| 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 conducted at 13 experimental points in 12 provinces in the country, it has been proved that the mean daily temperature in grain-filliing stage can be the major meterological factor affecting rice comprehensive qualities,and that relation between the mean daily temperature and rice comprehensive qualities appears to be the quadratic equation,and that the early and the middle fillingstages are the temperature susceptible time section which can determine the good or poor comprehensive qualities of rice varieties. |
