    Adaptability Evaluation of 18 Cowpea Varieties in Early Spring Facility Cultivation in Fuzhou Region

    • 摘要: 为筛选适合福州地区早春设施栽培的耐寒高产豇豆品种,以晓富宝为对照品种,对18个豇豆品种开展农艺性状和产量的比较试验。结果表明:长龙开花期65 d、生长势中等、外叶绿色、第1花序平均节位3.5节、始收期78 d、花色紫色、果荚深绿色、无鼓粒、无鼠尾、平均果荚长69.0 cm、平均果径0.85 cm、叶斑病抗性为感病、锈病抗性为抗病,产量为41 062.80 kg·hm−2,比对照增产27.58%;翠豇开花期67 d、生长势中等、外叶绿色、第1花序平均节位3.5节、始收期78 d、花色紫色、果荚绿色、轻度鼓粒、无鼠尾、平均果荚长71.0 cm、平均果径0.73 cm、叶斑病抗性为中等抗病、锈病抗性为感病,产量为37 289·70 kg·hm−2,比对照增产15.86%;青豇2号和青条四季绿产量与翠豇相当,与长龙产量相差较大,不建议使用。在福州地区早春设施栽培中,喜欢深绿色果荚品种的推荐使用长龙,喜欢绿色果荚品种的推荐使用翠豇。

       

      Abstract: In order to screen the cold-resistant and high-yielding cowpea varieties suitable for early spring facility cultivation in Fuzhou, by taking Xiaofubao as the control variety, the comparative experiment was carried out on the agronomic traits and yield of 18 cowpea varieties. The results showed that: Changlong variety exhibited the following characteristics: flowering at 65 days, moderate growth vigor, green outer leaves, an average node position of 3.5 for the first inflorescence, initial harvest at 78 days, purple flower color, dark green pods, no swollen seeds, no rat-tailing, average pod length of 69.0 cm, average pod diameter of 0.85 cm, susceptible to leaf spot disease, resistant to rust disease, etc. Its yield was 41062.80 kg·hm−2, which was 27.58% higher than that of the control. Cuijiang exhibited a flowering period of 67 days, moderate growth vigor, green outer leaves, an average node position of 3.5 for the first inflorescence, a harvest onset period of 78 days, purple flowers, green pods, slight pod swelling, no rat tail, average pod length of 71.0 cm, average pod diameter of 0.73 cm, moderate resistance to leaf spot disease, and susceptibility to rust disease. Its yield was 37289.70 kg·hm−2, which was 15.86% higher than that of the control. The yield of Qingjiang No.2 and Qingtiao Sijilv was equivalent to that of Cuijiang, and the yield was quite different from that of Changlong, so they were not recommended. For the early spring facility cultivation in Fuzhou area, Changlong was recommended for the growers preferring dark-green pods, while Cuijiang was recommended for those favoring green pods.
