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

Abstract

The invention discloses an experimental method used for research of thin film water migration laws. The experimental method comprises following steps: experimental soil sample is delivered into a soil column in layers; ionized water with a certain concentration is delivered into a water supply device, and a small amount of plant oil is added for oil seal of the ionized water; a certain amount of water is added into the water supply device every a period of time so as to ensure that the water level is higher than a buffer layer of the soil column; in experimental processes, data acquired by a humidity temperature sensor is sent to a data acceptance and analysis system via a wireless data sent terminal for analysis; and a certain period of time later, the soil is sampled for another time so as to measure water content and ion concentration of soil of different depth. The experimental method is capable of realizing accurate research on thin film water migration rate under different soil conditions, so that reliable experimental base is provided for research of water migration of soil in arid areas. The invention also discloses an experimental device used for the experimental method which is used for research of thin film water migration.

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...
