[0002] As a comprehensive technology, drip irrigation under film is widely used in Xinjiang cotton fields. This technology has promoted the rapid development of Xinjiang oasis cotton fields. Drip irrigation under film can increase the temperature and humidity of the soil in the early stage of cotton fields, and use irrigation water to transport topdressing fertilizers to the cotton root system, which has a significant effect of saving water and increasing production. However, compared with conventional ground irrigation, cotton fields under film drip irrigation require multiple consecutive irrigations, and the movement and diffusion of water are also different from natural precipitation.

[0003] For a long time, research on water and fertilizer utilization has mostly focused on water and salt, while there have been fewer studies on the vertical movement of fast-acting nutrients (such as nitrate nitrogen) in the soil under drip irrigation conditions. This type of research requires collecting and measuring the vertical leaching amount of water and the total vertical movement of mineral nutrient ions in columnar soil at different depths in the same cotton field.

[0004] Therefore, after drip irrigation and fertilization in cotton fields, how to provide a device that can collect the total amount of vertical movement of water and fertilizer in the in-situ soil at different depths is a technical problem that technical personnel in this field urgently need to solve.
