Abstract
Description
Technical Field
[0001] This utility model relates to the field of plant cultivation technology, and in particular to an intelligent water and fertilizer equipment and system. Background Technology
[0002] In plant cultivation, the supply of water and nutrients is crucial for ensuring healthy plant growth. Traditionally, fertilization and irrigation are separated, which is not only labor-intensive and time-consuming but also makes it difficult to ensure even distribution of water and fertilizer, resulting in low fertilizer utilization and water waste. In recent years, with technological advancements, water-fertilizer mixing equipment has been increasingly applied to plant cultivation. This equipment involves placing fertilizer and water in the same container, manually stirring to dissolve the fertilizer, and then directly using the mixture for irrigation. While this method is an improvement over traditional methods, several problems remain in practice. For example, insufficient stirring can hinder fertilizer effectiveness, and the amount of water added often relies on experience, making precise control difficult and resulting in a mixture that is either too diluted or too concentrated, negatively impacting tree growth. Furthermore, manual stirring is both labor-intensive and inefficient. Therefore, a system capable of precisely dispensing, automatically mixing, and efficiently delivering water and fertilizer is essential. It not only saves labor but also improves water and fertilizer utilization efficiency, providing a more balanced nutrient supply to trees and promoting their healthy and stable growth. Therefore, it is evident that scientific and reasonable water and fertilizer equipment has become an indispensable tool in modern plant cultivation. Utility Model Content
