Embodiment 1
[0064] Detection steps for detecting three-dimensional light distribution at multiple points on plant leaves:
[0065] 1. Turn on the power of the halogen light source 20, place the blade fixed value on the experimental platform 7, and move the light source rocker 16 to measure the zenith angle φ i=0° value, and use the wing nut to fix its position, adjust the second lens group to the position of the experimental platform 7, adjust the aperture 1906 and then adjust the uniformity of the intensity of the light source spot 24. Remove the leaves from the experimental platform 7 and store the leaves at low temperature. Connect the QE65000 spectrometer 10-1 and QE65000 spectrometer 10-2 with the QE65000 data cable to the computer to make it in working condition. It takes 30 minutes to make the light source system and the spectrometer system work stably. state.
[0066] 2. Set the incident angle of the light source on the computer software to be (φ i = 0°, Ψ i =0°), set the detec...
Embodiment 2
[0078] Detection steps for detecting the three-dimensional light distribution of plant leaves:
[0079] 1. Repeat Step 1, Step 2, Step 3, Step 4, Step 5, Step 6, and Step 7 in Example 1.
[0080] 2. Repeat step 4, step 5, and step 6 in Example 1, and the collected light is collected by QE65000 spectrometer 10-1 and recorded in the computer.
Embodiment 3
[0082] Detection steps for detecting the three-dimensional transmitted light distribution of plant leaves:
[0083] 1, repeat step 1, step 2 in embodiment 1,
[0084] 2. Set the incident angle of the light source in the computer software to be (φ i , Ψ i =0), at the same time, set the initial position of the detection direction of the receiving probe on the transmission receiving arc of the detection system (φ 2s始 , Ψ 2s始 )
[0085] 3. Adjust the Z-axis simple sliding table 24 so that the experimental platform 7 is at the lowest point in height, place the quartz vessel with a transmittance of 60% on the experimental platform 7 in step 1, and set and record the transmittance of 60%. The height H of the upper surface of the quartz vessel.
[0086] 4. Repeat steps 4, 5 and 6 in Example 1.
[0087] Remove the quartz vessel with a transmittance of 60%, fix the blade at the fixed position of the blade in step 1, and adjust the Z-axis simple sliding table 24 so that the height ...
