摘要： To measure soil compactness distribution on seedbed, a new test device of soil outline and compactness distribution on seedbed based on sensors was designed. The paper elaborated working principle and structure of the device and its working parameters were determined. Calibration experiments obtained linear equation between L and I for distance sensor and linear equation between m and I and linear equation between F and I for each pressure sensor. Field experiment showed that designed device could test soil outline and soil compactness at the same time.
