The embodiment of the invention provides a plant leaf amino acid content detection method and device. The method comprises the steps of obtaining the reflectivity of a preset waveband of to-be-detected amino acid according to a hyperspectral image of a plant leaf, inputting the reflectivity of the preset waveband into a preset amino acid content detection model for the to-be-detected amino acid for calculation, and obtaining the content of the to-be-detected amino acid according to a calculation result, the amino acid content detection model being obtained by fitting according to a hyperspectral image sample with known amino acid content. According to the method, the reflectivity of the preset waveband of the to-be-detected amino acid is obtained through the hyperspectral image, sample processing is simple, efficiency is high, and cost is low. The reflectivity of the preset waveband is inputted into the amino acid content detection model preset for the to-be-detected amino acid for calculation to obtain the content of the to-be-detected amino acid, so that rapid detection of various amino acids can be realized, and the method has the characteristic of high flux.
Description
technical field [0001] The invention relates to the field of crop detection, in particular to a method and device for detecting amino acid content in plant leaves. Background technique [0002] Amino acid is the basic unit of protein, and the nitrogen absorbed and assimilated by plants through the root system is mainly transported in the form of amino acid. Amino acids closely link the absorption and assimilation of nitrogen in plants with the synthesis and degradation of proteins in organs, and also undertake the transfer role of nitrogen redistribution between sources and sinks. In addition, different amino acids have different physiological functions on plants. Therefore, the quantitative analysis of various amino acids in the leaves of plants (crops) plays an important role in the genetic research and breeding of plants (crops). [0003] At present, the commonly used amino acid determination methods mainly include: chemical analysis, spectrophotometry, mass spectrometr...
