Effects of saline water drip irrigation on soil salinity ...

In extremely arid areas, the leaching effect of rainfall is weakened. When cotton is irrigated with saline water of salinity greater than 224 g l −1, the salt is accumulated at the main cotton root zone. The effect of salinity of irrigation water on cotton growth is a gradual process and is highlighted during the boll‐opening period.
