Problems solved by technology

However, due to the large gap between the natural environment of indoor soil and field soil, including temperature, humidity, and wind speed, and the traditional indoor measurement speed is relatively slow, the soil structure will inevitably be damaged during the soil sampling process, and it is difficult to obtain accurate data.

Abstract

The invention provides a device and a method for automatically monitoring and evaluating soil parameters. The device comprises a measuring device and a main control device, wherein the measuring device is used for generating a nuclear magnetic resonance signal for original soil to be tested according to the nuclear magnetic resonance principle; the main control device is electrically connected with the measuring device, and is used for analyzing the original soil to be tested immediately according to the nuclear magnetic resonance signal to obtain the soil parameters. According to the scheme, the water content, the porosity, the field capacity and the wilting coefficient of the soil, the relationship between the soil water potential and the soil moisture content, and the like can be researched.

Description

technical field [0001] The invention relates to the technical fields of water resource science, agronomy and ecological experiment research, in particular to a soil parameter automatic monitoring and evaluation device and method. Background technique [0002] It is urgent to carry out relevant research work in monitoring soil moisture content, porosity, field water capacity and wilting coefficient in different periods, and evaluating soil moisture, which is also a research hotspot in water resources, agronomy, ecology and other related fields . [0003] In the current research work, the determination of soil parameters is mainly based on the traditional indoor sampling method, specifically: take a number of soil samples to be tested, after drying, compression, water injection, instrument weighing, observation, The corresponding calculations are then performed to finally obtain the soil parameter values. However, due to the large gap between the natural environment of indoo...
