根据广东省大陆小麦生育期间20年的气候资料和29个品种2年生态学试验数据,用计算机以聚类法定量分区,将隶属华南早熟麦区的广东省划归为6个小麦生态亚区。指出各区主要农艺和产量性状控制指标,为小麦生产发展、品种布局及栽培技术改良提供理论依据。井探讨了小麦生态区划的若干原则、聚类法的应用要求和指标选择依据。
According to the 20 years’ climate data and the 2-year ecological test data of 29 cultivars during the growth period of wheat in mainland of Guangdong Province, we quantitatively partitioned the areas by cluster analysis with computer, and classified Guangdong as 6 wheat ecologically subregions . Pointed out that the main agronomic and yield traits control indicators in each district, providing theoretical basis for wheat production development, variety layout and cultivation techniques. We discussed some principles of wheat ecological zoning, the application requirements of clustering method and the basis of index selection.
