3个豇豆品种秋延栽培适应性初步研究

探讨奇多、奇宝2个豇豆品种在本地区秋延栽培的适应性，试验以之豇28-2为参考对照，研究比较3个豇豆品种的生育期、产量，以及始花节位与产量之间的相关性。结果表明：在秋延栽培过程中，奇宝为中晚熟品种，产量低，不适宜作为秋延栽培的推广品种；之豇28-2和奇多为早熟品种，产量较高，可作为当地秋延栽培的主推品种。另外，研究结果还表明奇宝、之豇28-2与奇多3个豇豆品种的产量与始花节位有较大关系，其相关系数分别达到0.81、0.75和0.58。

Adaptability of 3 Cowpea Varieties Planted in Autumn

The objective of this study was to investigate the adaptability of the two cowpea varieties, Qibao and Qiduo, in the local. Taking the Zhijiang28-2 as contrast, studying the relationship of the growth period, the yield and the first flower node, on the 3 cowpea varieties. The results showed that Qibao was inapplicability to plan in autumn with the reason of low yield and late date; Zhijiang28-2 and Qiduo was early-maturing variety, so they can be taken as the main variety planting in autumn. Otherwise, the results also showed that the yield of the 3 cowpea varieties has closed relation to the first flower node, its correlation coefficient can reach 0.81, 0.75, 0.58.
