Mass rapid measurement method for irregular leaf areas

Abstract

The invention discloses a mass rapid measurement method for irregular leaf areas. The measurement method comprises four steps; 1, samples are manufactured and selected; 2, areas and weights of the selected samples are tested; 3, a standard curve for the leaf areas and the leaf weights is built; and 4, the batch of single-grade leaf areas is tested in a mass mode. The method is used for mass rapidmeasurement on the irregular leaf areas.

Description

Technical field: [0001] The invention relates to a method for rapidly measuring the area of ​​irregular blades in large batches. Background technique: [0002] In the production of the tobacco industry, the sheet shape requirements for threshing and redrying enterprises are becoming more and more stringent; leaf area is an objective measure of "sheet shape", but this measure is based on statistical significance, which means that a large number of leaf area data. The tobacco raw materials used by rebaking enterprises and cigarette enterprises are different from other living plant leaves in that almost all tobacco leaves are wound and folded, and each piece must be carefully unfolded when measuring. [0003] In actual work, commonly used instruments or methods (leaf area meter, copy paper method, digital image analysis method, photoelectric panel method, etc.) can measure or calculate the leaf area more accurately, which is suitable for accurate measurement of a small amount ...

AI Technical Summary

Problems solved by technology

However, because the operation is too cumbersome (every piece of wrapped and folded tobacco leaf must be carefully unfolded), it is time-consuming and labor-intensive

In actual work, the required measurement materials are generally more, which takes a lot of manpower and time, and often makes mistakes (testers tend to expand the tobacco leaves insufficiently after repeated "boring" work for a long time)
