Abstract

The invention discloses a soil porosity testing device based on superfluid, and relates to the technical field of porosity measuring devices. The soil porosity testing device based on the superfluid is characterized by comprising a superfluid container, a cylindrical glass cover, a cylindrical soil loader and a measuring cylinder. The superfluid container is arranged above the cylindrical glass cover and is provided with scales and a valve; the lower bottom surface of the cylindrical glass cover is a detachable glass surface, a position adjusting screw is arranged below the lower bottom surface of the cylindrical glass cover, and a superfluid container fixing groove and a cylindrical soil loader fixing groove are formed in the lower bottom surface of the cylindrical glass cover; the upper top surface of the cylindrical glass cover is provided with a handle, a horizontal pipe, a gap for mounting the superfluid container and a circular ring frame; the cylindrical soil loader is installed on a cylindrical soil loader fixing groove, and an inclined ring groove with an outlet is formed in the side face of the cylindrical soil loader; and the measuring cylinder is arranged below the outlet of the inclined ring groove. The device can be used for testing the soil porosity.

Description

technical field [0001] The invention relates to the technical field of porosity measuring devices and methods, in particular to the technical field of soil porosity measuring devices and methods, in particular to a superfluid-based soil porosity testing device. Background technique [0002] Soil porosity refers to the ratio of the pore volume between soil particles to the total soil volume. It is an important physical property index reflecting the compactness of the soil. The size of the porosity is related to the soil type, texture, and organic matter content. Nutrient conversion, plant root growth, etc. have important effects. [0003] There are empirical calculation method, mercury intrusion method and image processing method to measure soil porosity. [0004] Although the empirical calculation method is a traditional method for obtaining porosity, the volume occupied by water between soil layers is not deducted in the calculation. Since water between soil layers is los...
