| 摘 要： | 金花菜(Medicago polymorpha)是苜蓿属植物,可用作绿肥、饲料、蔬菜。为确定金花菜在扬中市的最适播种期,进一步提高该地区的金花菜产量,以淮扬金花菜和温岭金花菜为材料,研究了不同播种期对金花菜的发芽率、出苗率、成活率、分枝数和产量的影响。结果表明:金花菜种子萌发的最适温度为25℃,9月中下旬播种的淮扬金花菜和温岭金花菜出苗率、成活率、分枝数、产量等皆高于8月份和10月初播种的。淮扬金花菜在播种期为9月29日时产量最高,为3 164.7kg·hm~(-2),温岭金花菜播种期为9月19日时产量最高,为1 969.20kg·hm~(-2),在产量上表现为淮扬金花菜优于温岭金花菜,因此在江苏扬中地区9月中下旬播种淮扬金花菜可实现高产。

| Abstract: | Medicago polymorpha can be used as green manure, fodder, and vegetable.To improve the production of M.polymorpha in Yangzhong region, experiments were carried out using Huaiyang and Wenling cultivars to study the effect of different sowing dates on the germination and survival rates, number of branches, and production of plants.The results showed that the most suitable temperature for germination of M.polymorpha seeds was 25 ℃.The Huaiyang and Wenling cultivars planted in mid or late September showed, seedling emergence, survival rates, the number of branches, and yield that were all higher than those of cultivars planted in August and early October.The Huaiyang and Wenling cultivars showed the highest yields of 3 164.7 and 1 969.20 kg·ha-1 with sowing dates of September 29th and 19th, respectively.Furthermore, the Huaiyang cultivar showed a higher yield than that of the Wenling cultivar.Therefore, in the Yangzhong area, sowing the Huaiyang cultivar in mid to late September would enable farmers to obtain a high yield. |
