The composition of the soil is complex, so the water in the soil is not pure water, but contains various soluble substances called soil solutions. The soil solution reflects the history and characteristics of the soil type to a certain extent, and also reflects the seasonal dynamics and agricultural conditions. On the one hand, the soil solution can be used as a plant nutrient source, and on the other hand, it is contaminated by some metal ions, so the soil solution changes. It is related to agricultural production and environmental protection. In recent years, research on soil solutions has become more and more extensive in these related fields. To carry out soil solution research, the first is to extract soil solutions. Here is a new soil solution extraction technology- soil solution sampler , which can efficiently and accurately collect soil solutions, which facilitates the development of various researches. The soil solution extraction technology has been divided into several stages, which can be mainly divided into destructive sampling and non-destructive sampling. Destructive collection requires the soil sample to be taken out from the ground, and sometimes it needs to be air-dried and rewet, instead of destructive sampling. There is no need to collect soil samples, and continuous sampling can be performed with minimal soil disturbance. The soil solution sampler uses non-destructive sampling, so sampling with the instrument is not only easier and simpler, but also more accurate, which is more conducive to the soil solution sampling work in the field. The traditional sampling of soil solutions is mostly carried out by collecting samples in the field and using the soaking solution method. This method not only has a large workload, but also cannot determine the dynamic changes of the solute. In fact, the soil solution in the soil will change continuously due to soil texture, water content, and microbial activity, and the absorption and utilization of plants. Therefore, in order to carry out soil solution research, it is best to periodically locate the soil solution and monitor the law of the soil solution. The soil solution sampler provides such a reliable soil solution extraction technology, so the instrument has been widely promoted and applied in the fields of soil and fertilizer research, soil pollution, water conservancy departments and environmental monitoring.
