A device for measuring the moisture content of litter in the field

Abstract

The invention discloses a field withered litter water content measuring device. The field withered litter water content measuring device comprises a separating plate, a box body and a box cover. The box cover is rectangular. The size of the box cover is the same as the size of the inner wall of the box body, four corners of the box cover are symmetrically provided with four fixing bolts, the box cover is provided with a plurality of water permeable holes. The box body is rectangular. Two opposite inner side walls of the box body are symmetrically provided with two heating sheets, the upper surface of the bottom of the box body and the lower surface of the box cover are symmetrically provided with pressure sensors, the upper surface of the box cover is provided with a gravity sensor. The field withered litter water content measuring device is capable of solving existing problems in a current withered litter water content measuring method that a measuring speed is slow and the water content is difficult to be directly measured in the field, simple in structure, and convenient to carry.

Description

technical field [0001] The invention relates to the technical field of measuring the water content of forest litter, in particular to a device for measuring the water content of wild litter. Background technique [0002] Forest litter is one of the main contents of forest hydrology research, and it is also one of the main functional layers of forest ecosystems. It not only affects the process of precipitation production and confluence, but also has a great impact on evapotranspiration in forest areas, realizing forest litter. It is of great significance to quickly and accurately measure the water content of the layer. Compared with soil, the structure of litter layer is loose and its thickness is generally thinner. The common soil moisture measurement method is difficult to be directly used to measure the moisture content of litter layer. [0003] At present, there are few studies on the measurement method of litter moisture content. The relatively mature and reliable measu...
