Problems solved by technology

[0002] Among the studies on the four waters of atmospheric precipitation, surface water, soil water, and groundwater, there are relatively few studies on soil water, while film water is a component of soil water, and its movement mechanism is still unclear. Therefore, soil water in arid areas The question of origin remains highly debated

Embodiment Construction

[0023] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] like figure 1 As shown, the present invention provides an experimental device for studying the law of thin film water migration, including a soil cylinder 1, a water supply device 2, a temperature and humidity sensor 3, a wireless data transmitting terminal 4, a data receiving and processing system 5, and a soil extractor 6, The soil column tube 1 includes an upper experimental soil sample layer and a lower buffer layer, and the inner diameter of the buffer layer is greater than the inner diameter of the experimental soil sample layer; the water supply device 2 is connected with the lower buffer layer of the soil column tube 1 through a conduit, and the side wall of the device is There are two fixed water level scale lines engraved on it, the lower fixed water level scale line is equal to the buffer layer of the soil column t...

Abstract

Oil seal.Add a certain amount of water to the water supply device every time to ensure that its water level is higher than the buffer layer of the soil cylinder.During the experiment, the terminal was transmitted to the data receiving and processing system through the wireless data transmitting terminal through wireless data.And sampling the soil after a period of time, testing the moisture content and ion concentration of different deep soil.Through this experimental method, the thin film water migration rate in different soil environments can be accurately studied.Provide a reliable experimental foundation for the research of soil water transportation in the arid area.The present invention also disclosed an experimental device for the aforementioned study of thin film water transportation experiments.

Description

technical field [0001] The invention relates to the field of soil water environment experiments and tests, in particular to an experimental device and method for studying the law of membrane water migration. Background technique [0002] Among the studies on the four waters of atmospheric precipitation, surface water, soil water, and groundwater, there are relatively few studies on soil water, while film water is a component of soil water, and its movement mechanism is still unclear. Therefore, soil water in arid areas The question of provenance remains highly debated. Existing studies have shown that precipitation in arid areas is difficult to infiltrate into the soil to a certain depth, and soil water is mainly recharged by groundwater. Groundwater can only reach a certain height through capillary water recharge and cannot go up; further up, thin-film water migration plays a major role. Under this premise, it is of high scientific value and application prospect to design...
