对杂交水稻花时习性及花时相遇状况与各温湿度因子及其温湿互作配比的相互关系的统计分析表明：开花当天及其前一天的平均温度对花时的影响较大，湿度对花时的影响因温度不同而不同；制种的父母本花时受温湿度影响程度有一定的差异；花时同步指数与温湿配比之间存在着二次抛物线回归关系，并给出了其最优回归方程。不同温湿互作配比下的比较研究表明，相对湿度在温度较高时对花时相遇的影响更大，高湿在温度较高时有利于母本花时提前和集中，却使父本花时相对延迟。
The statistical analysis of the interrelationship between flowering time and flowering time, temperature and humidity factors and the interaction between temperature and humidity of hybrid rice showed that the average temperature on the flowering day and the previous day had a great influence on the flowering time, the humidity The effect on flowering time varies with temperature. The parents and parents of flowering plants have some differences in the degree of temperature and humidity affected by temperature and humidity. There is a quadratic parabolic regression relationship between flowering time synchronization index and temperature-humidity ratio, The optimal regression equation. The comparative research under the different temperature-humidity interaction ratio shows that the relative humidity affects the flower-time more when the temperature is higher, while when the temperature is high, the high humidity will favor the female parent to advance and concentrate, Spending time is relatively delayed.
