[0002] The development of agriculture has a long history in my country. For thousands of years, the Chinese people have worked hard to cultivate this hot land. In modern times, with the rapid development of industry, more and more pollution has come along. Many lands are polluted by acids, alkalis, heavy metals, etc., and repairing these polluted lands has become an important issue. At present, soil remediation mainly relies on spraying agents or deep injection of drugs. However, in the process of these soil remediation, sampling and testing are required frequently to monitor the soil remediation status. General sampling work relies on manpower, and workers need to drill deep soil frequently, which consumes a lot of manpower. At present, there are some detection methods that bury the sensor probe underground, but the sampling data of such detection methods are not accurate enough, which often causes the staff to misjudge. When the soil remediation effect does not meet expectations, a complete injection remediation operation is required, which is time-consuming and laborious. Summary of the invention
