C. voltage stabilizing power source 15 is connected with the milliammeter 13 or themicroampere 14 by a switch, the milliammeter 13 and the microampere 14 are connected with the resistor serializer (12).

Description

technical field [0001] The invention relates to a soil moisture measurement system, in particular to a soil moisture layered measurement system. Background technique [0002] The measurement of soil moisture storage and its change over time is an important basic work in soil improvement, soil state monitoring, water-saving irrigation in modern agriculture, and water-saving grass planting in soil industrialization. It is convenient, quick, and accurate to measure the moisture content and its changes in soil or modified soil, and can provide direct test basis for soil improvement, water-saving irrigation, and restoration of vegetation. Existing soil moisture measurement methods include soil drying method, alcohol method, calcium carbide method, resistance block method, gamma ray method, negative pressure meter method, microwave method, neutron method, etc. These methods and measuring devices are not easy to affect the soil. Determination of layered water storage, great interf...
