Abstract

Abstract: Under the control of open top chamber (OTC), rice “Guangliangyouxiang 66” was tested to simulate heat damage during heading and early grain filling periods. The relationship model of heat damage and yield reduction was established, and its accuracy was verified by field investigation data. Based on the historical observation data of the highest temperature of each day between July 16th and August 31st from 1981 to 2016, the Weibull model was used to establish the heat damage risk distribution model of the pilot counties. Subsequently, according to these two models, a variety of pure premium rate scheme of the pilot counties was determined in different deductible excess and insurance period, for providing various choices. The results showed that, 20 days after initial flowering period was the optimal insurance period length of heat damage insurance about heading and early grain filling periods. The pure premium rate achieved the lowest value when flowering in late July, and decreased gradually with flowering delay. Between different regions, pure premium rate fluctuated greatly, in which, the high value regions of pure premium rates are in the mountainous regions of southeast of Hubei province such as Xian’an, Chibi, Xishui and Macheng, and the humpy ground in northern Hubei, such as Xiangyang and Suizhou, were divided into low risk area.

Key words: Weather index insurance, Heat damage, Middle-season rice, Weibull distribution, Pure premium rate, Seed setting rate
