Now drip irrigation technology has been widely used in the north and south of my country, and drip irrigation belt is a water-saving irrigation equipment commonly used in arid areas. This irrigation method is mainly through the installation of pipes with small holes above the plants, and the water continuously leaks and drips on the roots of the plants through the small holes. The use of drip irrigation belts generally has a control system to control the entire process, so what are the control methods of the system?
1. Fully automatic control.
The system does not require direct participation of human beings, and can automatically open and close the water pump for a long time and automatically irrigate according to a certain rotation sequence through the pre-programmed control program and certain parameters reflecting the water demand of crops. The role of people is only to adjust the control program and overhaul the control equipment. In this system, in addition to irrigators, pipes, fittings, water pumps, and motors, it also includes controllers, automatic valves, sensors, and wires.
2. Semi-automatic control.
There are no sensors installed in the irrigation area in the drip irrigation belt system. The irrigation time, irrigation amount and irrigation cycle are all controlled according to the pre-programmed program, rather than the feedback information of crop and soil moisture and meteorological data. The degree of automation of such systems varies, and some parts are automatically controlled, and some parts are automatically controlled.
3. Manual control.
All operations of the system are done manually, such as the opening and closing of pumps and valves, the length of irrigation time, when to irrigate, etc. The advantage of this type of system is that the cost is low, the technical content of the control part is not high, it is easy to use and maintain, and it is very suitable for promotion in the vast rural areas of our country.
The above are the three control methods of drip irrigation belt. The above three control methods have different operation methods and advantages in actual use, so we can choose according to our actual needs when choosing.
