ABSTRACT = {This study adopted the method of barrel planting to artificially set the
salt content of six different soils (CK:1.5 g kg-1
, T1:3.0 g kg-1
, T2:4.0 g kg-1
, T3:5.3
g kg-1
, T4:6.2 g kg-1
, T5:7.3 g kg-1
) to study the effects of different degrees of mild
salt stress on photosynthetic physiology, growth index and yield of cotton under
drip irrigation. The results showed that with the increasing salt stress and the
prolongation of stress time, the photosynthetic physiological indexes of cotton
showed a downward trend (P < 0.01), and the plant height and leaf area were
significantly affected by salt stress in the early growth stage. Furthermore, the
comprehensive analysis showed that compared with moderate and severe salt
stress, stomatal limitation was the cause of photosynthetic rate decline in cotton
under mild salt stress at early growth stage, while non-stomatal limitation was at
late growth stage. Photosynthetic parameters were closely related to the degree of
salt stress, and cotton yield showed a good correlation with photosynthetic
indicators. This experiment could provide a theoretical basis for the cultivation
and management of cotton in mild saline-alkali land in Xinjiang.},
