Effects of Organic Polymer Compound Material on K⁺ and Na⁺ Distribution and Physiological Characteristics of Cotton Under Saline and Alkaline Stresses.

ABSTRACT: Soil salinization and alkalization greatly restrict crop growth and yield. In this study, NaCl (8 g kg^-1) and Na₂CO₃ (8 g kg^-1) were used to create saline stress and alkaline stress on cotton in pot cultivation in the field, and organic polymer compound material (OPCM) and stem girdling were applied before cotton sowing and at flowering and boll-forming stage, respectively, aiming to determine the effects of OPCM on K⁺ and Na⁺ absorption and transport and physiological characteristics of cotton leaf and root. The results showed that after applying the OPCM, the Na⁺ content in leaf of cotton under saline stress and alkaline stress were decreased by 7.72 and 6.49%, respectively, the K⁺/Na⁺ rati
