Water and fertilizer machine
Water and fertilizer integration technology is favored by more and more farmers because of its high efficiency and characteristics of saving water and fertilizer. However, in the use of water and fertilizer machine, there are still some common misunderstandings that affect its effect. In order to obtain better results, the following aspects should be paid attention to:
✅1. Ignore the filter device
Filter selection and maintenance is very important. Common filter types include centrifugal, screen, laminated and sand filters. At the end of the irrigation season, the filter element should be thoroughly cleaned and maintained to ensure that the irrigation system is not blocked by impurities.
✅2. Improper fertilizer selection
The irrigation channel of the integrated water and fertilizer system is small, and it is easy to be blocked by impurities in the insoluble fertilizer. It is recommended to use fully water-soluble fertilizers to ensure their smooth circulation in the system and improve the efficiency of use.
✅3. Unreasonable irrigation system
The proper irrigation system needs to be flexible to adapt to climate change, plant growth stage and soil conditions. Long irrigation times can cause water and fertilizer to leak to deep layers, wasting resources and affecting crop absorption.water and fertilizer system.
✅4. Lack of application of monitoring tools
In order to effectively monitor the operating status of the system, it is necessary to install pressure gauges and flowmeters. Only by ensuring that the pressure and flow of the drip irrigation system operate within the design range can the stable operation of the system be guaranteed.water and fertilizer system.
✅5. Neglect the maintenance of electrical components and sensors
Regular maintenance of control electrical components (such as air switches, contactors, etc.) and sensors to ensure that system pressure, conductivity, pH value monitoring is accurate in case of data anomalies.
✅6. Ignore network and communication maintenance
With the popularity of the application of the Internet of Things technology, the status of the network and servers are regularly checked to ensure that the remote operation is accurate and timely, which can ensure the timely response and precise control of the system during the operation of the equipment.water and fertilizer system
✅7. Lack of anti-backflow device
In the process of fertilization in the integrated water and fertilizer system, it is necessary to install an anti-backflow device to prevent fertilizer from backflowing into groundwater and causing pollution.
✅8. Choose the wrong dropper water and fertilizer system
The dripper is divided into pressure compensation type and non-pressure compensation type, which should be selected according to the terrain characteristics of the park. The non-pressure compensation type is generally suitable for short distance laying in plain areas, and the pressure compensation type is suitable for areas with large drop difference such as mountains and hills to ensure the uniformity of effluent and water and fertilizer system fertilization.
✅9. Lack of routine maintenance
After the irrigation season every year, it is necessary to conduct a comprehensive inspection and maintenance of the pipes and equipment, wash the pipes regularly, water and fertilizer system,and maintain the system performance to extend the service life.
✅10. Ignoring long-term operating costs
The uniformity and energy efficiency of the system should be considered at the beginning of the design, and the selection of experienced suppliers and high-quality equipment to reduce long-term operating costs is essential for long-term stable and economical system operation.
