摘要

Abstract

The correlations between the climatic factors in the whole growth period of IIYou 688 and the yield and yield components of this rice variety were analyzed. The results showed that the productive panicles showed a significant positive correlation with the maximum air temperature of mid - May, and a significant negative correlation with the sunshine duration of mid - August. There was a significant positive correlation between the setting percentage and the minimum air temperature during the first 20 days of September. The number of total grains per panicle was significantly positively correlated with the maximum air temperature of August. The number of filled grains per panicle had significant and extremely significant positive correlations with the minimum air temperature and average air temperature of mid -September, respectively. The yield had significant negative correlation with the rainfall during the first ten days of September. Therefore, the yield of IIYou 688 could be further increased by some technique measures, such as the adjustment of the planting season, the application of plant growth regulator etc.
