【Abstract】 Models of temperature in different areas above sea level were founded through the climatic data for 30 years and geographical information. On the basis of this, the probabilities of climatic risks were calculated and climatic riskfs of two-line hybrid seed production were assessed with the special analysis method. Optimum times and areas were found in Hefei and it was significant for two-line hybrid rice seed production.更多还原
