Abstract

The invention relates to a portable system for rapidly recognizing chemical fertilizer, which comprises a computer terminal, a Raman spectrometer and a database server, wherein the computer terminal is respectively connected with the Raman spectrometer and the database server; standard spectrogram data are set in the database server; the Raman spectrometer collects Raman spectrogram data of to-be-detected samples and transmits the Raman spectrogram data to the computer terminal; and the computer terminal compares the collected Raman spectrogram data and the standard spectrogram data in the database server to recognize the chemical fertilizer. Compared with the prior art, the portable system has the advantages of wide application range, high measurement accuracy, high measurement efficiency, and the like.

Description

technical field [0001] The invention relates to a chemical fertilizer identification system, in particular to a portable quick identification system for chemical fertilizers. Background technique [0002] Fertilizer is a class of substances that provide one or more essential nutrients for plants, improve soil properties, and increase soil fertility. One of the material basis of agricultural production. As early as the Western Zhou Dynasty, China already knew that field weeds can promote the growth of millet after they rot. "Qi Min Yao Shu" introduces in detail the method of planting green manure and the method of crop rotation between leguminous crops and gramineous crops; it also mentions the method of using crop stalks mixed with cow dung and urine, trampling and composting to make fertilizer . The authenticity of fertilizers is an important factor affecting crop growth and is closely related to the interests of farmers. [0003] Usually, it is only to use some simple ...
