Description
Technical Field
The utility model relates to an agricultural pollution detects technical field, specifically is an experiment is with field soil eluviation normal position layering collection device.
Background
Agricultural non-point source pollution is defined as non-point source pollution in agricultural production activities, such as water and soil loss caused by unreasonable artificial management activities, artificially applied pesticides and chemical fertilizers, sewage generated by daily life of residents and other organic or inorganic pollutants, and the pollution threatens human health and survival due to interaction in ways of surface runoff, underground leakage and the like in the processes of rainfall erosion, ice and snow melting or irrigation. Leaching is one of the important ways for the loss of inorganic salts such as nitrogen and phosphorus in soil. For the monitoring of leaching loss, home and abroad are accepted, and the most common methods are in-situ field monitoring and leaching simulation experiments. In-situ field monitoring tests mostly require that a runoff field and a seepage pool are built in a test area or a soil solution suction filter is buried in soil for collecting soil leaching solution, and the method requires long-term monitoring in the field. At present, the methods for researching the soil leaching migration rule mainly comprise an indoor soil column simulation method, a seepage pool method, a field soil column method, a pottery clay suction cup method and a water collecting tank method. Under the condition that a standard method for monitoring soil leaching is not established at home and abroad, the research on a relatively accurate, simple, convenient and economic field leaching loss collecting device has a wide development prospect in the field of soil leaching research.
At present, the methods for researching the soil eluviation movement law are mainly an indoor soil column simulation method, a seepage pool method, a field soil column method, a pottery clay suction cup method and a water collecting tank method. Various methods have some defects, for example, the soil layer structure is difficult to ensure by an indoor soil column simulation method when filling the soil column, the actual field environment cannot be reproduced by the research environment, and the indoor research is limited; the seepage pool method needs to carry out excavation operation in the field, so the cost is higher, the occupied area is larger, and the movement is not easy; in the field soil column method, certain pressure needs to be applied to the soil column in actual operation, so that the flow speed and the direction of the leaching water are influenced; the main disadvantage of the clay suction cup method is high cost; on one hand, the water collecting tank method needs to excavate a water tank and also has influence on the movement of soil moisture.
Currently, each pipe of the existing soil leaching solution collector can only collect soil solution of one depth. When the leaching loss of different soil layers is researched, the soil leaching solution of a target layer is collected in different layers. Therefore, if 3 levels of soil eluviation need to be collected, 3 eluviation tubes with different depths are often embedded in the arrangement process of the experimental sample plot, so that the cost of the experiment is increased, the area of the experimental land is increased, and the error of the experiment is increased.
