Abstract

The invention provides an experimental device used for simulating the water transporting process in soil. The experimental device comprises an experimental container, an operating table and a water control device, wherein openings are formed in the top end and the bottom end of the experimental container respectively, a filter head is installed at the bottom end of the experimental container, a lifting device is arranged on the operating table, the experimental container is detachably installed on the lifting device, the lifting device is suitable for moving along the operating table in a reciprocating mode in the vertical direction, and the water control device is arranged at the top end of the experimental container and can control the water volume and water to seep into the soil uniformly. By adjusting the height of the water in a water tank, different irrigation and rainfall conditions can be simulated; soil water transporting parameters are measured accurately; in addition, soil nutrition transporting parameters can be measured; by changing the water inlet direction, transporting parameters of underground water rising can be simulated; as the soil water and nutrition transporting parameters are detected at the same time, the soil water and fertilizer coupling mechanism is analyzed easily, and the experimental device has great theoretical guidance significance in guiding the irrigation water volume and the water-saving technology.

Description

technical field [0001] The invention belongs to the category of soil science and agricultural science, and in particular relates to an experimental device suitable for simulating the migration process of water and soluble nutrients in soil under different irrigation and rainfall conditions. Background technique [0002] Soil moisture in farmland is a key factor affecting crop yield and soil fertilizer efficiency. The movement of soil moisture drives the movement of soil nutrients, which has an important impact on the absorption of crops and the loss of soil nutrients. Irrigation and rainfall are the main sources of soil moisture. Clarifying the influence of soil physical and chemical properties on soil moisture migration is a key issue for rational irrigation and water-saving agriculture. It also has important theoretical guiding significance for improving soil and other agronomic measures. Agronomic techniques such as water saving and fertilization are the key areas of sust...
