摘要： Context: Xinjiang, located in northwestern China, has emerged as the predominant cotton-growing region in China and one of the world's largest cotton producers. Despite its arid climate, limited water and heat resources, and prevalent soil salinity issues, Xinjiang has undergone a remarkable transformation in cotton production over the past three decades. Through continuous advancements in cotton cultivation techniques, there has been a consistent improvement in cotton yields, rising from an average of 1500 kg ha -1 during 1995-2000-1800 kg ha -1 during 2006-2010, and further to 1950 kg ha -1 during 2016-2020, achieving a remarkable "triple jump." Methodology: This review employed a comprehensive methodology, including literature reviews, statistical data retrieval, consultations with experts and local officials, and interviews with cotton farmers. An analysis of the historical development of cotton cultivation techniques in Xinjiang identified three generations (3Gs) of cultivation technology systems: "close planting, dwarfing and early maturation" system, "drip irrigation-based fertigation" system, and "light, simplified, and high-efficiency" system. A systematic assessment was conducted, evaluating the performance and contributions of these technologies, accompanied by a multidimensional interpretation of the underlying mechanisms. Results: The cultivation technology systems in Xinjiang have progressed over three generations, each focusing on different aspects and building upon the previous one. The first-generation (1 G) system emphasized the effective utilization of light and heat resources, while the second-generation (2 G) system aimed to improve water and fertilizer use efficiency. The third-generation (3 G) system prioritized achieving cost-effective cotton production. These region-specific systems facilitated the integration of agronomic techniques and mechanization, ensuring the efficient utilization of resources. As a result of these advancements, cotton yield and profitability in Xinjiang have consistently increased, making a significant contribution to high-yielding and efficient cotton production in Xinjiang. Conclusion: The adoption of three generations of distinctive Chinese cotton cultivation technology systems has efficiently harnessed resources, propelling Xinjiang's cotton yield to global prominence. This review provides valuable insights into the underlying principles and inevitability of the 3Gs in Xinjiang. Moreover, it serves as a reference and inspiration for other countries aiming to advance their own cotton cultivation techniques.
