Embodiment 1

[0018] Example 1, see figure 1 , processed into a water supply pipe 1 and an infiltration chamber 2. The infiltration chamber 2 is a cylindrical container of stainless steel or other hard material with one end open and the other end closed. The edge of the open end has a sharp slope to minimize disturbance The water supply pipe 1 is a transparent cylindrical plastic pipe, and a scale 7 is pasted outside the pipe wall for observing the water level in the water supply pipe 1. In order to improve the measurement accuracy, the infiltration chamber The radius R of 2 should be greater than the radius r of the water supply pipe 1, and the ratio R / r between the two should be greater than or equal to 2; the water supply pipe 1 is tightly connected with the infiltration chamber 2 through the screw hole 3 on the upper part of the infiltration chamber 2, A control switch 4 is installed at the lower end of the water supply pipe 1 to control the water; an air vent 5 controlled by an elastic...

Abstract

The invention discloses a method and a special device for measuring soil hydrodynamic parameters in situ in the field. The method is characterized in that a measuring system comprises a water supply pipe 1 and an infiltration chamber 2 which are connected with each other; and the radius of the infiltration chamber is larger than that of the water supply pipe; therefore, the observing accuracy of the infiltration process is improved; and according to the invention, the saturated hydraulic conductivity and wetting front suction force of the coil are figured out according to a continuous falling head vertical infiltrating principle; the measuring process of the soil hydrodynamic parameters is simplified; the measuring time and the cost are saved; the method and the special device can be achieved in technology; and moreover, the equipment price is greatly reduced and the method and the special device are easy to promote and apply.

Description

Technical field: [0001] The invention relates to the technical field of soil moisture migration parameter measurement, in particular to a method and a special device for in-situ measurement of soil hydrodynamic parameters in the field. Background technique: [0002] Soil water is the main carrier of soil pollutants and industrial chemicals, so the acquisition and mastery of soil hydrodynamic parameters is very critical for understanding and controlling soil water and surface water pollution. As the place where crops grow, the soil water infiltration characteristics directly affect the irrigation quality and irrigation efficiency, and ultimately affect the growth and development of crops and the utilization efficiency of water resources. Soil hydrodynamic parameters are the main parameters affecting the soil water cycle process, how to quickly and accurately determine them has always been a hot issue in the field of soil physics. At present, there are many methods for measur...
