土壤导水率是农田排水规划的重要参数。本文就钻孔法测定土壤导水率的试验方法,以及作者为该试验而研制的新型土钻的结构功能作了介绍,并对钻孔法不同计算公式的计算结果进行了比较,认为得出厄恩斯特法较为符合实际情况。
Soil hydraulic conductivity is an important parameter of farmland drainage planning. In this paper, the experimental method of measuring soil hydraulic conductivity by drilling method and the structural function of the new type of earth drill developed by the author for this test are introduced. The calculation results of different calculation formulas of drilling method are compared, and it is concluded that Ernst method is more in line with the actual situation.
