Abstract: 【Objective】 This study aims to study the effects of drip seedling emergence on soil salt characteristics and cotton growth in cotton field in southern Xinjiang under the condition of no irrigation in winter and spring. 【Methods】 Xinluzhong 67 was taken as the test material, three seedling emergence water quantities, 150 m³/hm² (W₁), 300 m³/hm² (W₂) and 450 m³/hm² (W₃) respectively, were set to observe the dynamic changes of soil pH and salt content, cotton seedling emergence rate, agronomic characters, dry matter accumulation characteristics and yield characteristics. 【Results】 The pH of topsoil treated with W₃, W₂ and W₁ decreased by 0.57, 0.43 and 0.19, respectively at the seedling stage, and the salt content decreased by 44.19%, 38.70% and 28.72%, respectively, but the salt washing effect decreased gradually after the full bud stage.The emergence rate of W₂ treatment was 87.31%, which increased by 11.44 and 5.78 percentage points respectively compared with W₃ and W₁.The greater the amount of seedling emergence water, the greater the index value of cotton agronomic characters.The plant height and stem diameter of W₃ treatment increased by 2.71%, 8.31% and 5.15%, 8.18%, respectively compared with W₂ and W₁.The average leaf area index (LAI) of W₃ treatment increased by 7.57% and 11.46%, respectively compared with W₂ and W₁.The total dry matter accumulation of shoot treated with W₃ increased by 5.55% and 7.75%, respectively compared with W₂ and W₁.The dry matter distribution coefficient of stem was W₁ > W₂ > W₃, and that of leaf and reproductive organ was W₃ > W₂ > W₁.The amount of seedling emergence water had a certain impact on the number of bolls per plant, but had little impact on the boll weight and lint percentage.The number of bolls per plant, boll weight and lint percentage of W₃ treatment were the largest, but the harvested density of W₂ treatment was the largest, and the final yield of W₂ treatment was the highest, but there was no significant difference with W₃ treatment. 【Conclusion】 Higher seedling emergence water can significantly reduce the pH value and salt content of soil surface during seedling emergence, promote the growth of cotton plant and the effective accumulation of dry matter, which is conducive to the formation of yield components per plant.However, too much irrigation will affect the seedling emergence rate.The yield is higher when the seedling emergence water of drip irrigation is 300~450 m³/hm².
