Drip irrigation is a common irrigation technique today. It is not only efficient in saving water, but also improves grain yield. Since the invention of drip irrigation, flood irrigation has been gradually abandoned. However, any irrigation method will have its disadvantages, in the case of drip irrigation, the drip irrigation pipe is often clogged. Today, Orientflex summed up several reasons for clogging of drip irrigation pipe often blocked, as well as solutions, you can learn quickly.
There are three reasons for clogging drip irrigation pipes:
(1) Sediment clogging
It is mainly caused by chemical fertilizer and water quality precipitation. First, after drip irrigation fertilization, some fertilizers remaining in drip irrigation pipes will precipitate, such as calcium sulfate, which will block the emitter flow channel. Second, if the drip irrigation water is hard water with high carbonate content, long-term use will generate more scale on the inner pipe wall of the drip irrigation and block the emitter.
(2) Physical clogging.
This is the main cause of drip irrigation clogging. The water quality of irrigation is poor, and the filtration system is not perfect. After sediment and other sundries are pumped into the pipeline and drip irrigation pipe, when they pass through the serrated flow channel of embedded emitter, sundries will block the flow channel and make the emitter unable to get out of water.
- Biological clogging.Crop roots invade drip irrigation outlets, or plug up caused by the growth of algae and other microorganisms in irrigation water. The water orientation and uneven irrigation of crop root will cause the root to grow into the water outlet of drip irrigation, and then extend into the water outlet and cause blockage. If the irrigation water is rich in algae and other organisms, the drip irrigation system is often combined with fertilization irrigation, and the light-shelter facilities such as fertilizer pond are not in place, it is easy to cause a large number of microorganisms, and the inner wall of drip irrigation will be covered and clogged.
Encounter the above clogging phenomenon, we must solve in time.
According to the water quality and flow, in the water pump inlet with wire mesh for 3 barriers, the number of installed barriers from small to large, can effectively stop suspended mud sand and debris, reduce physical clogging.
Filter system and drip irrigation pipe can also be reasonably installed. According to the water quality condition after pretreatment, sand filter, stacked filter, sieve filter or combination should be installed separately for filtration treatment, so that the water quality can generally meet the usage standard of drip irrigation.
For example, the safety performance of drip irrigation system can be greatly improved by installing a small flow screen type filter behind the shed head valve for secondary filtration treatment.
When the drip irrigation pipe is installed in the field, the hole on the drip irrigation pipe is upward, so that a small amount of impurities in the water can be deposited at the bottom of the pipe, and the root system can be prevented from invading the drip irrigation hole.
In addition, even chemical prevent clogging, usable acid is cleaned, achieve at the same time disinfect, inhibit and eliminate the effect of algae and microorganism in water. However, this method is easy to cause soil acidification, we should be careful to use!
