Problems solved by technology

[0003] The purpose of the present invention is to: overcome the defects that when the original visible spectrum or liquid chromatography method is used to measure the pigment content in plant leaves, the measurement speed is slow, the measurement process needs to consume reagents, and also produces waste liquid and pollutes the environment. ; more importantly, the defects that cause damage to crop leaves when measuring the pigment content in plant leaves; in order to realize the non-destructive detection of the content of pigment in crop leaves in the field growth process; thus providing a multi-wavelength correction for scattering and background removal System and method for portable non-destructive detection of field plant pigments for non-destructive detection of pigment content in crop leaves

Abstract

The portable non-destructive plant pigment detecting system includes three wavelength spectral measurement device with oppositely set light source and detector, neutralized reference sample or leaf to be measured, micro controller connected to the light source and the detector, serial port circuit connected electrically to the micro controller, and display and keyboard connected electrically to the micro controller too. The detection method includes detecting data I0 and I, calculating the fresh leaf transmission T= I / I0 of different wavelengths, and calculating the plant pigment content ChI in the leaf in chemical metering algorithm. Compared with traditional wet chemical method, the present invention has decades times raised efficiency and no production of environment harming matter.

Description

technical field [0001] The invention relates to a plant pigment detection system, in particular to a portable nondestructive detection system and method for field plant pigments. Background technique [0002] The content of pigments (including total chlorophyll, chlorophyll A, chlorophyll B, carotene, etc.) in plant leaves can reflect crop growth, nutrition, pests and diseases, etc. Based on this, suggestions can be made for crop cultivation management, especially for agricultural development. important meaning. As described in literature [1] Yan Yanlu, Liu Xinsheng, "Research on Chlorophyll Determination Method", Journal of Beijing Agricultural University, 8 (2), P53~66, 1982: the content of existing crop pigments needs to be detected by visible spectrum or liquid chromatography Before the determination, it is necessary to extract the relevant pigments in the leaves of the crops by wet chemical methods, and then separate or measure them. These determination methods are not...
