Embodiment 1

[0038] Example 1 Establishment of regression model

[0039] The establishment of partial least squares regression model of sugar beet quality detection index and near-infrared characteristic wavelength spectrum is as follows:

[0040] 1. Collect a total of 380 samples of 28 varieties of sugar beet, and put them in a sample bag after being sawed and paste.

[0041] The sample will be pretreated (see figure 2 ) The beet saw paste samples are evenly spread in a sample cup with a diameter of 75mm, and scanned 60 times with a resolution of 5nm using a near-infrared analyzer. The temperature of the sample and the environment are both 20±2℃, and the spectral scanning range is 900~1700nm. , Get the near-infrared scanning spectrogram, see the original picture image 3 . Repeat the sample loading measurement twice to maintain the uniformity of the sample loading and obtain the average spectral curve.

[0042] 2. Perform the first derivative (FD), standard normal variable transformation (SNV),...

Embodiment 2

[0045] Example 2 Quality inspection of samples to be tested

[0046] Based on the regression model established in Example 1, quality testing and grading of 70 samples to be tested were performed, and the steps were as follows:

[0047] 1. Pretreatment of the sample to be tested (e.g. figure 2 );

[0048] 2. Spectral scanning of the sample to be tested by the near-infrared analyzer;

[0049] 3. The test results of the sugar content index of the sample to be tested are shown in Table 1.

[0052]

[0053] One-way analysis of variance results P = 0.9549, r = 0.9599, SEP = 0.439, Bias = 0.023

[0054] From the above analysis results, it can be seen that there is no significant difference between the predicted value of the near-infrared sugar content model and the laboratory true value (P = 0.9549), the correlation between the two sets of data is goo...

Embodiment 3

[0055] Example 3 Establishment of a near-infrared detection model for large sugar beet particles

[0056] The establishment of partial least squares regression model of sugar beet quality detection index and near-infrared characteristic wavelength spectrum is as follows:

[0057] 1. A total of 115 representative sugar beet samples were selected, and they were made into large sugar beet particles and then packed in a sample bag for uniform numbering, and spectral scanning was used for standby.

[0058] Obtaining large beet particles: clean the beet sample, remove the leaf crown, and evenly cut it into 2mm*2mm*2mm particles. Spread the sugar beet particle sample evenly in a sample cup with a diameter of 75mm, and use a near-infrared analyzer to scan 60 times with a resolution of 5nm. The temperature of the sample and the environment are both 20±2℃, and the spectral scan range is 900~1700nm. A near-infrared scan spectrum is displayed. Repeat the sample loading measurement twice to mai...

Description

Technical field [0001] The invention relates to a rapid detection method for sugar beet quality, and belongs to the technical field of agricultural product quality detection. Background technique [0002] For a long time, due to the limitation of traditional analysis technology, the raw material purchasing system based on the quality-based price has not been established in my country's sugar companies, and the raw material purchasing has been priced by weight. Growers blindly pursue high yield, light quality, and low-quality raw materials greatly increase the consumption of sugar factories. Therefore, it is of great significance to realize the rapid detection of sugar beet quality and price evaluation by quality. [0003] The quality of beet has an important influence on the sugar yield, especially the sugar content index. Sugar beet sugar content can significantly affect the efficiency and economic benefits of sugar production by sugar companies. At the same time, the realizatio...
