Embodiment Construction
[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0039] In the embodiment of the present invention, such as figure 1 , figure 2 As shown, a method for measuring soil moisture characteristic curve and unsaturated hydraulic conductivity is provided, including the following steps, step 1, loading and undisturbed soil, and setting several tensiometers;
[0040] Step 2: Seal the bottom of the fully saturated soil column; and ensure that there is no water leakage or seepage, and adjust the tensiometer to make it in a normal working state.
[0041] Step 3, measure 1 to 2 times a day according to the water consumption of the soil column and the change...
