Background

The leaching of the underground water refers to the process that part of components in the surface layer of the soil enter the water and are taken away along with the water through the actions of dissolution, hydration, hydrolysis, carbonation and the like of the underground water, and the soil is gradually acidified along with the leaching action. For example, in the upper part of a soil section in a wet area, water is leached from the surface of the earth to the lower part for a long time, so that soluble substances and fine soil particles in an upper soil layer are leached, and a leaching layer, namely a soil layer with light soil color, thick texture, high acidity and low fertility, is gradually formed. The leaching layer is also called layer A, and the bad characters can be improved by measures of farming and fertilizing, especially increasing organic fertilizer and clay soil fertilizer.

However, in recent years, with the popularization of production and use of chemical fertilizers, the loss of various nutrient components (such as nitrogen, phosphorus, potassium and the like) in soil is increasingly serious, and beneficial elements in the soil are vertically and downwardly migrated to the position below a plant root system active layer along with water to cause loss, so that the nutrient loss of farmlands is caused, the nutrient utilization efficiency is reduced, meanwhile, most of leaching elements finally enter a water body environment to pollute ground water bodies such as rivers, lakes and the like, and the leaching element is one of the most important agricultural non-point source pollution sources and threatens the drinking safety of underground water. Therefore, the method has great significance for accurately collecting and monitoring the underground water leaching solution, correctly analyzing the soil nutrient balance, exploring the nutrient circulation process and carrying out environmental risk assessment.

At present, the underground water leaching solution collection is generally carried out by embedding a soil leaching solution sampling device under the root system of a soil crop, then bringing the leaching solution of a research sample plot back to a laboratory for detection, and the leaching solution destroys the original existing state in the processes of collection, movement and long-time exposure to air, and has certain influence on the determination of element leaching loss conditions. Patent CN208579959U discloses an automatic monitoring device for farmland soil leaching solution, which comprises a leaching disc, an experimental bottle, a sample bottle, a water level sensor, a water inlet pipe, a water intake pipe, a water pump and a motor, wherein the leaching disc is positioned above the experimental bottle and is connected to the experimental bottle through the water inlet pipe; a water level sensor is arranged in the experiment bottle and connected to the motor; the experiment bottle is also connected to the sample bottle through a water taking pipe; the water pump is used for pumping the air in the sample bottle and is driven by the motor. Can be convenient for experiment automatic determination, and the collection drenches the solution and does not need artifical on duty. However, sampling errors are easily caused for a long-time sampling work and real-time monitoring of the leaching solution and the soil cannot be realized.
