The modern use of crop canopy analyzers can quickly obtain measured data, providing a lot of convenience for the conduct of various agricultural research experiments, which is not to be deeply understood by researchers and experts, and with the availability of crop canopy analyzers. The application has been praised by more and more people, and the number of applications of this instrument is also increasing. Therefore, in order to ensure that it can measure accurate and valid data, it is critical to properly grasp the use of crop canopy analyzers. At the same time, we must pay attention to some places that need special attention when measuring, to avoid measurement errors. So what do you need to pay attention to when looking at the crop canopy analyzer?
1. Pay attention to the distance between the blade and the sensor The crop canopy analyzer uses the sensor to measure. Therefore, during the measurement process, pay attention to the distance between the blade and the sensor, because too close will lead to measurement error. Therefore, it is necessary to clarify the distance between the blade and the sensor. If the distance cannot be reduced, consider increasing the number of repetitions to solve this problem.
2. Avoid direct sunlight. Direct sunlight may cause measurement errors. Therefore, direct sunlight should be avoided during measurement using a crop canopy analyzer. Generally, ideally, the weather is measured at sunrise, sunset, or cloudy. Weather, which covers the cap design, is also to reduce errors due to light, such as removing the sun from the sensor's field of view; removing the operator's influence from the field of view; uneven brightness of the sky; visible gaps in the canopy; decreasing pairs The need to measure the size of the plot; reduced the size of the necessary open space within the forest.
3. Pay attention to the influence of the slope In the process of measurement, some objects are on the slope, so it is necessary to pay attention to this. For the slope measurement, when using the crop canopy analyzer, the sensor should be kept as much as possible with the slope. Match, not the actual level.
4. Pay attention to the effect of plot size. As the sensor's field of view is 3 times the height of the canopy during the measurement process, this has requirements on plot size. If the size is too small, it will affect the measurement result. However, if it is really impossible to solve the problem that the sample size is too small, you can use the observation cap method or the data in the fifth ring to solve this problem.
Tire seal repairs small injuries in tubeless tires quickly and easily. It flows into the injury and completely seals the inner liner as well as broken cord and cable ends. Seal insert permanently vulcanizes through the tire injury, and the tire is immediately ready for use.
