      abstract = {Middle-season rice is an important food crop in southern  rice areas of China, especially in Yunnan, the main  rice-producing region. However, due to the impact of low  temperature at the seedling stage and high or low  temperature at the booting and heading stage of  middle-season rice, the yield is not stable.Based on the  data of yield factors of different middle-season rice  varieties planted in the same ecological site in Jingdong  County from 2009 to 2016, average development period was  calculated using the data of development period measured in  field during 2009-2016, and the average of meteorological  factors (daily average temperature, daily maximum  temperature, daily minimum temperature, and sunshine hours)  and total precipitation were calculated. The correlation  between meteorological factors in different development  periods of each year and corresponding per unit area yield  was analyzed. Temperature is the most important factor  affecting rice yield. Sufficient light is beneficial to the  increase in the number of grains per spike and thousand  seed weight in the sowing-seedling emergence stage and milk  maturity-maturity stage. Excessive precipitation will  reduce the number of grains per spike in the  booting-heading stage. Excessive precipitation decreases  the number of filled grains per spike in the  jointing-booting stage, and proper drainage helps increase  the formation rate of ears. In this study, the main  meteorological factors affecting rice yield were analyzed  to provide scientific reference for rice production and  management in this county in future.},
