Abstract

The invention relates to the technical field of geochemical exploration and especially relates to a method and a system for fast measuring distribution of a nitrogen element on the soil surface. The system comprises an enclosed negative pressure cabin, an analysis device, a two-dimensional moving sample bench, a laser excitation device and an atomic spectrum collection device. The analysis device controls a movement state of the two-dimensional moving sample bench. The laser excitation device and the atomic spectrum collection device are used respectively for exciting and collecting a trace atomic emission spectrum of the soil surface and analyzing the content of a nitrogen element in an irradiation position on the soil surface. The analysis device adopts control, calibration and quantitative regression algorithms, and is used for calculating content of a nitrogen element in different irradiation positions on the soil surface and automatically drawing a nitrogen element distribution map. Through the method and the system for fast measuring distribution of a nitrogen element on the soil surface, distribution maps of organic nitrogen, available nitrogen and a nitrogen element on the soil surface are obtained and the influence produced by a nitrogen element in air on a measure result is eliminated.

Description

technical field [0001] The invention relates to the technical field of earth exploration, in particular to a method and system for quickly measuring nitrogen element distribution on the soil surface. Background technique [0002] The rapid measurement of some elements in soil is of great significance. On the one hand, the determination of element content in soil is inseparable from resource exploration and archaeological research. Rapid and accurate determination can provide powerful tool support for the study of geological changes and element migration rules. On the other hand, the determination of nitrogen and other nutrient elements is of great significance to the development and utilization of soil nutrients. Soil nutrients are an important source of crop nutrition. The measurement of nitrogen in farmland soil can help guide scientific fertilization. Therefore, it is of great scientific value and application value to quickly measure nitrogen on the soil surface and o...
