Background
In the existing garden management technology, fertilization and irrigation of greening trees in gardens are a crucial task. However, the conventional manual control of the spray truck has a series of significant drawbacks and challenges, which limit its efficiency and practicality, and seriously affect the maintenance and beautification of gardens.
Inefficiency and manpower resource intensive: the manual mode of operation typically requires a significant amount of human resources because the worker must hold the spray gun or equipment to apply fertilizer and spray, either plant by plant or on a per-plant basis. This is not only time consuming and laborious, but also inefficient, especially in large-area gardens.
Difficult plant type adaptation: different plant types and varieties typically require different types and proportions of fertilization and irrigation. The manual mode is difficult to adjust to the needs of a particular plant because operators may lack accurate information and tools to ensure accurate fertilization and irrigation.
Cannot cover difficult-to-access areas: in gardens, there are areas that are difficult to access, such as narrow small diameters, overhead crowns, or obstacles, which are not covered by conventional spray vehicles, resulting in insufficient attention to some plants.
Not fine and accurate enough: manual control has artificial factors, and uniformity and accuracy of fertilization and irrigation are difficult to ensure. This can lead to excessive or insufficient nutrient input, affecting plant growth and health.
The above information disclosed in the above background section is only for enhancement of understanding of the background art for the technology described herein and therefore it may contain some information that does not form the prior art that is already known in the country to a person of ordinary skill in the art.
