Because of the shortage of water resources, it is common knowledge for everyone to promote water conservation and cherish every drop of water. According to statistics in 1998, China's annual water shortage due to drought will produce about 100 billion kg of grain, and unreasonable agricultural irrigation will waste a lot of water resources. Therefore, water saving irrigation technology has also been developed, and a soil moisture detector has also been developed. To make up for water shortages, how much to fill, and not to waste water resources. The main source of soil moisture is rainfall and irrigation. In a large part of the region north of the Yangtze River in China, it is arid and semi-arid region. The rainfall is seriously insufficient. The output of crops in these regions is severely limited and can only rely on irrigation. Water resources are also severely restricted in these areas. To ensure a certain amount of soil moisture and not to waste water resources, a soil moisture detector is used to monitor the soil moisture changes in real time, and the results of the measurements can be uploaded after testing. To the computer, the use of professional data analysis, such as seeing its analysis, allows us to understand the climax and trough of soil moisture, but also can clearly see the trend of soil moisture changes. 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. Architectural Tension Bar For Construction High Strength Steel Tie Rod are steel structural members made of carbon structural steel and alloy steel, processed by machining, heat treatment and surface anti-corrosion treatment, supplemented by adjusting sleeves, lock and joints etc. The steel tie rod are important components of steel structures for construction of giant, large span buildings and ship docks. They are mainly used for prestressed parts and large span buildings in construction projects. While the strength of the product is improved, but the plasticity index is not reduced, which satisfies the principle of using the same amount of strength in the architectural design. The tie rods, tie bars, tension rods and tension bars steel grades are specified as grade 460, grade 520, grade 550, grade 650.
