Abstract

The invention discloses a layered soil moisture lysimeter sensor and an installation method thereof. The sensor comprises a plurality of layers of horizontally disposed lysimeter moisture-sensitive sheets, fixing seats are disposed among the lysimeter moisture-sensitive sheets, the fixing seats of each layer of the lysimeter moisture-sensitive sheets are socketed and fixed by vertical tube sections, a plurality of positioning rods are inserted among each layer of the lysimeter moisture-sensitive sheets for supporting and positioning, conductivity electrode rings and thermosensitive devices are installed amongy each layer of the lysimeter moisture-sensitive sheets are installed with, and original test soil is fully filled among each layer of the lysimeter moisture-sensitive sheets. The sensor can monitor soil moisture lysimeter amount of test points within the depth below ground all the day, has the advantages of high precision, good resolution, easy installation, low cost, real-time and continuous data collection and the like, is suitable for observation of soil moisture movement on a field scale, and is an advanced instrument for the soil moisture movement information collection system.

Description

technical field [0001] The invention relates to a sensor for testing soil moisture evaporation and infiltration, in particular to a layered soil moisture lysimeter sensor and an installation method thereof. Background technique [0002] At present, methods such as drying method, negative pressure meter method, neutron moisture meter method, time domain reflectometry or frequency domain method are usually used to collect soil moisture lysimeter data. The problems of exchanging information data, high environmental requirements, low degree of automation, shallow test depth, and large interference from human factors have brought inconvenience to the information collection and simulation research of soil moisture migration. Contents of the invention [0003] The object of the present invention is to provide a layered soil moisture lysimeter sensor and a placement method thereof in order to remedy the defects of the prior art. [0004] The present invention is achieved through ...
