Abstract

The invention discloses a seed vigor determining method and system based on NIRS and a storage medium. The method comprises the following steps: obtaining an index component measured value according to sample seeds and original near infrared transmitted spectra of the sample seeds; pre-processing the original near infrared transmitted spectra of the sample seeds, including detrending and mean centralizing; determining a modeling method according to the index component measured value; constructing a PLSR model according to the pre-processed result based on the determined modeling method; and determining the seed vigor through the PLSR model. The PLSR model capable of predicting the seed vigor is established based on near-infrared reflectance spectroscopy, so that the seed vigor predicting speed is accelerated greatly and the seed vigor predicting accuracy is improved. In addition, a lot of detection equipment is not used, so that the cost is lowered. The method and system can be widelyapplied to the technical field of infrared analysis.

Description

technical field [0001] The invention relates to the technical field of infrared analysis, in particular to a method, system and storage medium for measuring seed vigor based on NIRS. Background technique [0002] Sweet corn is an important advantageous and characteristic crop in Guangdong Province and South China. It has the nutritional characteristics of both grain and fruit and vegetable crops, and also has the characteristics of good taste and low blood sugar food. It is the preferred crop for agricultural disaster relief in Guangdong. High seed vigor is an important quality trait of sweet corn seeds, and varieties with high vigor seeds have obvious growth advantages and yield-increasing potential, which is of great significance to agricultural production. [0003] With the rise of modern low-temperature storage, the lifespan of seeds can be greatly extended, but with the extension of storage time, seeds will age, resulting in decreased vigor and changes in physiological ...
