Leaf area correction coefficient acquisition method for Tinospora crispa

Abstract

The invention discloses a leaf area correction coefficient acquisition method for Tinospora crispa. The leaf area correction coefficient acquisition method comprises the steps of S100, collecting leaves of Tinospora crispa as sample leaves; S200, measuring the length and the width of each sample leaf by adopting a leaf area analyzer measuring method, and measuring the length and the width of eachsample leaf by adopting a copying weighing method; S300, measuring the leaf area of each sample leaf by adopting the leaf area analyzer measuring method, and measuring the leaf area of each sample leaf by adopting the copying and weighing method; and S410, grading the sample leaves according to large, medium and small areas, and taking the leaf area of each sample leaf measured by the leaf area analyzer measuring method as a reference. According to the method, two leaf area measuring methods are adopted, the paired sample T test is performed on the obtained leaf areas according to the leaf size grade, two-factor (method and leaf size grading) variance analysis is performed on the length-width method correction coefficient calculated according to a scanning calculation method and a copyingweighing method, and the accuracy of the obtained correction coefficient is high.

Description

technical field [0001] The application relates to a method for obtaining a correction coefficient of a leaf area of ​​Pyrethium bonifolia, which belongs to the field of plant physiology and ecology. Background technique [0002] Leaf is the main organ of green plants for photosynthesis, and is one of the important symbols of the rationality of plant population structure, which has an important impact on biomass and yield. Establishing a convenient and accurate method for measuring leaf area is of great significance for modern agricultural production, estimation of net primary productivity (NPP) of vegetation, and estimation of plant yield. [0003] At present, the commonly used leaf area measurement methods include leaf area meter, planimeter, calculation paper method, image processing method, regression method, coefficient method, weighing method, graph decomposition method and parabola method. [0004] These methods have their own advantages, such as leaf area meter, imag...

AI Technical Summary

Problems solved by technology

[0007] Due to the special shape and irregularity of the leaves of Tinospora bonifolia, it is difficult to directly measure the leaf area

When measuring the leaf area of ​​the existing Tinospora bonifolia leaf area, the existing method has a cumbersome measurement process, and it is impossible to directly obtain the leaf area only by the value of the length and width of the leaf
