摘要
随着干旱区盐碱化的不断加剧,农业灌溉用水的质量成为制约干旱区农业发展的一个重大问题。所以在对吐鲁番市灌溉用水,如渠水、泉水、机井水、坎儿井水的水质(pH值、电导率、八大离子)进行检测的基础上,用不同的分析方法对灌溉用水质量进行分析。得出的结论是:渠水水质普遍较好,对农作物基本没有影响;渠水下游、机井水及坎儿井水水质一般;胜金口的泉水及附近机井水水质较差,可能会使灌溉土壤中度盐化;春季煤窑沟下游各种灌溉用水均为重度盐碱水,极易加剧土壤盐碱化。
With the aggravation of salinization in arid areas,agricultural irrigation water quality has become a major problem that restricts agricultural development in arid area.Based on the investigation of irrigation water quality indexes,including pH value,conductivity and eight kinds of ions,in Turpan city,including canal water,spring water,well water,Karez water,the irrigation water quality is analyzed with different methods.The conclusion is that the quality of canal water is generally good and has no effect on the crop;the quality of downstream water,the well water and Karez water is just fair;the quality of spring water in Shengjinkou or the well water near that is poor and may cause soil moderate salinized;all kinds of irrigation water near the Meiyaogou downstream in spring are severe saline alkali water and may highly possible to aggravate soil salinization.
