Eight Wrong Concepts In The Application Of Drip Irrigation Systems.
Mistake 1: Unreasonable irrigation system. The drip irrigation flow rate is low, the user often does not see the irrigation process. If the irrigation time is too long, deep leakage will be generated; if the irrigation time is too short, the root system will be hydrolyzed again. Understanding the irrigation intensity of the irrigation system, the water requirement of the plant, and the amount of water held in the field can better irrigate according to the needs of the plant. At the same time, it should be borne in mind that the irrigation cycle and the amount of irrigation should be adjusted according to the different growth stages of the climate and plants, and the same irrigation system cannot always be used.
Mistake 2: The wrong dripper is used. The dripper is usually divided into two models, pressure compensated and non-pressure compensated. Although the pressure compensation type is more expensive, the effect is better. First, the pressure-compensated dripper ensures that each dripper has a uniform effluent and uniform fertilization. Secondly, part of the pressure-compensated dripper can wash out the debris that blocks the dripper, and some pressure-compensated dripper flow paths are large, reducing the possibility of clogging of the dripper.
Mistake 3: The filter device is missing. Many users mistakenly believe that well water does not need to be filtered, and in fact well water often contains coarse sand, fine sand and some chemicals that block the dripper. Common filters include strainers, laminations, and media filters. If sand is present 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, the appropriate filtration facilities should be used according to the water quality, and the dripper with anti-blocking properties should be selected.
Mistake 4: No fertilization was done through the drip irrigation system. Simultaneous application of water and fertilizer is the advantage of drip irrigation. Plant root growth has the effect of water, fertility and fertilizer application with irrigation water**. However, the use of fertilization irrigation systems should have a fertilizer backflow prevention device to prevent fertilizer from contaminating groundwater and other water sources.
Mistake 5: Lack of routine maintenance. The drip irrigation system needs to be carefully maintained to perform its performance. Conditional units should always rinse the drip irrigation tube to ensure the smooth flow of equipment. According to actual needs, it can be considered to use an effective chemical treatment periodically.
Mistake 6: There are no pressure gauges and flow meters. These simple devices can help the user “spray” the irrigation system to solve the drip irrigation system problem that cannot be accurately judged by the naked eye. The pressure gauge is used to detect the pressure of the tip, middle and drip irrigation tube tails of the drip irrigation tube, and the history of the design pressure or water pressure can be used to judge the problem of the drip irrigation system. The flow meter helps the user to quickly determine the flow of the water source. In addition, the flow data helps to calculate the actual flow and historical flow of the irrigation system.
Mistake 7: I mistakenly believe that all drip irrigation tubes are of the same quality. Different drip irrigation pipes have different raw material qualities, production processes and patented technologies. More importantly, the dripper structure design of different brands of pipes is different. Drip irrigation pipes that provide uniform water and fertilizer, have anti-blocking properties, long life, and are easy to install and maintain.
Mistake 8: Ignore long-term operating expenses. Drip irrigation systems often use ten or more years to irrigate millions of cubic meters of water and fertilizer, so it is important to consider the uniformity of irrigation, the operating costs of the pumping station, and the cost of routine maintenance. A well-designed system that reduces post-run costs through its good uniformity or energy efficiency. In addition, some suppliers have a lot of experience and know-how to guide users in choosing the right irrigation system and to help with the operation and maintenance of the system.
