[0002] With the rapid development of modern agricultural technology, hydroponics, as an efficient and environmentally friendly planting method, has gradually occupied an important position in agricultural production. Hydroponics is a new type of soilless cultivation method for indoor plants, also known as nutrient solution cultivation. Its core is to fix the plant roots in a planting basket and allow the roots to naturally grow into the plant nutrient solution. This nutrient solution can replace natural soil to provide the plant body with growth factors such as water, nutrients, and temperature, enabling the plant to grow normally and complete its entire life cycle. Hydroponic plants cultivated using this soilless cultivation technology are favored by domestic and foreign flower consumers for their advantages such as cleanliness, elegance, strong ornamental value, and environmental protection and pollution-free. Hydroponic plants also need to be fertilized during the growth process, that is, adding nutrient solution. Therefore, it is necessary to design a fertilizing device for hydroponic plants.
