摘要
对阴山北麓春季土壤野外采样的含盐量进行室内理化分析表明,土壤已接近或达到盐渍化水平.在所采集的土壤样品中,中度盐渍化土壤、轻度盐渍化土壤及非盐渍化土壤所占比重分别为7.7%、53.8%和38.5%.对土壤浸提液电导率的测定表明,土壤含盐量与电导率呈较显著的线性相关关系.根据该区的实际情况,提出植树种草、井灌沟排、施用磷石膏、合理开发利用土地等措施,以改良土壤.
Salinized or almostly salinized soil was found by filed sampling and physical-chemical analysis in laboratory. The middling salinized soil,the slight salinized soil and the unsalinized soil accounts for respectively 7.7% ,53.8% and 38.5%. By measuring the electro-conducting of the soil solution,it is proved that soil salt content and electro-conductivity has distinct linear relationship. According to actual circumstance in north foot of the Yinshan Mountains, plant forestry and grass, irrigate by well and draining by channel ,gypsum the land and reasonable usage of land should be taken.
