摘　　要：通过连续三年的水稻分期播种试验,对不同类型品种幼穗分化期的长短与温光生态因素的关系进行了探讨研究。结果表明,不同类型的水稻品种幼穗分化期的长短受日照时数和日均温的影响。与日照时数多少呈正相关,与日均温高低呈负相关。The author studied on the influence of hours of sunlight and average temperature in daytime on the polarization period of young rice spikes of different types based on a three-year trial planting of rice during the polarization period. The research indicates that there is a direct ration between the hours of sunlight and the lastingness of the polarizationperiod and there is an inverse ratio between the average temperature in the day and the lastingness of the polarization period.
