Embodiment 1

[0025] On December 20, 2017, a well-growing Scherichia radiata ( Schefflera microphylla ), randomly picked a mature leaf with no pests and diseases and no obvious defects in the sunny place in the middle of the canopy, and quickly brought it back to the laboratory for use.

[0026] Open the platen cover of the scanner, place the leaves on the platen glass with the front facing down and the tip of the leaves facing the scale, with the distance between each leaf > 1cm, close the cover; Settings, such as output type color or grayscale, resolution 300dpi, scan size of the entire scan area, image format JPEG, file save path and file name, click the "Scan" button, after the scan is completed, the image file will be automatically saved to the specified folder middle.

[0027] Double-click the Adobe Photoshop image processing software shortcut icon on the desktop to start the application, execute the "File / Open" command, and an open dialog box will pop up, select the leaf image file...

Abstract

The invention discloses a method for determining the plant leaf area based on Photoshop software. The method comprises the following steps: acquiring a leaf image by using a scanner and determining the plant leaf area by using the Photoshop image processing software. The method disclosed by the invention has the benefits that the leaf image is acquired by using the scanner so as not to be influenced by an external environment; the image is clear, adopts 1:1 reduction and is free from deformation; and as the plant leaf area is determined by using the Photoshop image processing software, manualdata recording and measurement result calculation are not required in the process, and a program is used for automatic measurement according to the set measurement ratio. The method is simple and quick, the amount of information is large, the measured data includes four indexes: leaf area, perimeter, height and width and is not influenced by leaf shape, size, color, thickness and exterior, and measurement results are accurate; and the method is rigorous in science, low in cost, widely applicable to the determination of the areas of various plant leaves and wide in application prospect.

Description

technical field [0001] The invention belongs to the field of plant physiological ecology research, and relates to a method for measuring plant leaf area based on Photoshop software. Background technique [0002] Leaf is the main organ for material and energy exchange between plants and the external environment, and plays a vital role in the function of terrestrial plant ecosystems. Leaf traits are the internal physiological and external morphological adaptation strategies formed by leaves in response to environmental changes. meaning of biological evolution. Leaf traits can be divided into two categories: functional traits and structural traits. Functional traits reflect the growth and metabolism indicators of leaves, and their variation with time and space is relatively large, so it is difficult to explain the adaptation mechanism of plants in the long-term evolution process. Structural traits refer to the biochemical structural characteristics of leaves, mainly includin...
