The difference between soil temperature and humidity recorders and fixed-point public opinion monitoring systems

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:
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.
