Correlation plot between cotton growth indexes and water and salt content of 0-40 cm soil. * and ** mean significance level of 1% and 5%, respectively. The meaning of the abbreviations: SWC0-40 (average soil water content of 0–40 cm soil at the seedling stage), SSC0-40 (average soil salt content of 0–40 cm soil at the seedling stage), ER (emergence rate), EI (emergence index), VI (vitality index), PH (plant height), ST (stem diameter), LAI (leaf area index), Pnmax (maximum net photosynthetic rate), Rd (dark respiration rate), Ic (light compensation point), Isat (light saturation point), ΔI (the range of available light intensity). The gradient of the legend is a function of the strength of the correlation, while the slope of the ellipse indicates a negative or positive correlation (i.e., towards the right is a positive correlation, and towards the left is negative correlation). The shape of the ellipse indicates the strength of the correlation
