The intelligent automatic water and fertilizer integration system of greenhouse usually includes water source project (clean water tank and medicine tank), head hub, filtration system, field water transmission and distribution network system, electromagnetic valve wireless control analog signal return and PLC control software platform. Mainly with the help of drip irrigation system, the water in the drip irrigation system is used as the carrier to fertilize while irrigation, so as to realize the integrated utilization and management of water and fertilizer, so as to supply water and fertilizer to crops for absorption and utilization in an optimized combination state in the soil.

Intelligent water and fertilizer integration does not require manual operation. The system can realize the functions of automatic start and stop, remote operation, video monitoring, data monitoring, storage and upload.

The integration of water and fertilizer mainly has the following characteristics:

1. Modular design is adopted, which has strong compatibility and is easy to expand connecting equipment and add functions;

2. Adjust measures to local conditions, save water resources to the greatest extent and improve the utilization rate of water resources.

3. Intensive, unattended and automatic operation to save costs and reduce manpower.

Advantages of intelligent automatic water and fertilizer integration in Greenhouse:

1. Reduce the occurrence of diseases and pests: the integrated technology of water and fertilizer improves the soil permeability, reduces the air humidity in the greenhouse, increases the stress resistance of crops, inhibits the occurrence of crop diseases to a great extent, reduces the input of pesticides and labor input for disease prevention and control, and reduces the amount of pesticides per mu of micro irrigation and fertilization by 15% - 30%;

2. Time saving and labor saving: the water fertilizer integrated drip irrigation technology applies pipeline for irrigation and fertilization. It only needs to open the valve and dissolve the fertilizer into the fertilizer adding system without going to the ground. It can save a lot of labor, reduce labor cost investment and efficient management;

3. More conducive to environmental protection: after installing the intelligent Internet of things greenhouse, it can effectively save irrigation water and chemical fertilizer, which is also of great significance for environmental protection and more conducive to the sustainable development of the environment.
