Description
Technical field
This utility model relates to Agricultural Information monitoring technical field, particularly to a kind of leaf area index observation device.
Background technology
Leaf area index is again leaf-area coefficient, is the gross area of crop leaf and the ratio of floor space on plot.
Leaf area index is one of key parameter in ecological study, relies primarily on the Instrument measuring such as LAI-2000, fisheye camera, this
The Leaf area determination principle of quasi-instrument is all based on miller law and Bell's law, owing to being affected by branch and leaf overlap, measures
Leaf area index the most on the low side compared with true leaf area index, for effective leaf area index, there is certain error, it is accurate
Rate is low.Using harvest method to measure leaf area true, but labor intensity is big, efficiency is low, welding, it is difficult to recover.
Mostly existing conventional leaf area index measuring method is to use camera or scanner that leaf image is recorded
After, then it is sent to computer, extract blade area ratio by Photoshop, then manually calculate in conjunction with agronomic parameters.
Automatical and efficient measurement can not be realized and calculate leaf area index.
