Method and system for rapidly identifying authenticity of seeds with seed coatings

Abstract

The invention discloses a method and a system for rapidly identifying the authenticity of seeds with seed coatings, and relates to the technical field of seed authenticity identification. The method comprises the steps of S1, acquiring a plurality of seeds to be identified, and cutting each seed to be identified into two equal halves, wherein each half is taken as a unit to be indentified; S2, acquiring near-infrared spectrums corresponding to the cut surfaces of the M units to be indentified every time, wherein the acquired near-infrared spectrums are taken as near-infrared spectrums of the seeds to be identified; and S3, carrying out feature extraction on the near-infrared spectrums of the seeds to be identified, comparing extracted features with a preset characteristic model, and determining the authenticity of the seeds to be identified according to the comparison results. According to the method and the system, the seeds to be identified are treated, the near-infrared spectrums of the cut surfaces of the seeds to be identified are acquired, and the seeds to be identified can be identified according to the near-infrared spectrums, so that the authenticity of the seeds can be identified by the near-infrared spectrums, and the identification time is short.

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
