The invention discloses a plant growth information obtaining device based on near infrared spectra, which is characterized by the following: the light source of near-infrared luminescent diode is fixed in the detecting platform in connection with the pivoted arm of upper detector; the sealing rubber is fixed on the detecting platform; the optical lens and optical fiber are fixed in the rack with two receiving faces opposing; the rack connects the pivoted arm of lower detector; the pivoted arm of upper and lower detector hinges; the exit end of optical fiber connects the input end of photoelectric sensor, which is fixed in the detecting controller; the output end of photoelectric sensor connects the input end of amplifier; the device measures the growth information of plant leaflet surface, which marks the model to correct the growth information to reduce the environmental influence; the detecting darkroom is composed of detector and sealing rubber to improve the detecting progress and speed without the interference of external light source, which is fit for gathering the on-site plant growth information.
Description
technical field [0001] The invention relates to a device for acquiring plant growth information, in particular to a device suitable for fast and online plant growth acquisition based on near-infrared spectrum analysis technology in protected agriculture. Background technique [0002] Driven by the national factory agriculture project, my country's facility agriculture has developed rapidly. At present, my country's facility agriculture area ranks first in the world, but the overall level still needs to be greatly improved compared with the world's facility agriculture developed countries. As the development trend of facility agriculture in the world, the core of factory agriculture is to effectively control the cultivation environment in the facility, carry out mechanized and automated production, and create the best environmental conditions suitable for crop growth. The computer intelligent control device uses sensors with different functions The detection head accurately ...
