Risk Assessment of Meteorological Frost Disaster During the Blossom Phase of Qingyang Apple
摘要
Abstract
In order to provide references of local’s disaster prevention and mitigation, it is necessary to assess the risk of frost disaster during apple florescence. This paper used statistical method to analyze the observed data from of apple’s blossom date which were got from Xifeng Agricultural Experiment Station. The results showed that: the main hazard factor of frost disaster during the flowering phase of Qingyang apple, was the extreme minimum temperature of Xifeng during mid April to early May and Ningxian’s in April. These two factors’influence weights had achieved 24% and 76%, respectively. Then, we built an evaluation model of frost disaster during the flowering phase of Qingyang apple. Comparatively analyzed the frost disaster during the flowering phase of apple from 1990 to 2012 by the model, it showed that apple was frosted would be harmed lightly while its early blossom phase, but seriously while its final blossom phase or fruit bearing phase.关键词
