Fertilizer System in The Greenhouse Application

In greenhouses, integrated irrigation systems are used. Intelligent water-fertilizer integration technology effectively designs the nutrient elements needed for vegetable growth, mixes water and fertilizer in appropriate proportions, and uses drip irrigation tape to evenly deliver the fertilizer to the roots at a low flow rate. Therefore, applying intelligent water-fertilizer integration technology in greenhouses can effectively address the problems of severe water waste and inaccurate fertilizer-liquid ratios, thereby achieving the goal of improving vegetable quality and increasing yields.
In a narrow sense, integrated water and fertilizer technology involves mixing soluble fertilizer with water and irrigating the crops. Generally speaking, this involves mixing water and fertilizer and supplying them to the crops they need to ensure their growth. Intelligent integrated water and fertilizer technology combines traditional integrated water and fertilizer technology with modern agricultural technology. Using new equipment, soluble granular or liquid fertilizers are blended into a corresponding nutrient solution based on crop growth needs and soil nutrient content. This solution can then be delivered to crops in a quantitative, timely, scientific, and accurate manner.

Intelligent integrated water and fertilizer technology primarily relies on irrigation equipment and fertilization devices. Control devices mix water and fertilizer according to a formula and ultimately deliver the mixture to the crops. The system components of intelligent integrated water and fertilizer technology primarily include a water source, a pressure pump, a laminated filter, a sand and gravel filter, a flow meter, a pressure gauge, an intelligent control platform for the water and fertilizer machine, a fertilizer mixing tank, and field drip irrigation pipes. Common crop sensors are installed in the greenhouse to collect information such as temperature, humidity, and CO2 concentration, enabling effective integration with the water and fertilizer machine.
The fertigation machine's control system incorporates a Venturi tube fertilizer applicator, EC and pH meters, and a pressure pump enhances mixing when fertilizer mixing is insufficient. Four mixing tanks can be used to add fertilizers containing various trace elements, effectively controlling crop irrigation and fertilization.
Compared to traditional flood irrigation, intelligent fertigation technology utilizes drip irrigation to evenly distribute fertilizer to crops. Experimental data indicates that fertilization with fertigation improves water utilization by 40% to 60%. Furthermore, compared to traditional flood irrigation, it saves time, effort, and labor costs, making it highly beneficial for large-scale cultivation.
Fertilization uses a water and fertilizer machine that automatically mixes fertilizers according to plant needs, and drip irrigation tape is used for irrigation. This process reduces the loss of fertilizers and chemicals through volatilization, as well as soil compaction caused by excess nutrients. Furthermore, the water and fertilizer machine can be controlled to accurately match water and fertilizers based on the experience of local soil experts or growers. This makes fertilization very simple, saves labor, and ensures accurate fertilizer application, reducing human waste. Compared to traditional technologies, it increases utilization by 40% to 50%.

Most agricultural products and vegetables are susceptible to pests and diseases, which are often caused by excessive humidity and insufficient sunlight in greenhouses. Using integrated water and fertilizer technology can effectively control humidity within greenhouses, reducing losses caused by pests and diseases to growers. Furthermore, this can significantly improve the quality of agricultural products, increase income, and reduce pesticide usage and manual application costs.
The intelligent integrated water and fertilizer machine can adjust and add irrigation plans according to the user's needs, set time cycle plans, and realize intelligent control. Various pressure and flow sensors are also installed in the entire water and fertilizer machine equipment to effectively monitor the irrigation operation status and realize an automated irrigation and fertilization, saving a lot of human resources.
Combined with various sensors installed in the greenhouse, the integrated water and fertilizer machine can mix fertilizers in a targeted and proportional manner. The trace elements required by the crops are placed in the fertilizer mixing bucket, and the water and fertilizer machine will automatically mix the fertilizers as needed and deliver them to the root growth area of the crops in a timely, quantitative and even manner through the drip irrigation pipes. This keeps the soil loose and prevents it from becoming compacted, improving the growth of the crops.
The growth of most vegetables will be affected by the moisture and nutrients in the soil. The intelligent water-fertilizer integrated technology can match a suitable fertilizer solution and reasonable irrigation according to factors such as humidity feedback from sensors in the greenhouse, so that the soil environment maintains the optimal environment required by vegetables, thereby maintaining vigorous growth throughout the entire crop growth cycle.

Vegetable greenhouses use intelligent water-fertilizer integration technology to effectively promote vegetable production to increase quantity, enhance and improve economic benefits, and achieve long-term development of the entire vegetable industry.
