Technical Field

The utility model relates to an open-air soil PH concentration measurement device especially relates to a portable soil PH value survey device.

Background

With the rapid development of economy and rapid promotion of industry in China, cultivated land soil in China has a serious challenge. According to data in a geochemical survey report for cultivated land of China issued by the geological survey bureau of the ministry of China, the survey area is 150.7 kilo square kilometers, the survey area is nearly 14 hundred million acres, and accounts for 68 percent of 20 hundred million acres of cultivated land. The results of the investigation showed that 8% of the cultivated land was contaminated. Therefore, the investigation on the soil pollution is urgently needed. However, in the soil pollution investigation process, the pH value is one of the main physical and chemical indexes of soil, and is directly related to the growth vigor of plants. It is closely related to the formation process of soil and the effectiveness of various nutrients in soil, and plays a dominant role in oxidation reduction, precipitation dissolution, adsorption, desorption and coordination reactions in soil. In work, the difference between the soil pH value measured in a laboratory and the actual value in the field is often found to be large, and the difference can possibly cause a misarea of soil pollution investigation. Therefore, it is necessary to directly measure the PH concentration of the soil on site during the soil pollution investigation process, so as to ensure the accuracy of the PH value of the soil.
