Technical Field

[0001] The utility model relates to the technical field of leaf area index meters, in particular to a leaf area index meter suitable for vegetation growing in a ditch. Background Art

[0002] The Leaf Area Index (LAI) meter is an easy-to-use, field-ready instrument that accurately, quickly, and non-destructively measures leaf area and related parameters. It can also measure the area of ​​harvested plant leaves and other sheet-like objects. It is widely used in agriculture, meteorology, forestry, and other sectors.

[0003] It has the advantages of fast field non-destructive measurement, large data storage capacity, ability to measure leaf circumference, ability to download or browse graphics of the measured leaf area (BMP or TIF format), and ability to measure multiple leaf parameters: leaf area, average leaf area, leaf length, leaf width, and aspect ratio. However, in some locations with complex ditch terrain, the existing leaf area index meter on the market has a single lens structure that is not easy to adjust, and the detection angle cannot be flexibly adjusted. It is not suitable for complex terrain detection and has limitations in use. Therefore, we propose a leaf area index meter suitable for vegetation growing in ditch. Utility Model Content
