Abstract

The invention discloses a portable leaf area meter. The portable leaf area meter comprises a host; a monitoring plate, which can be pulled out / pushed in corresponding to the host, is arranged in the host; the monitoring plate is provided with a U-shaped monitoring groove for placing a sample leaf; a stamp box capable of printing regular ink dots on the corresponding part at the back of the sampleleaf is also arranged in the host; and an ink dot stamp is built in the stamp box. The portable leaf area meter in the invention is small in volume, light in weight, convenient to carry and use, and suitable for field work; the leaf does not need to be frequently contacted; and non-destructive local fine measurement on the leaf area of a plant is carried out.

Description

technical field [0001] The invention relates to a test device, in particular to a portable leaf area meter capable of measuring the local growth rate of a leaf, which monitors the change of the leaf area through the "color degree" of the pigment. Background technique [0002] Leaf area meter is an instrument for measuring the leaf area and related parameters of leaves, and it can also measure the area of ​​picked plant leaves and other sheet objects. It is widely used in agriculture, meteorology, forestry and other departments. Traditional leaf area meters need to sweep across the surface of leaves for measurement, and frequent contact with leaves will interfere with the normal growth of plants. Traditional leaf area meters are also unable to accurately track the changes in the growth of the detailed structure of each part of a single leaf during the entire growth period. Based on this consideration, this portable leaf area meter is designed. Contents of the invention ...
