摘要/Abstract

摘要： 分析了连作障碍对豇豆[Vigna unguiculata （Linn.）Walp]新品种鄂豇豆5号、鄂豇豆8号特征特性的影响。结果表明,连作障碍会造成豇豆叶片小、荚轻、荚短、荚细、早衰、病虫害严重,直接导致前期产量、总产量减产明显。应避免豆科作物连作,尽量实行水旱轮作或异科轮作。

关键词: 豇豆[Vigna unguiculata （Linn.）Walp], 重茬连作, 植物学性状, 产量性状

Abstract: The effects of continuous cropping obstacles on the characteristics of two new cowpea[Vigna unguiculata （Linn.）Walp] varieties Ejiangdou No.5 and Ejiangdou No.8 were analyzed. The experimental results showed that continuous cropping obstacles could cause small leaves, light pods, short pods, thin pods, premature failure, and serious pests and diseases, which could directly lead to a significant reduction in the output of the early stage and total output. The continuous cropping of leguminous crops should be avoided, and paddy-upland rotation and different families rotation shall be carried out.

Key words: cowpea [Vigna unguiculata （Linn.）Walp], continuous cropping, phytology characters, yield characters
