In recent years, high temperature have repeatedly occurred during flowering and fruiting stage of single season rice in the Yangtze River Basin. This study analyzed the characteristics of high temperature heat damage, and the effect of high temperature on seed setting rate during the flowering and fruiting stage of high temperature years. The analysis results indicated that the daily maximum temperature increased and the duration of high temperature extended. The daily maximum temperature in early July and early August of high temperature years raised by 4.3 ℃-4.8 ℃ compared with normal temperature years. During the flowering and fruiting stage of rice, when encountering high temperatures, the seed setting rate decreased by 28.2-43.4 percentage points. The resistance to high temperature heat damage was different among different varieties. According to the characteristics of high temperature heat damage in flowering and fruiting stage and the characteristics of high temperature caused the decrease of the seed setting rate, proposed four prevention and control measures for high temperature heat damage during flowering and fruiting stage, including high temperature warning and sowing period adjustment, selection of heat-resistant varieties, field irrigation during high temperature periods, and spraying of growth regulating substances.
