Study on Chinese Wheat Planting Regionalization(II)

To make planting regionalization serving wheat research and production better,massive investigation was conducted and information was collected,the experiences of the author on wheat cultivetion and production were integrated,the Chinese wheat planting regionalization was put forward based on the previous research.The Chinese wheat planting region was divided into 4 main areas,namely: the northern winter(autumn sowing) wheat-production areas,the southern winter(autumn sowing) wheat production areas,spring(autumn sowing) wheat-production areas,the southern winter(autumn sowing) wheat production area,spring(spring sowing) wheat production area and the winter-spring wheat production area,which was further divided in to 10 sub-districts,namely: the northern winter(autumn sowing) wheat area,the Huang-Huai winter(autumn sowing) wheat area,the middle and lower reaches of yangtze China winter(Late autumn sowing) wheat area,the Northeast spring(sowing) wheat area,the northern spring(sowing) wheat area,the northwest spring(sowing) wheat areas,the Xinjiang winter-spring wheat area and the Qinghai-Tibet spring-winter wheat areas.The geographical scope of the district,climatic conditions,soil type,planting system,wheat production situation,pest and disease incidence and wheat production technology requirements in each area were briefly elaborated.
