Crop seed variety authenticity identification method based on near infrared spectrum

Abstract

The invention discloses a crop seed variety authenticity identification method based on near infrared spectrum. The method comprises the following steps of 1, acquiring near infrared spectrum data of crop seed samples, and preprocessing the near infrared spectrum data which is taken as a training sample; 2, selecting the needed spectrum data from the preprocessed near infrared spectrum data, and establishing a qualitative analysis model of the crop seeds by a feature extraction method and a modeling method; and 3, carrying out variety authenticity identification on the spectrum of the crop seeds which are taken as test samples and about to be identified. The crop seed variety authenticity identification method is based on the near infrared spectrum, the general near infrared spectrum qualitative analysis model can be established by a series of operation such as spectrum preprocessing, feature extraction, modeling and identification, and the method is capable of rapidly and accurately identifying the crop seed variety authenticity.

Description

technical field [0001] The invention relates to the field of variety identification of crop seeds, in particular to a method for authenticity identification of crop seed varieties based on near-infrared spectrum. Background technique [0002] China is a big agricultural country, and agriculture is a strategic industry that secures the world and stabilizes people's hearts. "The country is based on agriculture, and agriculture is based on seeds." The safety of the seed industry is the premise of my country's food security and one of the prerequisites for agricultural security. However, my country's seed industry market is not optimistic, the infringement of varieties is serious, and incidents of counterfeit and inferior seeds pitting farmers and harming farmers occur from time to time. It is difficult for enterprises to defend their rights, to file lawsuits, and to recover compensation. As a result, many fine varieties have been infringed, so that it has become a strange phen...

AI Technical Summary

Problems solved by technology

[0004] All there are multiple technical barriers in the above methods: (1) identification time is long; (2) identification cost is high; (3) process is loaded down with trivial details; (4) identification person needs special technical knowledge; (5) identification needs specific test condition, chemistry Reagents, equipment, etc.

Therefore, the seed industry market lacks effective rapid on-site identification techniques and equipment, which brings many difficulties to agricultural production, management and law enforcement, and it is difficult to effectively guarantee seed safety and food security
