The degree of acidity and alkalinity of soil is mainly determined by pH value. Therefore, soil pH is also called soil pH. In modern agricultural soil testing, in order to scientifically detect the pH of soil, the method is very simple. It can be accurately used directly by soil pH meter. Determine and record the value. Soil is divided into acidic soil, neutral soil and alkaline soil according to different pH values. Among them, the soil with a pH value of 6.5-7.5 is called neutral soil, and the pH value is <4.5, which is a strong acid soil, the pH value is in the range of 4.5-5.5, which is acidic soil, and the pH value is in the range of 5.5-6.5. Inside, it is a weakly acidic soil with a pH between 7.5 and 8.5. It is a weakly alkaline soil with a pH between 8.5 and 9.5. It is an alkaline soil with a pH > 9.5, which is a strongly alkaline soil. From this we can see that through the pH value, we can clearly judge the degree of acidity and alkalinity of the soil and accurately evaluate the quality of the soil. Therefore, the determination of pH has become an important soil test in modern agriculture. The project, the soil pH meter, has also been widely used as a professional soil pH measuring instrument. At present, due to unscientific soil management, many orchards, vegetable planting bases, and greenhouse soils have different degrees of soil acidification problems, and soil acidification not only aggravates soil compaction, inhibits root development, but also causes soil quality. Falling and many other issues. The use of soil pH meter to accurately determine the pH value of the soil helps to use the data to visually assess the degree of soil acid and alkali, scientifically guide soil improvement and management in the production process, and provide a healthy soil foundation for the development of modern agriculture. Secondly, the application of soil pH meter can also help to improve the technical level of modern soil environment testing, promote the smooth development of farmland soil protection and upgrading work, and promote the upgrading and development of modern agriculture. The password lock anti-theft door is safer and more convenient than the ordinary anti-theft door. The door lock of the password lock anti-theft door is electronically controlled with a digital keyboard, and a number series is typed in sequence when it is opened. The advantage is that you only need to tell the unlocker the password without duplicating the key.
