以贵阳青棒豆为试材,研究了不同采收成熟度和时间采收菜豆贮藏期间主要理化指标变化规律的影响。研究显示:不同采收成熟度和时间对菜豆采后保鲜效果影响显著,其中,六成熟时采摘豆荚期间品质变化较缓和,贮藏24 d营养成分损失较小,豆荚纤维化、黄化不明显,消费者易接受;5月中旬采收菜豆的贮藏品质显著高于其他几个采收期,有利于贮运。因此,贵阳青棒豆大棚栽培以4~5月份气候条件最佳,六成熟时采摘。

Common bean( Phaseolus vulgaris L) Cv. Guiyang-Qingbangdou were used as material,the effect of preservative quality on Guiyang-Qingbangdou from different maturities and picking up time during storage was investigated. The results showed that the effect was significantly,and the change of quality is moderate for the pods picked at 60% of maturity. The nutrients loss relatively small,less pods fibrosis and brewing is not obvious,the consumers are easy to accept after 24 hours. The preservative quality on Guiyang-Qingbangdou of harvest in mid-May was significantly higher than other harvest time. Therefore,the best climate conditions of Guiyang-Qingbangdou is April to May in greenhouse cultivation,and the best for the preservation is 60% maturity beans.
