The shortage of water resources is a common problem in countries all over the world. At the same time, the lack of water resources is also a major factor that restricts the increase of grain production in countries around the world. Water limits China’s grain production, and in 1998, it was found that China’s food shortage due to drought is less than that of grain. About 100 billion kilograms of grain, in various countries, as long as proper treatment of soil moisture is performed in order to increase grain production, we can ensure the grain yield and quality to a certain extent. This problem can be measured by using a soil moisture detector during the operation and understand the soil moisture conditions to ensure the moisture requirement of the crop.
In a large part of the region north of the Yangtze River in China, there is a military term for arid and semi-arid regions where there is a relatively small amount of rainfall, and the production of crops in these regions is severely limited. In this case, it is necessary to To meet the basic requirements of “droughts and droughts, and encounter floodsâ€, when there is drought or water, how much water can be considered as drought? Specific changes in the soil moisture content cannot be viewed with the eyes. In this case, it is necessary to use a professional instrument for measuring soil moisture to perform operations. It is possible to use a time-sensitive soil moisture velocity meter or to use multifunctional soils. The moisture recorder is used to operate, and this instrument can be used to monitor the soil moisture changes in real time. After the inspection, the measurement results can be uploaded to the computer. Using professional data analysis, see its analysis, Let us understand the climax and trough of soil moisture, and at the same time let me clearly see the changing trend of soil moisture. However, when using soil moisture to monitor soil drought conditions, there is one thing that cannot be ignored. That is, the change of soil moisture must be combined with the nature of the soil to determine the state of soil drought. Moisture changes are measured.
In arid and semi-arid regions, the main source of soil moisture is rainfall and irrigation. Rainfall is severely deficient in these areas. Water resources are also severely restricted in these areas. In these areas, the use of time-based localization of soil moisture is used. Measuring the instrument to analyze and measure the soil moisture can reduce the amount of water used, and at the same time ensure the yield of the crop. Why not?
