Abstract£ºTwo effective measures can be taken for salinity injury control to cotton (Gossypium hirsutum L.). One is to improve salinity tolerance of cotton plants, and the other is to avoid or alleviate salt stress. The methods and principles of improving salt tolerance and of avoiding or alleviating salt stress were commented. It is suggested that, besides saline soil improvement with engineering measures, comprehensive utilization of agronomic measures such as suitable cultivars, irrigation and fertilization, seed treatment, furrow seeding with plastic mulching£¬and induction of unequal salt distribution in the root-zone were effective to control salt-injury in cotton.
