In the scientific research of soil, plant nutrition and ecological environment, soil solution is one of the important research contents. The soil solution is compared to the "blood circulation in the soil". It is not only the site of most soil chemical reactions and soil formation processes, but also the source of nutrients for the root system of plants. Therefore, in modern agricultural research, soil solution sampling devices are used to sample soil solutions, and laboratory research is becoming more and more frequent. The soil solution sampler is a professional instrument for sampling soil solution. It is also called a soil solution extractor, a soil solution sampler, a suction osmometer, etc., and is mainly used for collecting soil solution samples in a soil profile. What is the complete working process of the soil solution sampler? The basic composition of the soil solution sampler is a porous ceramic head and a sample collection tube. During the sampling process, we only need to place the soil solution sampler at the appropriate depth of the soil and perform periodic sampling with minimal agitation of the soil. Measurement, this time the vacuum pump will produce a vacuum in the sampler, from the soil through the ceramic head sucking soil solution into the sampler, then the extracted solution will be extracted from the collection tube, in the laboratory for chemical analysis, this is the soil The complete working process of the solution sampler. The use of a soil solution sampler to carry out sampling of soil solutions is a relatively simple, highly operational, and very useful sampling method. Its application has effectively increased the progress and efficiency of modern research on soil solution research. It is also Research workers have reduced the workload. With the development of science and technology, Topsun developed and produced a more advanced suction-type soil solution sampler, which can be used to extract different layers of soil in situ in the field, which further simplifies the soil solution sampling process and optimizes Because of the sampling effect, it has been widely used in agricultural production, scientific research and other fields, and has played an important role in the research of environmental pollution monitoring and groundwater utilization.
