  2. Based on those, the concept of chilling process was put forward according to the lowest biologic temperature of main tropic and south sub tropic crop and fruit in guangdong and the low temperature ( environment temperature 5. 0 ) which is harmful to those crop and fruit. with the lowest air temperature ( the daily lowest air temperature ) x1, the lasting days of low temperature x2 and an integrative physical element - - negative accumulated temperature x3 in which the effect of the intense and lasting days of low temperature were considered, the correlation coefficient of those indexes were calculated and analyzed, and the results showed that there are apparent linear correlations among them

    在此基礎上,以廣東主要熱帶南亞熱帶作物的生物學下限溫度為依據,從這些作物受寒害的起點溫度(環境溫度5 . 0 )出發,提出了寒害過程的概念,並用寒害過程低溫的強度(逐日最低氣溫) x _ 1 、低溫的持續時間(天數) x _ 2及考慮了低溫的強度和持續時間綜合作用的物理量負積溫x _ 3這3個指標來描述寒害的強度,研究了廣東歷年冬季寒害的變化,分析了這3個指標間的相關系數,結果表明它們之間互相存在顯著的相關關系。
