In agricultural production, water and fertilizer integration technology for improving the utilization of water and fertilizer has a very significant role. The application of agricultural internet of things technology in the integration of water and fertilizer can help producers realize the integrated water and fertilizer management conveniently.
I. Overview
Integrated water and fertilizer technology is a new agricultural technology that integrates irrigation and fertilization. Water and fertilizer integration is the use of pressure systems (or natural terrain), the soluble solid or liquid fertilizer, according to soil nutrient content and crop needs of the law and characteristics of fertilizer, with the compost fertilizer and irrigation water, through the controllable pipeline The system supplies water, feeds the fertilizer, makes the water and fertilizer mix, forms the drip irrigation through the pipeline and the dripper, and evenly, regularly, quantitatively infiltrates the root growth area of ​​the crop so that the main root soil always remains loose and suitable water content, Vegetable fertilization characteristics, soil environment and nutrient status; water demand in different growth stages of vegetables, the need to regulate the pattern of fertility at different growth stages of the design, the water, nutrients regularly quantitative, in direct proportion to the crop.
Second, the scope of application: Water and fertilizer integrated intelligent irrigation system can be widely used in agriculture, soil fertility, plant protection, by, garden and other agricultural technology promotion or agricultural science and technology demonstration area, farms and other large agricultural production and processing enterprises.
Third, the system functions:
1, real-time monitoring of operating conditions:
Through the water level and video monitoring, it can monitor the water condition of drip irrigation system in real time and timely release the warning of water shortage. Through the monitoring of pump current and voltage, the outlet pressure and flow monitoring, the flow and pressure monitoring of pipe network, , Leakage, low pressure operation and other irrational irrigation events, promptly notify the system maintenance staff to ensure efficient drip irrigation system operation.
2, the valve automatic control function:
Through real-time monitoring of farmland soil moisture information, microclimate information and crop growth information. According to the collected information, combined with the demand of local crops and irrigated irrigation system, the pump is automatically turned on to realize unattended automatic irrigation, slice control and prevention of human error.
3, operation and maintenance management functions:
Water-saving irrigation automation control system can give full play to the existing water-saving equipment, optimize scheduling and improve efficiency, through the application of automatic control technology, more water and energy saving, reduce irrigation costs, improve irrigation quality, irrigation will make more scientific and convenient , Improve management level.
4, mobile terminal APP:
Facilitate management through mobile phones and other mobile terminal devices View system information anytime, anywhere, remote operation of related equipment.
Integrated management of water and fertilizer can not be separated from agricultural Internet technology
Water and fertilizer integrated intelligent irrigation system can help producers easily achieve automatic integrated management of water and fertilizer. Through the organic combination with the water supply system, to achieve intelligent control. The entire system can coordinate the work of implementing irrigation, fully improve the efficiency of irrigation water, to achieve irrigation, fertilizer timing, quantitative control, saving water and fertilizer, reducing labor intensity and reduce labor input costs. Effort to save time and increase production. The integration of water and fertilizer will surely become an important part in the development of intelligent and modern agriculture and will lead China's agriculture to a broader area.
