Soil parameter measurement device

Abstract

The invention provides a soil parameter measurement device, which comprises a soil moisture detection module, a solid conductivity detection module and a soil temperature detection module, wherein the soil moisture detection module comprises a double-explorer probe; the double-explorer probe comprises a first explorer and a second explorer; the soil conductivity detection module comprises four Wenner-configuration explorers; one explorer, which is located on an outer side, in the four explorers is the second explorer; a holding space is arranged in the interior of another explorer, which is located on the outer side, along an axial direction; the soil temperature detection module comprises a four-wire-system armored platinum resistor arranged in the holding space; the four-wire-system armored platinum resistor is insulating with the another explorer located on the outer side. The explorers of the soil parameter measurement device are reasonable in structural design; the problems of the mutual influence, the low precision and a big error, which are caused by the spatial abnormity of soil and exist during multi-sensor measurement, are avoided.

Description

technical field [0001] The invention relates to the technical field of soil detection, and more particularly, to a soil parameter measurement device. Background technique [0002] Soil is the basis of agricultural and forestry production. Rapid and effective collection and description of field information that affects crop growth is an important basis for the development of precision agricultural and forestry practices. Soil moisture, temperature and electrical conductivity are important parameters of soil that play an important role in the growth of crops. [0003] At present, there are many methods and devices for measuring soil moisture, temperature and electrical conductivity at home and abroad: [0004] The measurement methods of soil moisture content are roughly divided into two categories, one is traditional measurement methods, such as drying method and calcium carbide method, etc.; the other is modern measurement methods, such as tensiometer method, near infrared m...

AI Technical Summary

Problems solved by technology

At present, most of the sensors on the market collect one or two of the three parameters. Although multiple different sensors can be used to measure the three parameters, due to the spatial heterogeneity of the soil, that is, the same soil type, different time and different space The properties of the soil are different. First, when using multiple sensors to measure the same soil, it is difficult to ensure that different sensors are in the same space when measuring the same soil. The difference in the soil itself in different spaces will lead to the disadvantages of large measurement errors and low precision of multiple sensors. Secondly, the previous one The hole left after the sensor measurement will interfere with the measurement of the next sensor. Finally, multiple non-integrated sensors are inconvenient to carry and operate, and the cost is also high
