Abstract
The present invention relates to a measuring method for leaves of broad-leaved plants, which comprises the steps: the leaves of broad-leaved plants are collected and are scanned by a scanner according to the proportion of 100%; the areas of the leaves of broad-leaved plants are measured by combining AutoCAD software and Photoshop software, the average value is calculated after measuring a plurality of samples, and consequently, the areas of the leaves of tree species are reckoned up. The method is simple and convenient, enhances the calculating accuracy rate of the areas of the leaves, and provides an essential data collecting feasible scheme for the scientific research of the biology and the ecology of agriculture, forestry, etc.
Description
Technical field
The present invention relates to the determination techniques of blade of broadleaf plant, be specially and utilize scanner and AutoCAD software to measure the method for the leaf area of broad leaved plant in conjunction with Photoshop software.
Background technology
The mensuration of blade of broadleaf plant has many methods and instrument, people utilized usually on the square paper of fixed size blade were drawn by the type shape in the past, and then utilize its area that covers grid to calculate the area of blade, the method operation easier is bigger, calculate take a lot of work, time-consuming and error is bigger.Some scientific research apparatus research departments and company have made the instrument of multiple direct measurement leaf area at present, as " the portable leaf area instrument of CI-202 ", " Li-3300 leaf area analyzer " and homemade " WDY-500A (300A) the type microelectronics area measurement instrument " of import.Though these instruments are more convenient, but its survey area is mostly less than normal, and costs an arm and a leg.
Summary of the invention
The economy, the simple method that the object of the present invention is to provide a kind of broad leaf plant leaf area to measure, this method used tool only is computing machine and scanner that general office space possessed, and simple and easy to do, calculate accurately.The feasible program that provides a kind of new basic data to collect for biology, ecological scientific researches such as farming, woodss.
Technical scheme of the present invention is:
A kind of assay method of blade of broadleaf plant after the blade of broadleaf plant collection, scans in 100% ratio with scanner; Measure its area with AutoCAD software in conjunction with Photoshop software then, ask its mean value after measuring a plurality of samples, thereby calculate the leaf area of seeds.
Gather blade of broadleaf plant, with scanner proportionally 100%, resolution 100-300dpi carries out black-and-white photograph scanning, the picture after the scanning saves as forms such as Jpg or Tiff.
Under the Photoshop software environment, open this width of cloth picture, click " image " button on the menu bar, on its drop-down menu, click " image size " button with left mouse button, find " constrain proportions " option in " the image size " launched in to picture frame, and on the choice box of its front, choose; Do not choose before the Resample Image option below; On the unit option of " width ", select " centimetre "; On the unit option of " length ", select " centimetre "; On the unit option of " resolution ", select " pixel/inch " input " 100 " under size options; Read and count record " image size " then to " width " numerical value in the picture frame.
Open AutoCAD software, on menu bar, click insertion → raster image, the picture dialog box occurs selecting, need to select the leaf image of survey area; Select selecting on the frame before the appointment of insertion point → on screen in below the image dialogue after the selection, select selecting on the frame before the appointment of scaling → on screen, before the appointment of the anglec of rotation → on screen, select on the frame and do not select, click confirming button.Click the mouse left button once in the screen lower left, upwards gently move mouse, make and select frame to be amplified within the screen visual range, click the mouse left button more once.Click the instrument → inquiry → distance terms on the menu bar, click left mouse button once, click left mouse button once at the upper right corner of picture end points again, will demonstrate the value of " distance " like this in the status bar below screen at the upper left corner of picture end points.Divided by this " distance " value, just obtained a scale factor with " width " value of determining among the Photoshop noted earlier.Click to revise the zoom button on the menu bar, outside picture, from left to right picture chosen, choose the back picture outside a mouse click right button once, a mouse click left button is once directly imported carriage return affirmation behind the scale factor with keyboard in picture then.Click multistage line button on the drawing menu bar, the blade in the picture is enclosed choosing, the circle choosing finishes back keypad C key → carriage return, it is enclosed the choosing sealing handle.Click instrument → inquiry → area → keypad O key (English the O) → carriage return on the menu bar, a mouse click left button in the circle route selection, at this moment will showing in the status bar below screen goes too far selects the area of blade.
Ask its mean value after measuring a plurality of samples with the method, thereby calculate the leaf area of seeds.
Advantage of the present invention and beneficial effect are:
1, but the present invention has overcome survey area (breadth of general scanner is all about the area of 19cm * 29cm) less than normal and expensive shortcoming in the prior art, the accuracy rate that this method is simple, convenient, the raising leaf area is calculated.
2, the inventive method used tool only is computing machine and the scanner that general office space possessed, by Photoshop software and the AutoCAD software that is used, problems such as expensive, the limitation that has broken through traditional blade computing method and utilized that the leaf area analyzer brings, make measuring blade simple and easy to do, calculate accurately.
3, the present invention's feasible program of providing a kind of new basic data to collect for biology, ecological scientific researches such as farming, woodss.

Embodiment
Embodiment 1
A kind of assay method of blade of broadleaf plant, gather 20 pieces in the blade of a kind of broad leaved plant false color maple (Acerpseudo-sieboldianum), with scanner proportionally 100%, resolution 300dpi carries out black-and-white photograph scanning, picture after the scanning saves as the Jpg form, resolution 300dpi effect is that picture clarity is increased, and measures digitized accuracy rate to improve the blade face.
Under the Photoshop software environment, open this width of cloth picture.Click " image " button on the menu bar.On its drop-down menu, click " image size " button with left mouse button.Find " constrain proportions " option in " the image size " launched in to picture frame, and on the choice box of its front, choose; Do not choose before the Resample Image option below; On the unit option of " width ", select " centimetre "; On the unit option of " length ", select " centimetre "; On the unit option of " resolution ", select " pixel/inch " input " 100 " under size options; Reading and count record " image size " then is 11.38cm to " width " numerical value in the picture frame.More than " image size " see shown in Figure 1 to the operation in the picture frame.
