本文运用农业气象统计方法,根据菠萝的生物学特性,求算出与广西南部菠萝气象产量相关密切的气象组合因子,作为菠萝平流寒害和霜毒指标,同时分析两种寒害天气类型的分布规律。在此基础上,以寒害指标作为预报对象,选取大气环流和气象因子,分别建立了平流寒害预报模式、平流寒害出现时段预报模式和霜害预报模式。
Based on the biological characteristics of pineapple, this paper calculated the meteorological composition factors closely related to the meteorological output of pineapple in southern Guangxi as the index of cold pineapple and frostbite in pineapple, and analyzed the distribution of the two types of cold weather. On the basis of this, taking the indicator of chilling injury as the object of forecasting, we select the general circulation and meteorological factors to establish the forecasting pattern of advection chilling hazard, the forecasting pattern of adventitious advent of chilling hazard and the frost forecasting model respectively.
