Abstract

Abstract:

【Objective】 The key factors affecting cotton seedling emergence in saline-alkali land in southern Xinjiang were analyzed through regional field investigation, and then the measures for seedling preservation were put forward. 【Methods】 Literature investigation, field investigation and field experiment were used. 【Results】 Soil salinization intensity, abnormal climatic conditions, soil environment and water resources shortage were the main influencing factors for cotton emergence in saline-alkali land in southern Xinjiang. Proper seedling protection measures can increase the seedling emergence rate, broaden the adaptability of cotton in saline-alkali land, and then guarantee the cotton yield. 【Conclusion】 The saline-alkali resistance of cotton was improved by soil amendment, irrigation strategy and oxygen augmentation technology.

Key words: saline-alkali land; cotton; put forth seedlings; Influence factor; keep seedlings alive

摘要：

【目的】通过区域田间的调研分析影响南疆盐碱地棉花出苗的关键因素,进而针对性地提出保苗措施。【方法】采用文献调研、实地调研方式结合田间试验方法。【结果】壤盐碱化强度、异常的气候条件和土壤环境、水资源短缺是南疆盐碱地棉花出苗主要的影响因素。合适的保苗措施能增加出苗率,拓宽棉花在盐碱地的适应性,进而保障棉花产量。【结论】采取土壤改良剂、灌溉策略、增氧技术等综合措施可提高棉花苗期的抗盐碱能力。
