河套灌区盐渍化人工草地土壤含水量、含盐量及pH变动规律

对河套地区盐碱荒地，弃耕地种植耐盐碱优良牧草后的土壤含盐量、含水量、ｐＨ变化规律，对土壤含水量、含盐量、ｐＨ相互变化关系及春季、秋季土壤含盐量、ｐＨ变化规律连续数年进行了分析测定。在大量分析数据基础上，总结探讨了种草对盐碱地土壤含盐量，ｐＨ的影响。

Soil Water and Salt Contents as Well as Their Changing Laws Governing pH Values on Salinized Grassland in the Hetao Area of China

On the wastelands and the abandoned cultivated lands in the Hetao salinized rangeland area,after we had been planting tbose alkaline-saline-resistant & good quality forage grasses,the water and salt contents in the soil and their changing laws governing pH values, then all those soil water and salt contents as well as mutually changing relationship of pH value in the soil layer in both spring and autumn seasons,in addition to those laws concerning changing & variational situation of pH values then analyzed and determined. On the basis of analytical data obtained in great amount,the authors have discussed and concluded that quite lots of influences affected the soil salt contents and pH values offered for our reference.
