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p H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、p H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、p H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。
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.
