| 摘 要： | 通过全国１２个省的１３个试点进行的多品种多播期试验，研究证明结实期日均温是影响稻米综合品质的主要气象因子；两者间呈二次曲线关系；结实前、中期为决定稻米综合品质优劣的温度敏感时段。

| Abstract: | Based on the tests of more rice varieties with many sowing dates con-ducted at 13 experimental points in 12 provinces in the country, it has been proved thatthe mean daily temperature in grain-filliing stage can be the major meterological factoraffecting rice comprehensive qualities,and that relation between the mean daily tempera-ture and rice comprehensive qualities appears to be the quadratic equation,and that theearly and the middle fillingstages are the temperature susceptible time section which candetermine the good or poor comprehensive qualities of rice varieties. |
