The leaf is the main vegetative organ of the plant. The photosynthesis and transpiration of the leaf directly affect the growth of the plant, which is crucial to the survival of the plant, and it is related to the level of the yield of the crop and the quality. Accurately measuring the leaf area can help us quickly understand the leaf development and leaf area growth regularity, the relationship between photosynthesis and water content of leaves, the ratio of leaf and fruit as well as the development of a reasonable cultivation program, the plan of pruning and fertilization, and it has important guiding significance. There are many methods for measuring leaf area, but there are many ways to measure leaf area. Some methods are cumbersome and affect the normal growth and biomass of plants. Here's a quick method to measure leaf area. Measured using a leaf area meter.

Leaf area meter is a leaf area detection instrument that can be measured in the field. It can be used to quickly measure living plant leaves and obtain parameters such as leaf area, perimeter, accumulated area, and average area. It has the characteristics of simple operation, fast response, high analysis accuracy and easy maintenance. The leaf area meter can be widely applied to scientific research of plant physiology and ecology. It can be applied to the cultivation and breeding of crops, forest trees, flowers, fruit trees and vegetables, and is essential for plant research.

The leaf area meter can measure the area of ​​plant leaves and other sheet objects that are growing and (non-contact scanning, no damage to the foliage). The surface area of ​​the blade can be measured for any irregular shape, any color, any thickness and moisture content. Measuring speed, you can measure multiple leaves at once. Automatic measurement of area perimeter. Living Leaf Area Meter / Leaf Area Meter Function: Automatic measurement of blade surface area: The system will automatically measure the surface of the blade under test. Multiple leaves can be measured at one time. Automatic measurement of area perimeter.

The main process of detection by the leaf area meter is to measure the leaf area of ​​the plant by using the leaf area meter, and then to calculate the length of the leaf, the width of the leaf, and the length-width product of the leaf. The leaf area meter has a function: with a computer interface, data viewing is no longer limited to viewing on the host computer, but can also be uploaded to the computer for further viewing, and a data analysis software corresponding to the instrument at the same time. The software can be printed and converted into EXESEL format.

The data obtained from the leaf area analyzer was subjected to regression analysis using EXCEL software. The results show that the best relationship between leaf area and leaf length is a power function, so that the initial regression equation is used to perform further calculations through regression equations. The leaf area will be smaller, and the error will be smaller. A linear regression equation using leaf area and length-width product, a linear regression equation for leaf area and leaf width, and a linear regression equation for leaf area and leaf length are used to compare the results to arrive at the most accurate measurement method. The exact method for plants is The Linear Regression Equation of Leaf Area and Product of Length and Breadth . By using it for conversion, the total leaf area of ​​the plant can be obtained, saving a lot of time.
