[0002] With the development of agriculture, the production and application scope of liquid fertilizers are expanding. Liquid fertilizer is a new type of high-efficiency compound fertilizer. Compared with solid fertilizers, liquid fertilizers have the advantages of fast fertilizer effect, no caking, diverse usage methods, and less pollution during production, transportation and use.

[0003] In order to ensure its quality and safety, liquid fertilizers are often sampled and tested to determine whether their composition, concentration, nutrient content and other parameters meet standard requirements, and whether there are harmful substances or pollutants. This can avoid the negative impact of low-quality fertilizers on crops and ensure the normal growth and healthy development of crops. At present, when sampling liquid fertilizers, most of them are directly extracted from liquid barrels. Since the concentration and quality of liquid fertilizers at each height are different, it is not convenient to sample and test liquid fertilizers at different levels, which affects the detection effect.
