    摘要:

    为快速无损检测单粒种子成熟度,推进现代良种单粒播种技术,采用近红外光谱技术结合化学计量学方法建立了单粒玉米种子成熟度快速鉴别模型。采集200份单粒玉米种子样本近红外光谱,采用多种光谱预处理方法消除单粒种子采集过程中由于颗粒形态、杂散光等引入的干扰信息,分别采用分段谱区、连续投影算法筛选特征波长,优化建立种子成熟度判别模型。经SG5_1预处理后,在5500~4000cm-1谱区建立的基于支持向量机的单粒玉米种子成熟度判别模型的分类准确率可达92%。实验结果表明,近红外光谱技术可以快速无损判别单粒玉米种子成熟度。

    Abstract:

    Seed maturity is an important factor affecting seed quality and crop yield. Therefore, rapid nondestructive testing of single seed maturity is an important basic technical guarantee for promoting modern single seed sowing technology for improved seeds. A rapid identification model of single corn seed maturity was established by combining nearinfrared spectroscopy and chemometrics. The experiment collected the near infrared spectrum of 200 single corn seed samples. Interference information was reduced by particle morphology, stray light, etc. during single seed collection. The segmentation spectral region was used respectively, and the continuous projection algorithm was used to screen the feature wavelength optimization to establish a seed maturity determination model. The experiments showed that the recognition accuracy of the SVM based single corn seed maturity discrimination model established in the 5500~4000cm-1 spectral region could reach 92% after the Savitzky-Golay 5point convolution first derivative pretreatment. The results showed that NIR had a bright application prospect in the rapid and nondestructive discrimination of single corn seed maturity.
