Application of leaf area measurement in agriculture

The size of leaf development and the size of leaf area have a great influence on crop growth, stress resistance, and yield formation. It is a necessary consideration for physiology, biochemistry, genetic development, crop cultivation, etc., as well as development of crop jihad, yield formation, The important indicator of breed characteristics. At the same time, the area size directly determines the strength of photosynthesis, but also reflects the use of solar energy, the most basic source of energy. It is also possible to increase the water use efficiency of green plants by adjusting the leaf area, and also to have a certain ability of absorbing fertilizer. It can be seen from the above that the leaf area measurement is still necessary.

Now to introduce a leaf area measurement method: leaf area detector method.

The leaf area detector, also known as the leaf area meter, is a tool that can measure leaf area and related parameters of the blade accurately, quickly and without damage. The leaf area detector measures the area of ​​harvested plant leaves and other sheet objects. The surface area of ​​the blade can be measured for any irregular shape, any color, any thickness and moisture content. The small leaves are placed directly on the measurement, and the large area of ​​the leaves is calculated on the slice. Finally, the average value is obtained.

Its measurement method is: After the leaf area detector first warms up and enters the normal measurement state, the user only uses the light emitting plate of the instrument to open, and the measured blade is tiled in the center of the photosensitive plate. Close the luminous plate cover, the system will automatically measure the surface area of ​​the tested blade, and save the area value on the instrument LCD display.

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