Description

Technical field

[0001] The invention belongs to the technical field of agricultural, forestry and water conservancy engineering equipment, and particularly relates to an embedded monitor used for groundwater constant level compensation of a lysimeter. Background technique

[0002] The groundwater constant level compensation of the lysimeter is an indispensable monitoring data in the calculation of water balance, and it is an indicator reflecting the utilization of water resources by plants. In order to quantitatively determine the impact of groundwater replenishment on the growth process of plants, it is often necessary to accurately control the constant groundwater level of the lysimeter and perform constant replenishment and drainage measurements. Domestic and foreign lysimeters are divided into weighing lysimeters and non-weighing lysimeters according to different water measurement methods. The weighing lysimeter is the weighing method. Its weighing system has a complex struc...
