Application of leaf area measurement in agriculture

Leaf development size and leaf area have great influence on crop growth, stress resistance and yield formation. It is an essential consideration for research on physiological and biochemical, genetic development, crop cultivation, etc. It is also the development of crop jihad, yield formation, An important indicator of the characteristics of the variety. At the same time, the size of the area directly determines the strength of photosynthesis, but also reflects the use of solar energy. It is also possible to improve the water use efficiency of green plants by adjusting the leaf area, and also has a certain ability to absorb fertilizer. From the above, it can be seen that the leaf area measurement is still necessary.

Now let's introduce a method of measuring the leaf area: the living leaf area measuring method.

The living leaf area measuring instrument, also called the leaf area meter, is a tool that can measure the leaf area and related parameters of the blade accurately, quickly and without damage. The JMJ-A Living Leaf Area Analyzer can measure the area of ​​picked plant leaves and other sheet-like objects. The surface area of ​​the blade can be measured for any irregular shape, any color, any thickness and moisture content. The small blades are placed directly for measurement, and the large blade area is sliced ​​and finally averaged.

The measuring method is as follows: after the portable blade surface area measuring instrument is warmed up to the normal measuring state, the user only opens the illuminating plate of the instrument, and the measured blade is laid flat at the center of the photosensitive plate. When the illuminating plate cover is closed, the system will automatically measure the surface area of ​​the measured blade and store its area value on the LCD of the instrument.

The measurement of leaf area is necessary. By adjusting the leaf area, the water utilization rate can be improved, the overall fertilizer utilization rate can be finally obtained, and the high yield can be obtained. At the same time, it can also have an important reference for the accurate estimation of the disease and the reasonable financial protection measures. value.
