abstract: This paper, by introducing 13 varieties of alfalfa (Medicago sativa L.) which were done a three-year experiment in Yellow River irrigation Ningxia district and were compared to the variety whose name is Power VII, aims to study on performances about their growth, production and nutritional qualities of different varieties of Medicago sativa with different FDR, and expects to gain fine varieties that fit local conditions. The results shows that varieties, whose names are Power 5020, SW5909, and WL366HQ with FDR between 4.9 and 5.2, and the variety whose name is Tango with FDR 6, are significantly higher than Power VII and are superior to others in performances about their growth, production and nutritional qualities. Therefore, local climate and there-year performances considered among all varieties, the varieties whose names are Power 5020, SW5909, WL366HQ and Tango are the pre-eminent varieties of Medicago sativa in Yellow River irrigation Ningxia district due to their excellent performances.
