Embodiment Construction
[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0020] like figure 1 As shown, the chlorophyll fluorescence imaging system for on-line diagnosis and classification of crop diseases in the present invention includes: manipulator 1, computer 2, dark adaptation chamber 3, conveyor belt 4, chlorophyll fluorescence imaging chamber 5, sensor 6, LED light source board 7, CCD lens 8 and sample lifting table 9.
[0021] The manipulator 1 transfers the crops from the greenhouse to the conveyor belt 4, and transports them to the dark adaptation room 3 via the conveyor belt 4 for a period of dark adaptation, and then continues to be transported by the conveyor belt 4 to the chlorophyll fluorescence imaging room 5 connected to the dark adaptation room 3, That is, the online ...

The invention discloses a chlorophyll fluorescence imaging system and a chlorophyll fluorescence imaging method for diagnosing and grading crop diseases. The chlorophyll fluorescence imaging system comprises a dark adaptation unit, a chlorophyll fluorescence imaging unit, and an automatic conveying unit; a dark adaptation room communicates with a chlorophyll fluorescence imaging room, and crops get into the dark adaptation room to undergo dark adaptation; the crops arrive in the imaging room, a carrying platform can convey a plant in parallel to the position of a measuring center, and a roundtable on the carrying platform can also rise, lower and rotate the plant according to the height of the plant until the plant arrives at an appropriate measurement position; the plant is detected by the chlorophyll fluorescence imaging room in real time, an experimental program can be set to carry out automatic circulating measurement, imaging data are automatically stored into a computer and on-line data analysis is carried out, and according to three parameters among measured chlorophyll fluorescence kinetic parameters, i.e. photochemical quantum efficiency Fv / Fm, photochemical quenching coefficient qP and non-photochemical quenching coefficient qN, the computer diagnoses whether the crops are infected, and grades the diseases of the infected crops.
Description
technical field [0001] The invention relates to crop chlorophyll fluorescence imaging technology, in particular to a chlorophyll fluorescence imaging system and method for online diagnosis and classification of crop diseases. Background technique [0002] Crop diseases and insect pests are important factors affecting crop quality and yield. Crop diseases and insect pests often have the characteristics of outbreaks, destructiveness and suddenness, and are the main biological disasters in agricultural production in my country. There are many types of crop diseases, great impact, and strong disasters. While leading to a decline in the yield and quality of agricultural products, it will also cause a large amount of investment in pesticides and an increase in control costs, thereby increasing agricultural production costs and causing serious environmental pollution. Therefore, the prevention and control of plant diseases and insect pests in crops is the leading factor to maintain...
