摘　　要：本文较详细介绍了负压直读式盐田测修仪的工作原理、结构特点和使用方法等方面的情况，该仪器垠据“与水面联通的管道内负压一定时，管内液面高度与水面距离也为一定值”原理研制而成，具有操作方便、简单，测渗精度高等特点，有较大的经济开发价值。The operational principles，structrural characteristics and usage of thesalt field negative pressure and direct－reading lysimeter are introduced in this paper．When the negative pressure in the tube connected to the water level is definite，the dis－tance between the level hight in the tube and the water level is also definite．Accordingto this principle，the lysimeter is developed．It is characterized by simple convenlent op－eration and high precision，and worthy to be developed economically．
