Summary: | The invention discloses a method for measuring a physical parameter S of soil, relating to a method for solving a performance parameter, and aiming at solving the problems that measurement instruments are expensive and measurement periods are long as the measurement of the physical mass parameter S of the soil depends on a van Genuchten equation of a water soil water characteristic curve. The method comprises the following steps: step one, sieving an air-dried soil sample by virtue of a 2-mm sieve and dividing the soil sample into two parts; step two, measuring a saturation moisture content theta s and a field moisture capacity theta (fc) by using the first part of the soil sample; step three, measuring a residual moisture content theta r by using the second part of the soil sample; step four, obtaining a parameter n according to a formula as shown in the specification; and step five, obtaining the physical parameter S of the soil according to another formula as shown in the specification. |
