摘要 为调查平顶山市烟田灌溉水水质,采集了3个主要植烟县49个灌溉水样进行分析。结果表明:①3个烤烟主产县比较,全盐含量和电导率顺序相同,均为:郏县>叶县>宝丰;氯含量和pH顺序相同,均为:叶县>宝丰>郏县。②叶县和宝丰灌溉用水的全盐量、pH和电导率全部符合烤烟生产要求,叶县85%、宝丰86.67%的灌溉水氯含量处于适宜水平。郏县灌溉用水氯含量、pH和电导率全部符合相关标准,92.86%的灌溉用水全盐量处于适宜水平。

Abstract In order to survey irrigation water in tobacco-growing areas in Pingdingshan, 49 water samples taken from 3 tobacco-growing counties were analyzed. The results showed that: ① Compared three main tobacco growing districts, the order of irrigation water salinity and conductivity from high to low in tobacco-growing areas in Pingdingshan is about: Jiaxian>Yexian >Baofeng. For chlorine content and pH of irrigation water, the order is: Yexian>Baofeng>Jiaxian. ②Salinity, value of pH and conductivity of Baofeng and Yexian′s irrigation water accord with tobacco production requiration.The chlorine content of irrigating water are proper in Yexian and Baofeng is 85 percent and 86.67 percent. The chlorine contents, value of pH and conductivity of Jiaxian accord with tobacco production requiration. The salinity contents in about 92.86% of tobacco growing areas in Jiaxian County are suitable for tobacco cultivation.

平顶山烟区地处豫西山地和淮河平原的过渡地带,为大陆性季风气候。近年来雨量分布不均日趋明显,干旱和局部洪涝灾害时有发生[1]。为满足烟叶生长的需要,在充分利用降水的基础上合理应用灌溉显得尤为重要。烟草是忌氯作物,烟草所吸收的氯主要来自植烟土壤、降雨和灌溉水。目前我国许多烟区已开展灌溉水水质对烟草影响的研究[2-5],而关于平顶山市烤烟主产区灌溉水水质的调查还未见报道。为此,笔者采集了平顶山市3个烤烟主产县的灌溉水样,对其水质状况进行调查研究,旨在摸清烟叶灌溉用水水质特别是氯含量等影响烟叶品质的一些指标,以期为平顶山烟区优化烟叶布局和科学灌溉提供依据。
