中文摘要: 针对杂交水稻制种对晴、雨天气敏感反应，根据建阳市（1961－1996年）降水资料，分析降水分布规律，采用历年6－9月逐日、各候连阴雨天气概率分布规律和连续10天内遇阴雨天概率分布谷期，确定闽北地区杂交水稻制种的最佳期。
中文关键词: 杂交水稻，制种，连阴雨，概率
Abstract:In view of the male and female rice being sensitive to the clear and rainy weather in hybrid rice breeding,the continuous overcast or rainy weather that lasting 3 days or more is studied in terms of probability distribution by using the rainfall data (1961 — 1996) of Jianyang city. And the probability of occurance of overcast or rainy weather mentioned above during a period of ten days is also studied similarly. The best period of hybrid rice breeding in Northern Fujian is then settled.
