Embodiment 1

[0037] figure 1 It is a schematic flow chart of the method for measuring the anthocyanin content of purple corn leaves provided in Example 1 of the present invention. Such as figure 1 Shown, the measuring method of this purple corn leaf anthocyanin content comprises the steps:

[0038] 101. Collect the first hyperspectral reflectance corresponding to different wavelengths of purple corn male leaves in the sample, and collect the second hyperspectral reflectance corresponding to different wavelengths of the first-generation purple corn leaves in the sample.

[0039] Several days after the purple corn was sown, several leaves of the male parent of the purple corn and the leaves of the first generation of purple corn were collected as samples. The hyperspectral reflectance corresponding to different wavelengths of each sample was collected from the male leaves of purple corn, and the hyperspectral reflectance corresponding to different wavelengths was called the first hyperspec...

Embodiment 2

[0062] Figure 4 It is a schematic flow chart of the method for measuring the anthocyanin content of purple corn leaves provided in Example 2 of the present invention. Such as Figure 4 Shown, the measuring method of this purple corn leaf anthocyanin content is on the basis of embodiment one, also includes:

[0063] 201. Collect the hyperspectral reflectance of purple corn leaves to be verified at sensitive wavelengths.

[0064] Several parts of purple corn leaves were collected as samples to be verified, and the hyperspectral reflectance of purple corn leaves at sensitive wavelengths was collected from the samples to be verified. In order to ensure the accuracy of model verification, it is better not to collect the sample to be verified here to be the same as the sample in step 101 .

[0072] Figure 5 It is a schematic flow chart of the method for measuring the anthocyanin content of purple corn leaves provided in Example 3 of the present invention. Such as Figure 5 Shown, the measuring method of this purple corn leaf anthocyanin content is on the basis of embodiment one, also includes:

[0073] 301. Collect the hyperspectral reflectance of the purple corn leaves to be tested at sensitive wavelengths.

[0074] Several parts of purple corn leaves are collected as samples to be tested, and the hyperspectral reflectance of purple corn leaves at sensitive wavelengths is collected from the samples to be tested.

[0075] 302. Input the hyperspectral reflectance corresponding to the purple corn leaves to be tested into the anthocyanin content test model, and output the anthocyanin content of the purple corn leaves to be tested.

[0076] 303. Determine the anthocyanin content in the grain according to the predetermined corresponding relationship between the ant...

Abstract

The invention provides a method for measuring the anthocyanin content of purple corn blades, and a system thereof. The method comprises the following steps: acquiring the first hyperspectral reflectivity of the purple corn blades in samples at different wavelengths, and acquiring the second hyperspectral reflectivity of first generation purple corn blades in the samples at different wavelengths; determining the anthocyanin content of the first generation purple corn blades; carrying out addition operation on the first hyperspectral reflectivity and the second hyperspectral reflectivity; determining the wavelength corresponding to the strongest correlation in a correlation curve corresponding to the above operation result as a sensitive wavelength; and establishing an anthocyanin content test model according to the anthocyanin content, the sensitive wavelength, the addition hyperspectral reflectivity corresponding to the sensitive wavelength and the anthocyanin content of the first generation purple corn blades. Data adopted for modeling comprises the sensitive wavelength, the addition hyperspectral reflectivity corresponding to the sensitive wavelength and the anthocyanin content of the first generation purple corn blades, so the anthocyanin content obtained through modeling in the above mode is accurate.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method and system for measuring the anthocyanin content of purple corn flower leaves. Background technique [0002] Purple corn is an ancient corn variety from the Andes Mountains in America. Unlike traditional corn, the purple corn harvest includes purple corn kernels and leaves. Purple corn appears purple on both its leaves and kernels, and this vibrant color is produced by a class of substances called anthocyanins. [0003] A commonly used method for detecting anthocyanin content is the hyperspectral method. This method calculates the anthocyanin content by inverting the hyperspectral data of the sample. It is a fast and non-destructive detection method. Purple corn harvesting for decision making. [0004] However, the accuracy of this kind of hyperspectral modeling is relatively low, and the measured anthocyanin content is not accurate. Contents of the invention [0005] The...
