Embodiment Construction

[0037] The present invention takes the determination of the net premium rate of low-temperature disaster weather index insurance for grapes in Nanjing area as an example.

[0038] Such as figure 1As shown, the artificial control experiment design was firstly carried out, and the grapes in the facilities with consistent growth were selected for low-temperature treatment, and then the normal growth resumed after treatment. Experimental plan for low temperature treatment: select 10 potted grapes, design the daily minimum temperature at 0°C, 3°C, 6°C, 9°C, and 11°C, and design the daily maximum temperature at 28°C; the duration of treatment is 2, 4, 6, and 8 day; take the daily maximum of 28°C / daily minimum of 18°C ​​as the control. After the low-temperature treatment, put the grapes into the facility greenhouse to continue growing until harvested. Monitor the microclimate data of the facility greenhouse in real time in the facility greenhouse. If the daily minimum temperature i...

Abstract

The invention discloses a method for determining a protected grape low-temperature disaster weather index insurance pure premium rate. The method comprises the following steps of: (1) carrying out low-temperature processing of different levels on protected grapes; (2) calculating output loss rates of the protected grapes under different-level low-temperature processing; (3) constructing a probability distribution model of low-temperature disaster weathers; (4) establishing a output loss rate model; and (5) calculating the insurance pure premium rate. According to the invention, the weather index insurance pure premium rate under the low-temperature disaster condition is accurately obtained, and the measurement precision is high.

Description

technical field [0001] The invention relates to a calculation of insurance premium rate, in particular to a method for determining the pure premium rate of facility grape low temperature disaster weather index insurance. Background technique [0002] Grape( Vitis vinifera ) belongs to deciduous vines, has the title of "God of Fruit", and is one of the most important fruits in the world. The world's grape production accounts for about 1 / 4 of the total fruit production. In recent years, protected cultivation of grapes in China has developed very rapidly. In 2014, the national grape cultivation area has reached more than 3 million mu. Jiangsu is the main area for grape cultivation, with a cultivation area of ​​450,000 mu. Among them, the facility cultivation area reaches 100,000 mu. Since Jiangsu is located in a subtropical high-pressure monsoon climate zone, unfavorable meteorological conditions such as high temperature, high humidity in summer, low temperature in winter and...
