中文摘要:利用太赫兹衰减全反射技术,结合距离匹配算法,对不同品种花生进行快速分类鉴别。实验随机采集花育36号、鲁花1号和鲁花9号共3个花生品种、总计60个花生样本在0.3~3.6THz的太赫兹衰减全反射光谱,随后对其吸收系数进行一阶导数及归一化预处理,并建立花生品种的距离匹配快速鉴别模型。距离匹配模型结果显示:3个类别的总体识别准确率可达93.3%,仅有1个样本预测错误。研究结果表明,利用太赫兹衰减全反射技术实现花生品种快速鉴别具有一定的可行性,具有操作简单且快速高效等特点。

Abstract:Peanuts are rich in protein and lipids, which are widely cultivated in the north and south regions of China. As one of the main oil crops in China, the identification of peanut varieties is very important for breeding new varieties, improving oil production and processing quality. The commonly used detection methods such as experience identification, physical and chemical detection are all time-consuming and difficult to operate, could not meet the current rapid detection requirements well. So it is necessary to explore a rapid and efficient testing method for peanut varieties’ identification. Terahertz attenuated total reflection (THz-ATR) spectroscopy combined with distance matching algorithm (DM) were used to achieve the rapid identification of different varieties of peanut. A total of 60 peanut samples’ ATR spectrum in 0.3~3.6THz which included three varieties of peanuts: Huayu 36, Luhua 1 and Luhua 9 were collected randomly. Then the first derivative of ATR absorption coefficients were normalized to establish DM model and identify different peanut varieties rapidly. The final DM model result showed that the overall recognition accuracy of the three categories can reach 93.3%, with only one sample was misclassified. The research results showed that using THz-ATR to rapid detection and identification of peanut varieties had certain feasibility, and the method can be applied to other crop variety rapid identification and quality analysis because of its simpleoperation and efficient characteristics.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
