Error 1: Unreasonable irrigation system. The drip irrigation flow rate is low, and users often cannot see the irrigation process. If the irrigation time is too long, deep seepage will cause waste; if the irrigation time is too short, the root system will suffer from water stress. Understanding the irrigation intensity of the irrigation system, plant water requirements, and soil field capacity can better irrigate according to plant needs. At the same time, remember that the irrigation cycle and irrigation amount should be adjusted according to the climate and different growth stages of the plant, and the same irrigation system should not be used all the time.
Error 2: Using the wrong dripper. Drippers are usually divided into two models: pressure-compensating and non-pressure-compensating. Pressure-compensating drippers are more expensive but more effective. First, pressure-compensating drippers ensure that each dripper delivers water evenly, and fertilization and irrigation are uniform. Second, some pressure-compensating drippers can flush out debris that clogs the drippers, and some pressure-compensating drippers have large flow channels, reducing the possibility of dripper clogging.
Error 3: Lack of filtration equipment. Many users mistakenly believe that well water does not need to be filtered, but in fact, well water often contains coarse sand, fine sand, and some chemicals, which clog the drippers. Common filters include filter screens, pleated filters, and media filters. If there is sand in the water, a centrifugal filter should be used. Before starting the installation of the filtration system, the physical and chemical composition of the water quality should be analyzed, and appropriate filtration facilities should be used according to the water quality, and drippers with anti-clogging performance should be selected.
Error 4: No fertilization through the drip irrigation system. Simultaneous water and fertilizer application is the biggest advantage of drip irrigation. Plant roots grow towards water and fertilizer, and the efficiency of fertilizer application with irrigation water is the highest. However, the fertilization and irrigation system should have a device to prevent fertilizer backflow to prevent fertilizer from polluting groundwater and other water sources.
Error 5: Lack of daily maintenance. The drip irrigation system needs careful maintenance to achieve optimal performance. Units with the conditions should regularly flush the drip irrigation pipes to ensure the smooth flow of water in the equipment. According to actual needs, the periodic use of effective chemical treatment can be considered.
Error 6: Lack of pressure gauges and flow meters. These simple devices can help users "take the pulse" of the irrigation system to solve problems that cannot be accurately judged with the naked eye. Using a pressure gauge to detect the pressure at the head, middle, and tail of the drip irrigation pipe, and comparing it with the design pressure or historical water pressure, can determine the problems of the drip irrigation system. The flow meter can help users quickly determine the flow rate of the water source. In addition, the flow data helps calculate the actual flow rate and the historical flow rate of the irrigation system.
Error 7: Mistakenly believing that all drip irrigation pipes are of the same quality. Different drip irrigation pipes have different raw material quality, production processes, and patented technologies. More importantly, the dripper structure design of pipes from different Brands is different. Drip irrigation pipes that can provide uniform water and fertilizer, have anti-blocking performance, long life, and are easy to install and maintain should be selected.
Error 8: Ignoring long-term operating costs. Drip irrigation systems often last for ten or twenty years, irrigating millions of cubic meters of water and fertilizer, so it is very important to consider the uniformity of irrigation, the operating costs of the pump station, and the daily maintenance costs. A well-designed system can reduce later operating costs through its good uniformity or energy saving. In addition, some suppliers have a lot of experience and proprietary technology that can guide users to choose the correct irrigation system and provide assistance in operating and maintaining the system.
