一、方法介紹地下水和土壤中可溶性鹽总量的测定,是了解土壤和改良鹽土的一个不可缺少的手段。目前在这方面一般采用的方法有烘干法和电阻法,但这二个方法只适合于条件較好的試驗室,不宜普遍推广,如重量法,它需要很多仪器設备,操作手續較复杂,速度慢,成本高。电阻法測定速度虽比較快,但結果也不够令人滿意。 Methodology The determination of the total amount of soluble salts in groundwater and soil is an indispensable means of understanding the soil and improving saline soil. Currently in this area are generally used methods drying method and resistance method, but these two methods are only suitable for better laboratory conditions, not universal promotion, such as gravimetric method, which requires a lot of equipment, more complex procedures , Slow, high cost. Although the speed of resistance measurement is relatively fast, the result is unsatisfactory.
