[0002] To better understand crop growth, it is often necessary to conduct regular canopy spectral observations of crops in experimental fields. However, traditionally, when conducting canopy spectral observations of crops, staff members often need to manually move the calibrator above the experimental field to be observed. This method is cumbersome and has low observation efficiency. Existing technologies also include setting up calibrators independently in each experimental field. This method requires a large number of spectrometers and is costly.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figure 1 and Figure 2 ,in Figure 1 A schematic diagram of a preferred embodiment of the fully automated vegetation canopy spectral auxiliary observation device for field experimental observation provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the support frame. The fully automated vegetation canopy spectral auxiliary observation device for field experimental observation includes: a spectrometer 1 and a support frame 6. The spectrometer 1 is connected to one end of a bifurcated optical fiber 2. The other two ends of the bifurcated optical fiber 2 are respectively connected to a first corrector 7 and a second corrector 8. An electronic switch 3 is provided on the bifurcated optical fiber 2. The first corrector 7 and the second corrector 8 are both on the support frame 6, with the first corrector 7 located directly below the second corrector 8.

[0019] It also includes an insulated box 5, in which the spectrometer 1 and the electronic switch 3 are both located.

[0020] It also includes a controller 4, which is connected to the spectrometer 1.

[0021] The first corrector 7 is set vertically downwards and is used to collect the radiation reflected upwards from the crop canopy in the field, with a field of view of 25°; the second corrector 8 is set vertically upwards and is used to collect the downward solar radiation within a 180° field of view.

[0022] The bracket 6 includes a base 601, a first support seat 602 rotatably mounted on the top of the base 601, a first hydraulic rod 603 fixedly mounted on the top of the first support seat 602, a second support seat 604 fixedly mounted on the top of the first hydraulic rod 603, a second hydraulic rod 605 fixedly mounted on one side of the second support seat 604, a mounting plate 606 fixedly mounted on the output shaft of the second hydraulic rod 605, and a mounting base 607 fixedly mounted on the mounting plate 606. The first calibrator 7 and the second calibrator 8 are both mounted on the mounting base 607.

[0023] The first hydraulic rod 603 is used to vertically adjust the height of the first corrector 7 and the second corrector 8 to adapt to the height of the crops in the experimental field;

[0024] The second hydraulic rod 605 is used to adjust the horizontal position of the first corrector 7 and the second corrector 8 so that the first corrector 7 and the second corrector 8 are located in the center of the test field.

[0025] The bracket 6 can be set at the center of the intersection of two or more experimental fields, so that when the mounting base 607 rotates around the second hydraulic rod 605, it can be moved to the top of any experimental field as needed to conduct vegetation canopy spectral observation.

[0026] A motor 609 is fixedly installed on the top of the base 1. A first gear 610 is fixedly installed on the output shaft of the motor 609. A second gear 611 is fixedly sleeved on the outer side of the first support 602. The first gear 610 meshes with the second gear 611.

[0027] By setting up the motor 609, the first gear 610 and the second gear 611, the first calibrator 7 and the second calibrator 8 can rotate 360° around the first hydraulic rod 603 as the axis, thereby enabling automatic monitoring of multiple test fields.

[0028] In order to better monitor different experimental fields, the starting frequency and forward and reverse rotation of motor 609 can be controlled by timer to achieve the observation frequency of spectrometer 1 on the experimental fields, thereby enabling better observation of the experimental fields.

[0029] Fiber optic fixing seats 608 are fixedly installed on the first hydraulic rod 603, the second support seat 604, and the second hydraulic rod 605. The fiber optic fixing seats 608 are used to fix the branched fiber optic 2.

[0030] In this embodiment, one end of the electronic switch 3 is connected to the spectrometer 1 via a branched optical fiber 2 (the spectrometer can be replaced as needed), and the other end is connected to two optical fibers (the fiber type and length depend on the specific experimental conditions). A second corrector 8 (CC-3 cosine corrector) is installed at the end of one optical fiber, oriented vertically upwards to collect downward solar radiation within a 180° field of view. A first corrector 7 is installed at the other end to collect upward-reflected radiation from the canopy of field crops such as winter wheat or summer corn, with a field of view angle of 25°. The mounting height of the mounting base 607 on the specific support 6 depends on the specific crop and planting density, and the height of the crossbar can be adjusted in real time as the crop grows to ensure that the vertical distance between the crossbar and the crop canopy is at least approximately 2 meters. The length of the horizontal crossbar robotic arm can be adjusted in real time according to the experimental treatment area (normally around 2 meters, but overall stability and robustness must be considered) to ensure that different experimental treatment observation ranges are met.

[0031] Spectrometer models include: Ocean Optics QE pro spectrometer (wavelength: 640-800nm; maximum half-width (FWHM): approximately 0.35nm; signal-to-noise ratio: 1000:1) and fiber optic switches (Ocean Optics, Inc., Dunedin, FL, USA); HR2000+ spectrometer (wavelength: 680-770nm; maximum half-width (FWHM): approximately 0.13nm; Ocean Optics, Inc., Dunedin, FL, USA), etc.
