[0003] At present, the commonly used lysimeters have the following problems: 1. Single-channel structure, low precision, generally 500 grams, difficult maintenance, complex data processing, not intuitive, not conducive to data analysis and observation, no data during use For comparison and reference, it is impossible to measure the comparison data at the same time and under the same environment, which affects its promotion and use effect; 2. Due to structural limitations, it is troublesome to disassemble and

Abstract
The invention relates to a four-channel lysimeter which is characterized by comprising four single-channel lysimeter and a single chip microcomputer with display functions. Each single-channel lysimeter comprises a cylindrical container, a triangular support assembly, a leakage device and a weighing sensor, the triangular support assemblies are supported at the bottoms of the cylindrical containers, the leakage devices and the weighing sensors are arranged at the bottoms of the cylindrical containers, the triangular support assemblies comprise lower triangular brackets, upper triangular brackets and spring pillars, the upper triangular brackets are fixedly connected with the bottoms of the cylindrical containers, the spring pillars are connected with the upper triangular brackets and the lower triangular brackets, liftable upright columns for mounting the weighing sensors are arranged on the upper surfaces of the lower triangular brackets, the weighing sensors are clamped between the bottoms of the cylindrical containers and the top surfaces of the liftable upright columns, a plurality of sensor mounting holes are formed in the container walls of the cylindrical containers from top to bottom, and liquid outlets of the leakage devices are connected with leakage weighing instruments. The four-channel lysimeter has the advantages that the four-channel lysimeter is convenient to maintain and low in cost, measurement data are high in accuracy, visual observation effects can be realized, four different measurement results can be simultaneously observed, and accordingly the data can be conveniently comprehensively analyzed.
Description
technical field [0001] The invention relates to a four-channel lysimeter, which is suitable for the lysimeter used in the fields of water conservancy, meteorology, hydrology, agriculture, animal husbandry and the like. Background technique [0002] The lysimeter is an important soil ecological monitoring instrument, through the accurate monitoring and analysis of the soil column weight and soil moisture in the in situ soil-plant column system, to study the soil carbon and nitrogen water cycle, including water balance, material balance, Soil ecological conditions such as water migration, solute migration, transpiration and transpiration are suitable for long-term monitoring of ecosystems such as farmland, grassland, forest, river wetland, swamp, root cellar, building foundation, etc., and are widely used in agriculture, forestry, environmental protection, meteorology, Hydrology, water conservancy and other research fields. [0003] At present, the commonly used lysimeters ha...
