Abstract

The invention provides a determination device for saturation moisture content of soil. The determination device is used for solving the technical problem of low determination precision of the determination device for soil saturation moisture content in the prior art. The determination device comprises a cutting ring device, a constant water-level water tank, a circulation water tank and a driving pump, wherein the constant water-level water tank is arranged in the cutting ring device; a water outlet is formed on a side face of the constant water-level water tank; the water outlet is aligned with the top end of the cutting ring device; the water level of liquid level in the circulation water tank is lower than the water outlet; the circulation water tank is connected with a water inlet pipeline; the tail end of the water inlet pipeline enters into the tank body of the constant water-level water tank along a clearance between the constant water-level water tank and the cutting ring device; the tail end of the water inlet pipeline is lower than the cutting ring device; and the driving pump is arranged on the water inlet pipeline. In a use process, the circulating water in the circulation water tank is driven by the driving pump, the circulating water entering into the constant water-level water tank enters into the cutting ring device from the bottom of the cutting ring device, and when water level of the constant water-level water tank reaches the water outlet, the circulating water returns to the circulation water tank through the water outlet.

Description

technical field [0001] The invention relates to the technical field of measuring soil water content, in particular to a measuring device for soil saturated water content. Background technique [0002] In the formation, transformation and consumption of water resources, soil water is an indispensable component; in plant ecosystems, soil water is the basis for the survival of various vegetation in agriculture and ecological environments; from the composition and structure of ecosystems Look, soil water is the link to maintain the nutrient chain of terrestrial ecosystems, has important resource value, and is also the most convenient freshwater resource in the world. Soil water is affected by various forces in the soil. Due to the different effects of various forces, soil water forms hygroscopic water, film water, capillary water and gravity water with different water physical characteristics. At present, the indicators used to describe soil water mainly include water content i...
