尕海地区弃耕地土壤可溶性盐分测定

１９９０～１９９３年在柴达盆地尕海地区弃耕地进行土壤可溶性盐分测定，测定结果，该地区土壤盐分组成为氯化物－硫酸盐和硫酸盐－氯化物，大部分地区耕层盐分含量小于１０ｇ．ｋｇ＾－１，少部分盐荒地表层含盐量高达７０ｇ．ｋｇ＾－１，牧草生长季节中，土壤盐分含量最低期在６月份。

Measurement of Soluble salt content in Abandoned land of Gahai Area

The measurement of soluble salt in soil was carried out in Gahai ChidamuBasin from 1990 to 1993.The result showed that the salts in the soil were mainly chloride-sulphate and sulphate-chlorate. The salinities in the cultivated layer were mostly less than10g/kg bus as high as 70g/kg in a very few samples.During herbage growing season,thelowest salt content occuresd in June.
