摘要
通过分析甘肃省棉花生产发展、布局演变和植棉区自然、气候特点等,按照"区域划分同一性"原则,以≥10℃活动积温、7月平均气温、无霜期为主要依据,在全国棉花生产一级区划的框架下,将甘肃省棉花生产划分为黄河流域棉区黄土高原亚区、黄河流域棉区特早熟亚区和西北内陆棉区河西走廊亚区3个二级区;中部沿黄灌区特早熟次亚区、陇东特早熟次亚区、河西走廊早熟棉次亚区和河西走廊特早熟次亚区4个3级区。通过分区评述各级区的气候、生产等特点,指出了在该区发展棉花生产的优势、不利条件和自然灾害,提出了棉花产业发展的思路:如合理规划产业布局,优化种植区域与结构;坚持集中连片,突出规模效益;坚持依靠科技创新,突出经济效益;实施产、学、研相结合,育、繁、推一体化的模式;加强人才队伍建设和科技培训;增加和整合支农投入。
This paper examined the historical evolution, natural and climatic characteristics of cotton production in Gansu Province. According to the ＂production zoning with similarity＇principle, the active accumulated temperature above 10℃, mean temperature in July, and frost-free period, and under the national framework of first-tier cotton production zone, the cotton production zone in Gansu Province should be divided to the second-tier zones, including Hexi Corridor sub-region of northwest inland region, Loess Plateau sub-region of Yellow River region, and extra early-maturing sub-region. Furthermore, it was divided into 4 third-tier regions including early-maturing cotton region of Hexi Corridor, extra early-maturing cotton region of Hexi Corridor, extra early-maturing cotton region of middle Yellow River irrigation region, and Londong extra early-maturing cotton region. This paper also pointed out the advantages, disadvantages, and possible natural disasters of cotton production in Gansu Province. Finally, this paper provided some suggestions for the future development of cotton production in Gansu Province, including 1） to adopt reasonable zoning plan; 2） to optimize planting area and structure; 3） to increase production scale to achieve scale economy; 4） to encourage technology progress and innovation; 5） to integrate production, learning, and research, 6） to combine breading, reproduction, and extension; 6） to attract more experts and professionals and provide more trainings; and 7） to increase investment to support cotton production.
