Abstract

Abstract: A rice planting demonstration county in central of Hunan-Shuangfeng county was selected as a pilot, using daily weather observation data, rice yield and rice observation data of agricultural meteorological observatories from Shuangfeng county from 1989 to 2018, combined with the main types of agrometeorological disasters during the growth period of rice, the meteorological disasters with large impact on production were identified as insurance hazard factors to design the meteorological insurance index.The research showed that the high temperature heat damage was the main meteorological disaster that caused single cropping rice yield reduction in central of Hunan. High temperature heat damage meteorological insurance index was established based on the comprehensive hazard heat accumulation temperature and the number of continuous days; By calculating the rice production reduction and currency loss caused by meteorological disasters over the years, the compensation trigger coefficient and compensation standard of the high temperature heat damage meteorological insurance index were determined.

Key words: high temperature heat damage, single cropping rice, agricultural insurance, meteorological index
