Instrument introduction
Plant canopy image analyzer is also called plant canopy analysis system. Plant canopy analyzer can measure leaf area index, average leaf inclination, scattered radiation transmittance, direct radiation transmittance under different solar altitude angles, and different suns. Extinction coefficient at altitude, azimuthal distribution of leaf area density, photosynthetically active radiation (PAR) inside and outside the canopy, etc.
The plant canopy image analyzer is widely used in the measurement and analysis of the canopy light conditions of crops and plant populations, as well as in agricultural and forestry scientific research.
Features:
1. The plant canopy image analyzer non-destructively measures the leaf area index, the average leaf inclination angle and the canopy structure;
2. The probe is small in size and can be installed on the measuring bar to measure the canopy structure of plants at any angle;
3. The camera can automatically keep level;
4. USB interface, connect to the computer to view the image in real time during measurement, select the required image in real time and save it;
5. External large-capacity lithium battery, suitable for field work and long-term measurement;
6. Measure the different heights of the canopy to get the vertical distribution map of light transmittance and leaf area index within the population;
7. Equipped with special analysis software, with the function of selecting the required image area (the zenith angle can be divided into 10 areas, and the azimuth angle can be divided into 10 areas), which can shield the unreasonable canopy part and only analyze the effective image area. Make the measurement data more accurate.
