Land remediation sample assay detection device and detection method

The invention belongs to the technical field of land sample detection equipment, and particularly relates to a sample assay detection device for land remediation and a detection method.The sample assay detection device comprises a bottom plate, the lower surface of the bottom plate is fixedly connected with a sampling insertion pipe, the upper surface of the bottom plate is fixedly connected with a threaded cover, and the inner wall of the threaded cover is in threaded connection with a threaded ring; an insulating transparent measuring cylinder is fixedly connected to the inner wall of the threaded ring, and an electric push rod is fixedly embedded in the top end of the insulating transparent measuring cylinder. The anti-interference capability of the soil sample assay detection device to the environment can be effectively improved, and the sample assay detection device also has a soil acidity and alkalinity detection function, so that the soil salinity structure detection accuracy of the device is improved,
