The integrated water and fertilizer machine is a core intelligent device for precision irrigation and fertilization in modern agriculture. It integrates irrigation and fertilization, relying on pipeline water delivery to achieve synchronous water and fertilizer supply. It is widely used in scenarios such as greenhouse facilities, open-air fruit and vegetable bases, garden nursery stock, and large-scale field planting, completely changing the traditional extensive farming mode of flood irrigation and manual fertilization.
In greenhouse cultivation, this equipment is the most commonly used. Cucumbers, tomatoes, strawberries, peppers, and other economic fruits and vegetables require a large amount of fertilizer during their growth period, and their nutrient needs change with different stages. The integrated machine can precisely adjust the concentrations of nitrogen, phosphorus, potassium, and trace elements according to preset formulas, and deliver them directly to the soil around the crop roots through drip irrigation and micro-sprinkler systems. It can automatically switch the water-fertilizer ratio according to the crop's seedling stage, flowering stage, and fruit-expanding stage, and can control the amount of water per irrigation to avoid fertilizer loss and soil compaction caused by heavy watering. This effectively improves the fruit-setting rate and fruit quality of fruits and vegetables, reduces the problem of misshapen fruits, and saves more than 30% of fertilizer per acre.
The open-field and orchard planting are also compatible with the integrated water and fertilizer machine. Fruit trees such as apples, citrus, and grapes have deep and wide root distributions. The equipment can mix water and fertilizer through the main unit, deliver it to the roots of each fruit tree through branch pipes, and supply nutrients in a timely and quantitative manner. For large-scale fields such as wheat and corn, the combination with reel sprinkler irrigation equipment achieves large-area automated water and fertilizer spraying, which is especially suitable for water-scarce and arid areas. It greatly improves the utilization rate of water resources and alleviates the problem of water shortage for farmland irrigation.
Landscaping and nursery gardens are also important application areas. Flower seedling cultivation is highly sensitive to water and fertilizer. A slight increase in concentration can cause seedling burn and root rot. The all-in-one machine can precisely dilute the fertilizer solution and water the seedlings in small amounts but multiple times as needed, ensuring the healthy growth of the seedling roots. Urban green belts and nursery bases can be connected to intelligent control systems, which can automatically start and stop equipment based on soil moisture and nutrient sensor data, eliminating the need for frequent manual monitoring and maintenance, thereby reducing labor costs in garden maintenance.
In addition, the integrated water and fertilizer machine can be connected to the Internet of Things platform, allowing remote setting of irrigation duration and fertilizer ratio through a mobile phone terminal, as well as monitoring soil pH and water and fertilizer remaining levels, enabling unmanned field management. It excels in water and fertilizer conservation, quality improvement and yield increase, soil improvement, and reduction of agricultural non-point source pollution. It is an indispensable key equipment for the transformation and upgrading of green ecological agriculture and large-scale modern agriculture.
