豫南金花菜品种比较试验

为了筛选适宜豫南种植的高产、优质金花菜品种,对息州金花菜、楚雄南苜蓿、淮扬金花菜3个金花菜品种进行了引种品比试验。通过生育期观测、农艺性状测定及营养成分分析对其进行品种比较。结果表明,淮扬金花菜鲜草产量、干草产量及粗蛋白含量均为最高,分别为42.44 t/hm²、8.94 t/hm²、17.29%,与其他两个品种相比差异均显著(P<0.05)。由以上结果可以得出,淮扬金花菜高产、质优,建议在豫南推广种植。

A Comparative Trial of Medicago polymorpha Varieties in Southern Henan Province

In order to screen the high-yield and excellent-quality burclover (Medicago polymorpha) varieties suitable for Southern Henan Province, a comparative trial of three introduced burclover varieties of Xizhou, Chuxiong and Huaiyang was conducted. The growth period of the three tested varieties was observed, and their agronomic characteristics and nutritional components were determined. The results showed that the highest fresh grass yield, hay yield and crude protein content were simultaneously observed in the burclover variety of Huaiyang, which were 42. 44 t/hm², 8. 94 t/hm² and 17. 29%, respectively, and were all significantly (P<0. 05) higher than their counterparts of the other two burclover varieties. In conclusion, the burclover variety of Huaiyang had better performance in grass yield and quality in Southern Henan Province, indicating its good suitability and popularizing value in this region.
