摘要
在总结水稻生育期生态规律研究成果的基础上，提出了一个水稻发育速度的优化模式。该模式综合考虑了温度和日长对水稻发育速度的影响，经回代检验，预报效果良好。以模式为依据，用全国主要稻区１６５站１９５１～１９８０年的光温资料求算早、中、晚稻的生育期，并绘出生育期日数的距平百分率空间分布图，据图分析我国水稻生育期的时空变化规律并解释其生态原因。
An optimal model was presented for rice developing rate by means of generalizing concerned research findings. The model, involving the integral impact of temperature and day length on rice developing rate, was tested and gave good predictions. The growing period was outputted from the model for early ,middle and late season rice respectively for 165 stations throughout the country with temperature data collected from 1951 to 1980. The relative mean deviation from the averaged growth duration over the time and then the stations was indicated for each station on a regional map, from which temporal and regional variations of the growing period were ecologically explained.
