The rice flowering phase is the most sensitive phase to high temperature effects. At present, measures for shifting the sowing period to avoid the high temperature of the rice in the flowering period are proposed, however, due to the shifting of the sowing period and the continuous rising of the temperature, the high temperature has great influence on the development of rice ears. In addition, the selection of heat-resistant rice varieties is an effective measure against high-temperature damage, but the heat-resistant varieties are also affected by high temperature to some extent due to the rising temperature.
The main cause of glume degradation at high temperatures is endogenous metabolic disorders. Under the condition of extremely high temperature, the damage of high temperature to the formation of rice ears and seed setting and the damage of high temperature to rice seeds can be reduced to the maximum extent by combining the measures of variety and sowing period adjustment, irrigation and spraying of an exogenous regulator.
