[0002] In recent years, with the development of agricultural modernization, the prevention and control of crop diseases, pests and weeds has become an important part of agricultural production. In order to scientifically and rationally select, use and monitor pesticides (including herbicides), it is particularly important to accurately sample and test farmland soil, plants and other samples. Environmental pollution and ecological damage are increasingly attracting people's attention, and the impact of pesticide residues on the environment and human health has attracted much attention. Therefore, the demand for monitoring and testing of pesticide residues is increasing, and more accurate and reliable sampling devices are needed to support related work.
