摘要
盐池四墩子井灌区地处干旱山区,居民饮用和灌溉用水奇缺.本文按毒理学指标(氟含量)和咸淡程度(总矿化度)对井水的可饮用程度作了计算,按灌溉后能否产生土壤盐化或碱化给出了评价,由于取样较多,评价指标多样,因此评价结果准确可靠,已用于生产实际.
Siduizi irrigation area of Yanchi is located in a dried mountain region. Resident drinking and irrgation water are exceedingly scare here. This paper gives the calculation about the degree of drinkability of well water depending on the content of F and minirals. This paper also gives evaluation about the salinization that can be caused by irrigation .
