Method and system for rapid identification of authenticity of seeds with seed coating agent

Abstract

The invention discloses a method and system for quickly identifying the authenticity of seeds with a seed coating agent, and relates to the technical field of seed authenticity identification. The method includes: S1: obtaining several seeds to be identified, and dividing each seed to be identified equally Divide it into two halves, and use each half as a unit to be identified; S2: Collect the near-infrared spectra corresponding to the sections of M units to be identified each time, and use the collected near-infrared spectra as the seeds to be identified S3: performing feature extraction on the near-infrared spectrum of the seeds to be identified, comparing the extracted features with a preset feature model, and determining the authenticity of the seeds to be identified according to the comparison results. The present invention collects the near-infrared spectrum of the cut surface of the seed to be identified by processing the seed to be identified, and realizes the identification of the seed to be identified according to the near-infrared spectrum, which not only realizes the authenticity identification of the seed by using the near-infrared spectrum, but also shortens the identification time .

Description

technical field [0001] The invention relates to the technical field of seed authenticity identification, in particular to a method and system for quickly identifying the authenticity of seeds with a seed coating agent. Background technique [0002] In recent years, the sale of counterfeit and shoddy seeds in the market has intensified, seriously damaging the interests of farmers. The state has strengthened the management of the commercial seed market, and the authenticity identification of seed varieties is an important part of supervision. Field planting identification is a widely recognized standard method, but it is time-consuming and labor-intensive; PCR-based DNA markers have achieved good results in crop quality control; DNA molecular marker fingerprinting methods (such as SSRS) have also been applied to The authenticity of the seeds is being verified. The above method requires high professional skills and experience of testing personnel, and consumes resources and t...

Problems solved by technology

The main components of seed coating agents are insecticides, fungicides, compound fertilizers, trace elements, plant growth regulators, slow-release agents, film-forming agents, etc., which provide necessary nutrients for seed germination and prevent the invasion of pests and diseases. Hydrogen-containing groups such as C-H, N-H, O-H of organic substances will absorb light in the near-infrared band, so it has a great impact on the near-infrared spectrum of seeds, making it impossible to use near-infrared spectroscopy to realize the authenticity of seeds
