Introduce

Integrated water and fertilizer management is an agricultural technology that organically combines irrigation and fertilization. It supplies water and fertilizer through a controllable pipeline system, and after the water and fertilizer are mixed, they are evenly and accurately delivered to the soil around the roots of crops. With the continuous development of information technology, sensor technology and other technologies, water and fertilizer integrated systems have become more intelligent and precise. They can automatically adjust water and fertilizer supply according to the real-time needs of crops, further improving the efficiency of water and fertilizer utilization and agricultural production benefits, and providing strong support for achieving sustainable agricultural development.

System composition

1. Water source: It can be well water, river water, lake water, etc. After filtration and other treatments, it provides clean water for the system.

2. Fertilizer supply system: including fertilizer tanks, fertilizer applicators, etc. The fertilizer tank is used to store the fertilizer solution, while the fertilizer applicator injects the fertilizer solution into the irrigation pipeline according to the set application amount, mixes it with the irrigation water and then transports it to the field.

3. Irrigation systems: Common ones include drip irrigation, sprinkler irrigation, etc. The drip irrigation system slowly drips the water-fertilizer mixture into the soil around the roots of crops through emitters installed on the drip tubes. It has the advantages of water conservation, energy saving and fertilizer saving, and is suitable for most crops. Sprinkler irrigation systems spray water and fertilizer mixtures onto crops through nozzles, forming fine water droplets that evenly fall on the surfaces of crops and soil. They are suitable for crops with high humidity requirements or large-scale planting.

4. Control system: Composed of sensors, controllers, etc. Sensors can monitor parameters such as soil moisture, nutrient content and temperature in real time. The controller automatically controls the time and amount of irrigation and fertilization based on the data collected by the sensors and the preset growth requirements of crops, achieving precise irrigation and fertilization.

Advantages

1. Enhance water and fertilizer utilization rate: It can accurately supply water and fertilizer to the roots of crops based on their water and fertilizer requirements, reducing water evaporation and fertilizer loss, and significantly improving water and fertilizer utilization rate. Generally, it can save 30% to 50% of water and 20% to 30% of fertilizer compared with traditional irrigation and fertilization methods.

2. Promoting crop growth: It provides a stable and suitable water and fertilizer environment for crops, enabling their root systems to fully absorb water and nutrients, thereby promoting crop growth and development, and increasing crop yield and quality. For instance, in vegetable cultivation, the application of integrated water and fertilizer technology can enable vegetables to be brought to market earlier, with plump fruits, bright colors and better taste.

3. Labor saving: It has achieved automated management of irrigation and fertilization, eliminating the need for frequent manual watering and fertilization operations. This significantly reduces labor intensity and saves labor costs. At the same time, it also reduces problems such as water and fertilizer waste and inconsistent crop growth caused by non-standard manual operation.

4. Improve soil environment: It avoids the damage to soil structure caused by flood irrigation and excessive fertilization, maintains soil air permeability and water permeability, is conducive to the activity of soil microorganisms, promotes the transformation and release of soil nutrients, and long-term use can improve the physical and chemical properties of the soil and enhance soil fertility.

5. Reducing the occurrence of pests and diseases: A reasonable supply of water and fertilizer enables crops to grow vigorously and enhances their resistance to pests and diseases. At the same time, by avoiding the situation of excessive humidity in the field caused by traditional irrigation methods, the environmental conditions for the breeding of pests and diseases are reduced, thereby lowering the occurrence rate of pests and diseases and reducing the use of pesticides.
