Abstract:

In order to examine the yield and quality characterization of 3 alfalfa cultivars in ecotype of middle and lower of Huaihe. Three samples of per variety were collected through systematic sampling method in contiguous planted (200 hm² per variety). The yield and quality of the samples were analyzed. The results showed that the yield and quality traits were affected by years and batches. The varieties only affected the acid detergent fiber and relative feed value. The yield of the first batch was the highest in 2 years, accounting for 38% of the annual yield. Therefore, the quality of the first batch was given priority considered in the selected varieties.

Key words: Medicago sativa, Ecotype of middle and lower of Huaihe, Yield, Quality

摘要：

为研究3个紫花苜蓿品种在淮河中下游地区产量和品质。通过系统抽样方法，在每个品种200 hm²连片种植区各抽取3个样点样品进行产量和品质分析。结果表明：产量和品质性状主要受茬期和年份影响，仅酸性洗涤纤维和相对饲用价值受到品种影响，2年结果都以第一茬产量最高，占总产量的38%，因此在品种选择上，优先考虑第1茬品质性状好的品种。
