The heat resistance of 311 rice cultivars were identified in this paper, and 57 rice cultivars with high heat resistance were selected. Meanwhile, four pot experiments with different heat resistance rice cultivars were conducted, mainly including the effect of early earing of different rice cultivars by early sowing and transplanting, the relationship between fertilizer management and ability of heat resistance, the response of trace elements and plant regulators on rice seed setting rate under high temperature stress. Finally, the author put forward some techniques to relieve the high temperature stress, to guide the rice production of disaster prevention and mitigation in Southwest China.
