Have you found that many blueberry growers use white PE pipe to irrigate in Yunnan Province of China?
Actually, what they use is white outside and black inside pipe. So what are the benefits of using such a PE pipe?
On the one hand, the advantage of the white outer layer is that it can reflect sunlight, and it absorbs less heat compared to black, which can reduce the temperature of the water stored inside the pipe. So when water is released, it will not scald the root system.
On the other hand, it is sun-proof and has good anti-aging properties, which can extend the service life of the pipe.
And why the inside of tube is black?
Because the black inner layer can prevent light from entering the pipe, it can effectively prevent the growth of algae in the pipe and avoid the clogging of the nozzle or dripper.
