高原号春小麦品种生态适应性研究

Study on Ecological Adaptation of "Plateau No." Spring Wheat

对高原号春小麦品种在内蒙古科尔沁沙地（奈曼旗）品种比较试验结果进行了产量—天气气候分析；测算了光合生产潜力、光温生产潜力和光温水生产潜力；测定并分析了这些品种的光合生理特性。结果表明，大部分高原号春小麦品种利用当地气候资源的有效系数大于０．７。

Data from a variety comparison trial of 'Plateau No.' spring wheat varieties conducted in Ke erqin sandy field in Naman county of the Inner Mongolia Autonomous Region were used to analyse yield weather and climate. The analyses included photosynthetic production potential and production potential of light, temperature and rainfall. The results indicated that most of 'Plateau No.' spring wheat varieties had over 0.7 effective coefficient of using local climatic resources. It proved that these varieties could be adapted to the natural ecological conditions in Naman county. This research provided scientific basis for application and extension of these varieties in the similar areas. It added data for study of wheat ecological adaptation.
