When irrigating, many of the large-scale agricultural households basically conduct regular and quantitative irrigation of the farmland. Most of the irrigation methods are carried out using nozzles, but they do not consider whether this land is used for irrigation. Really need water, what is the amount of water needed, which is also very prone to irrigation is the excessive use of water, resulting in the waste of water and other issues, personal advice before using irrigation to use the instrument to understand the water shortage of the soil , You can use the soil temperature and humidity recorder, fixed-point public opinion monitoring system to measure, when using it should pay attention to the following aspects:
W-Shaped Steel Strap(W Steel Band) is a new type of mine support material. This product can be combined with various anchor rods to combine anchor plate brackets. Through it, multiple anchor rods can be connected to form an overall load-bearing structure, which significantly improves the overall effect of the bolt. In incomplete roof rock formations, it is more effective in dealing with unstable surrounding rocks.
Excellent material and quality assurance
The W Steel Strap is named after its cross section resembles the letter "W", and it is made of Q235. W Steel Strap is also called roof steel strap, which is a section steel product formed by continuous cold bending and rolling of multiple sets of rolling mills using slit steel as raw material.
Wide application and supporting effect
W strap steel is a new type of mine support and tunnel support material. Its function is to combine with bolts to form a bolt support grid, which plays a role in supporting rock walls or roadways. W steel strap is widely used in underground mine roadways, working face cuts, bunker rooms and other areas of roadway support, and it has a better effect on handling unstable surrounding rocks.

The soil temperature and humidity recorder is mainly used to measure the moisture and temperature in the soil. When judging drought conditions, it must be noted that soil moisture can not be judged only by using soil moisture, but soil properties can also be considered. Soil can generally be classified into sand, clay, and soil. Loamy soil, in which the moisture content of clay is the highest, followed by loam soil, the soil moisture content of sandy soil is the minimum. Only after considering the nature of soil can we accurately determine the soil drought condition.
The fixed-point public opinion monitoring system is a professional measurement instrument for measuring the state of public opinion. It can perform indoor or field monitoring of various soil soils, quickly and accurately detect the volumetric water content of the soil, and monitor soil moisture. . It can not only test the soil surface moisture, but also can bury deep underground and test different deep soil moisture at the same time. It can meet the research, production, teaching and other related work needs of the above industries. It has made corresponding contributions to water-saving irrigation, greenhouse control, and precision agriculture.
