Plant leaves are important organs for plants to obtain nutrients and exchange energy. Therefore, the use of leaf area meters to conduct research on plant leaves is becoming more and more important for modern agriculture. Using the leaf area meter can quickly and accurately obtain the leaf area index of the plant. However, in order to ensure the safe use of the instrument and the superior performance of the leaf area meter and improve the accuracy of the measurement, it is necessary to pay attention to the following during the use of the leaf area meter. problem.
1. The leaf area meter can store the measurement data, and these measurement data are generally stored in the SD card. Therefore, in order to not affect the use, before using the leaf area meter, you need to first install the SD card, otherwise it is possible that the instrument is turned on. Has been in the welcome interface and can not enter the functional interface. If the SD card is lost, it can be purchased and replaced.
2. The leaf area meter automatically calculates the leaf area of ​​the blade by scanning the shaded area. Therefore, if the petiole or other part that does not belong to the blade enters the measurement area of ​​the leaf area meter, it is also counted back into the leaf area. There is a discrepancy between the size of the leaf area and the actual result. Therefore, before the measurement, the petiole should be removed. If it is a living body measure, care must be taken not to include the area of ​​the petiole.
3. The part of the leaf area meter that is in direct contact with the blade is mainly the glass surface of the instrument and the cover cushion. Therefore, in order to avoid the influence of the dirt on the blade on the performance of the instrument, keep the blade clean when measuring. Dirt and water droplets on the blade soiled the glass surface of the instrument and the cover cushion. This time it was necessary to clean it before continuing to make measurements. Otherwise, it may affect the measurement results.
The above is the place where the use of the leaf area meter needs attention. Since the leaf area meter is a highly sensitive instrument and is used more and more in modern agricultural research, in addition to operating and using in accordance with the specifications, in the ordinary We must also do a good job of maintaining and maintaining the instrument and keep the components of the instrument clean, so that the leaf area meter can play an important role in the process of use.
Flat packaging bags are a great choice for food packaging, powdered mixes, small products, and flat paper items. These bags could also been in sheet or in roll. With good grade material, nice heat sealing, the bags are water-proof and good for storage.
