[0002] Water sampling is to collect water samples from polluted water bodies and obtain basic data on water pollution through analysis and measurement. With the rapid development of industry, water pollution in rivers, lakes and lakes is becoming increasingly serious, which has a serious impact on the quality of people's daily drinking water. Therefore, water sampling has become an important task for environmental workers. Water samples in farmland ecosystems generally include rainwater, irrigation water, runoff water and soil seepage water, etc., which should be sampled and preserved according to the requirements of the research. Rainwater can be collected from the rain gauge of the meteorological station, or placed in the open air with a container to receive water samples when it rains; irrigation water should be collected in irrigation ditches, or sampled at water sources such as reservoirs, ponds, rivers, and wells; runoff water can be taken from the outlet of the runoff measurement facility; soil seepage water can be collected by burying underground drainage pipes or establishing drainage collectors. In the process of using extension rods to collect water samples, it is often necessary to support the extension rods with both arms, which not only imposes a large burden on manpower, but also increases safety hazards to a certain extent.
