Precipitation has a very important effect on the crop industry because moisture is the basic material for crop growth. The amount of precipitation directly affects people's quantity and time of crop irrigation. Only effective testing of precipitation can ensure the health and growth of crops, and can ensure the yield and quality of crops, thereby increasing economic benefits. In the precipitation measurement process, a rain recorder is generally selected for measurement. We have encountered daily deviations in the remote measurement rainfall and actual rainfall due to a variety of factors, so we must pay attention to the daily rainfall recorder maintenance, timely detection of problems and troubleshooting is necessary, only the normal instrument to ensure the rainfall data Authenticity and accuracy.
Routine maintenance work is very important: check the rainfall recorder at least once a month, remove dust, sand, and insects on the filter screen so as not to block the pipeline. Thoroughly inspect after strong winds and heavy rain, and pay special attention to keeping the funnel open. In the season of heavy sandstorm, no rain or little rain, the water retainer mouth can be capped, but pay attention to open it in time before precipitation. The inner wall of the dump is forbidden to be wiped with hands or other objects to prevent it from being stained with oil. When cleaning and maintenance, disconnect the signal cable. Pay attention to cleaning the spider web inside the rain tube during the summer so as not to affect the turnover of the dump. After each thunderstorm, it is necessary to check whether the lightning protection facilities are normal, and often remove the barrels for inspection. Attention should be paid to disassembly and assembly, and you must not hit the tipping bucket to cause it to turn over. In winter, the water trap of the sensor is capped. It should be noted that during the troubleshooting process, note that if you test the rain count and the reed switch, do not upload the data and remove it in time. Replacement of the instrument, and the first heavy rain that was reactivated in March, should be compared in terms of accuracy. That is to say, the amount of self-discharge is compared with the count and recorded value. If it is found that the difference exceeds ± 4%, it should first check whether the recorder is working properly, whether the count and the recorded value are consistent, and whether the reed switch is missing or multi-signaling. If it is due to the incorrect position of the base point of the instrument, the base point adjustment should be made.
The objectivity and accuracy of the numerical values ​​measured by the rainfall recorder make the instrument play its due role in the meteorological observation business. It is the responsibility of every business person and technician. Only by ensuring the accuracy of the instrument can we combine the results of the measurement with the growth of the crop, so that timely and appropriate measures can be taken to promote the growth of the crop and increase the utilization of water resources.
