我国主产棉区棉花纤维品质区域特征明显,合理划分纤维品质生态区有助于提高原棉的纺纱品质.本研究采用GGE双标图的“环境-性状”功能图分析了2011—2015年期间国家棉花品种区域试验中传统棉区与纤维品质性状的互作,并提出了我国主产棉区棉花纤维品质生态区域划分.结果表明:我国主产棉区可划分为“优质纤维生态区”、“低马克隆值生态区”、“高比强度与马克隆值生态区”和“普通纤维生态区”.其中,优质纤维生态区包括长江上游和长江下游棉区,棉纤维长度、比强度、马克隆值等指标协调较好,且纺纱均匀性指数表现最好;低马克隆值生态区位于南疆和北疆棉区,马克隆值和比强度低,纺纱均匀性指数较好;高比强度与马克隆值生态区涵盖长江中游、南襄盆地和淮北平原棉区,比强度和马克隆值高,其余性状表现一般;普通纤维生态区包括华北平原和黄土高原棉区,各项纤维品质指标表现中等或较差.本研究应用GGE双标图的“环境-性状”功能图划分的纤维品质生态区可为优化我国棉花品质区域化种植和纺织企业合理用棉提供决策支持,也可为其他作物生态区划分提供方法参考.
The regional characteristics of the cotton fiber quality in the main cotton producing areas in China are obvious, and the reasonable division of the fiber quality eco-zones helps to improve the spinning quality of the raw cotton.In this study, the “environmental-trait” function chart of the GGE double- Year cotton area in the national cotton varieties and fiber quality traits in the regional trials and put forward the ecological quality of cotton fiber in the main cotton producing areas in China.The results show that the main cotton producing areas in China can be divided into “,” Low micronaire ecological zone “,” high-intensity and micronaire ecological zone “and” ordinary fiber ecological zone. "Among them, the high-quality fiber ecological zone includes the upper reaches of the Yangtze River and the lower reaches of the Yangtze River Cotton area, cotton fiber length, specific strength, micronaire and other indicators of coordination is better, and the spinning uniformity index performance is best; low micronaire ecological zone is located in the southern and northern cotton, micronaire and specific strength Low and uniform spinning index. The high specific strength and micronaire ecology area covered the middle reaches of the Yangtze River, Nanxiang basin and Huaibei plain cotton area, with high specific strength and micronaire value. North China Plain and the Loess Plateau Area, the fiber quality indicators of medium or poor performance.In this study, the application of GGE double plot ’environmental - characters’ functional map of the ecological quality of the division of the region can be optimized for the regionalization of China’s cotton quality and reasonable use of textile enterprises Cotton provides decision support, but also provides a methodological reference for other crop ecological zones.
