Lysimeter is a kind of instrument for determination of evapotranspiration in farmland. The research and application of the domestic andforeign lysimeter are continuously developed. The equipment has been improved from the non-weighing to the weighing type, and the observationmethods from manual to informatization and automation. The research field has also expanded to agriculture, forestry, ecology, climate change andetc.. Meanwhile, the performance update can meet the requirements of multi-time, multi-objective and multi-factor observation. Based on theanalysis of the application status at home and abroad, the design technology of the new type lysimeter was proposed to meet the hydrological cycleand evapotranspiration research.
