| 摘 要： | 预测水稻抽穗期对水稻安全生产和杂交育种工作起着非常重要的作用。应用AT-Tbase法（AT-accumulated effective temperature;Tbase-base temperature）预测水稻品种上育397的抽穗期。利用Tbase和有效积温，结合常年气象数据，可预测上育397在不同地区的安全抽穗期。当Tbase=9时，有效积温是597．2474℃，验证值与实际抽穗期的差异范围为-3～＋3d，预测值精确度最高。

| Abstract: | It was important of forecasting rice heading stage to rice safety production and cross breeding, The study of applying AT-Tbase method to forecast heading stage of Shangyu 397 was conducted. The safe heading stages in different districts could be forecasted according to Tbase, accumulated effective temperature and meteorological factors. The results indicated that when Tbase equaled to 9, the accumulated effective temperature was 597. 2474℃. Compared with the actual value, the difference ranged from-3 days to 3 days, the accurate rate achieved remarkable level. |
