摘要

Using the daily meteorological data from 1957 to 2015, the time series data of millet yield from 1980 to 2015, and the investigation and previous studies of meteorological disasters in Wuzhai County of Shanxi Province, the key meteorological disasters affecting the yield of millet at various growth phases is determined. Comparing the historical yield loss and main disasters, we construct synthetical weather indices such as rainstorm index P1+, freeze injury index T4-, drought index P1-, P2, P3-, P4- during key growing periods. A model for optimizing the relationship between weather indices and yield loss is proposed to quantitatively evaluate the impact of weather indices on crop yields. The synthetical weather indices insurance of millet is designed and then the premium rates and trigger values are given.
