| 摘 要： | 以曼谷、清迈（泰国）、密支那（缅甸）1980～1997年逐日4时次气温观测资料为基础，并用NCEP／NCAR再分析资料通过回归分析补全缺测值，通过Cressman插值法得到河内（越南）的同期逐日气温序列，结合四地理论日长计算结果和用国内分期播种资料计算的培矮64S的育性转换指标集及发育期模型，对其在东南亚3国的育性气候适应性进行了分析，并给出了90％、95％、100％保证率下安全制种和繁殖的最早、最晚播种期，计算了相应的风险概率。 |
| 关 键 词： | 培矮64S 稳定不育期 稳定可育期 育性风险概率 |

| Abstract: | On the basis of temperature data four times per day from 1980 to 1997 in Bangkok and Chiengmai, Tailand, Myitkyina, Myanmar, using NCEP/NCAR re-analysis temperature statistics the missing observation was supplemented. By Cressman Interpolation, we got temperature data in Hanoi, Vietnam. In terms of calculations of theoretical daylength and fertility conversion index as well as developmental model of Peiai 64S, we analyzed climatic adaptation of fertility of Peiai 64S in Bangkok,Chiengmai, Myitkyina and Hanoi, representative areas of rice production in Tailand, Myanmar and Vietnam respectively, and described the earliest and latest sowing date of safe seed production under assuranee of 90% ,95% and 100%. |
