Crop land surface is more complex, there may be ploughed stones, harvested sharp straw may scratch PVC lay flat hose. So ordinary PVClay flat hose will inevitably wear and leak in long-term use. Although the leaked water is also left in the fields, it is easy to make some areas over-irrigated. PVC lay flat hose tells you that there is no good irrigation in front of you, and once the pipe wall wears out, it will cause the whole pipe wall on more than a dozen meters to be useless. Because the water pressure must be very high to transport water from a long distance, it is impossible to close the gap in a common way similar to the way of repairing the tire.
Fine hydrolysis is not nearly thirsty. Compared with the usual trickling water of PVClay flat hose, if you can’t understand the near thirst in the field in a dry day. Maybe just after it was sown, it was sucked up by the cracked land. Compared with the same period, the emission of PVC lay flat hose is larger, at least more than four times that of ordinary PVC lay flat hose, which can be seen from the caliber. With such a large displacement of PVC lay flat hose, it can not be used for repeated work in irrigation. Thus, such a PVC lay flat hose is very necessary for irrigation work.
