In modern horticultural and agricultural maintenance, the key to improving plant growth quality lies in the synchronous and efficient implementation of irrigation and fertilization. From home lawns to large-scale farmlands, sprinkler system fertilizer (sprinkler irrigation and fertilization systems) and various derivative equipment are gradually replacing traditional manual fertilization methods. With the advantages of precision and labor saving, they have become a new choice for maintenance.

Fertigation systems (irrigation and fertilization systems) form the core technical framework. They integrate liquid fertilizers with irrigation water and deliver the mixture directly to plant roots or leaves through pipelines. This model breaks the separation between "watering" and "fertilizing", avoiding fertilizer waste and soil compaction. Among them, irrigation fertilizer system (integrated irrigation and fertilization systems) can be further divided into multiple types. For example, the fertilizer system for sprinklers (specialized fertilization system for sprinkler irrigation) is designed specifically for sprinkler irrigation. It is compatible with sprinkler heads of different specifications, ensuring uniform fertilizer coverage over lawns or crop areas.

The fertilizer sprinkler (fertilizing sprinkler) is a common device for home use. It integrates a fertilizer storage tank with a sprinkler device; users only need to set parameters to achieve "fertilization while watering". For large-area maintenance, the liquid fertilizer injector system for lawn sprinkler (liquid fertilizer injection system for lawn sprinkler irrigation) is more advantageous. It uses the principle of negative pressure to inject liquid fertilizer into irrigation pipelines in proportion, and is compatible with municipal sprinkler networks, easily covering areas such as football fields and park green spaces.

In the professional agricultural field, irrigation system fertilizer injection (fertilizer injection technology for irrigation systems) is widely applied, leading to the development of equipment such as fertilizer irrigation injection (fertilization irrigation injection) and fertiliser injectors irrigation (irrigation fertilizer injectors). Such systems support precise control of fertilizer concentration and injection volume. When combined with sensors, they can dynamically adjust based on soil moisture and crop growth stages, reducing chemical fertilizer loss while increasing crop yield. For instance, the irrigation fertilizer injector (irrigation fertilizer injector) can be directly connected in series with the main pipeline of drip irrigation or sprinkler irrigation, requiring no modification to the original irrigation system, and featuring easy installation and low maintenance costs.

Whether for home gardening or large-scale agriculture, selecting suitable irrigation and fertilization equipment can achieve the maintenance goals of "water saving, fertilizer saving, and high efficiency". In the future, with the integration of intelligent control technology, such systems will be further upgraded to provide more scientific solutions for green space maintenance.
