| 摘 要： | 在黑龙江省北纬Ｎ４６～４８°区域试种冬小麦，五年试验表明，以高越冬率为指标，分蘖节处于可溶性糖等光合产物峰值区的分蘖盛期，为抗寒的最佳状态，分蘖盛期分蘖节可溶性糖含量的高低，亦可为品种抗寒性选择的评价尺度。由于根前区对低温比分蘖节更为敏感，使冬小麦根前区位于温度和对稳定的３０ｃｍ地层以下，应是采取适当栽培的调控措施的目的。 |

| Abstract: | The cold-resistance of winter wheat (46-48 N),which is attempted in areas of Heilongjiang Province (46~48 degrees north),is determined by the ratio of surviving the winter.The period of tillering vigorously in which tillering nodes are within the summit point of solubility carbohydrates and other photosynthetic products is the proper state for winter wheat .The content of solubility carbohydrates during this period is another factor to determine the cold-resistance. Since the frontal part of roots is more sensitive to low temperature than tillering nodes,the purpose of adopting proper cultivation and adjustment measures is to keep the frontal part of roots 30 cm underground,where the temperature is relative stable. |
| Keywords: | the cold area in northern China winter wheat the surviving ratio after the winter |
