Abstract:

Soil is the basis of agricultural and forestry production, and it is of great significance to obtain soil information efficiently and comprehensively for soil management. Due to the complexity of soil chemical analysis method, it is difficult to obtain the soil chemical component information comprehensively. As a non-destructive, real-time and high-throughput analysis method, mid infrared spectroscopy (MIR) has the ability to obtain soil organic environmental information efficiently and accurately. It can provide a large number of basic data for soil environmental monitoring, digital mapping, agricultural and forestry production, and help to realize the real-time monitoring of soil environment and the informatization of agriculture and forestry. In this paper, we briefly introduced the detection process and data processing methods of soil environmental spectral information obtained by mid infrared spectroscopy technology, reviewed the research progress of soil spectral feature extraction and influencing factors in recent years, and discussed the significance and future development direction of soil science.
