1. Unreasonable irrational irrigation system
Low drip irrigation flow rate makes users often fail to see the irrigation process. If the irrigation time is too long, deep leakage and waste will occur; if the irrigation time is too short, water stress will occur in the root system.
Knowing the irrigation intensity of the irrigation system, plant water demand, and soil field water holding capacity can better irrigate according to plant needs. At the same time, keep in mind that the irrigation cycle and the amount of irrigation should be adjusted according to the climate and the different growth stages of the plants, and the same irrigation system cannot always be used.
2. Use the wrong drip irrigation dripper
The drip irrigation dripper is usually divided into two types, pressure-compensated and non-pressure-compensated. Although the pressure compensation type is more expensive, the effect is better.
First of all, the pressure compensation dripper can ensure that each dripper has even water output and uniform fertilization and irrigation. Secondly, some pressure-compensated drippers can wash out the debris that blocks the dripper, and some pressure-compensated drippers have a large flow channel, which reduces the possibility of dripper clogging.
3. Lack of drip irrigation filter
Many users mistakenly believe that well water does not need to be filtered. In fact, well water often contains coarse sand, fine sand and some chemicals, which block the dripper.
4. No fertilization through drip irrigation system
Simultaneous application of water and fertilizer is the biggest advantage of drip irrigation. The growth of plant roots is water-oriented and fertile-oriented, and the application of fertilizer with irrigation water has the highest efficiency.
5. The drip irrigation system lacks daily maintenance
Drip irrigation systems need to be carefully maintained for optimal performance. Qualified units should flush the drip irrigation pipe frequently to ensure the unblocked water flow of the equipment. According to actual needs, you can consider using effective chemical treatment periodically.
6. The drip irrigation system has no pressure gauge and flow meter
These simple devices can help the user to "keep the pulse" of the drip irrigation system to solve the drip irrigation system problems that cannot be accurately judged by the naked eye.
Use a pressure gauge to detect the pressure at the head, middle, and tail of the drip irrigation tube, and compare the design pressure or the history of water pressure to determine the problem of the drip irrigation system. The flow meter can help users quickly judge the flow of the water source. In addition, the flow data helps to calculate the actual flow and the historical flow of the irrigation system.
7. Pipeline selection of drip irrigation system
Different drip irrigation pipes have different raw material quality, production technology and patented technology. More importantly, the dripper structure design of different brands of pipes is different. You should choose a drip irrigation pipe that can provide uniform water and fertilizer, has anti-blocking properties, has a long life, and is easy to install and maintain.
8. Ignore the long-term operating cost of drip irrigation system
Drip irrigation systems often take more than ten years or more than 20 years to irrigate millions of cubic meters of water and fertilizer. Therefore, it is very important to consider the uniformity of irrigation, the operating costs of the pumping station, and the daily maintenance costs.
A well-designed system in the early stage can reduce the operating cost in the later stage through its good uniformity or energy saving. In addition, some suppliers have a lot of experience and know-how, can guide users to choose the correct drip irrigation system, and provide assistance in operating and maintaining the system.
