气象条件对柑桔果实膨大速度的影响

Influence of Meteorological Conditions on Fruit Inflation Velocity of Orange

根据2003-2004年柑桔果实膨大观测资料和相应的气象资料,对无灌溉条件下,降水、气温及日照等气象因子对柑桔果实膨大速度的影响进行了分析和研究。结果发现:降水与果径增长量呈显著的正相关;气温与果径增长量也有明显的线性关系,当日平均气温≤30℃时,果径增长量与气温呈显著的正相关;当日平均气温高于30℃时,果径增长量与气温则有负的相关关系;日照的影响分两种情况:当气温、降水都适宜时,果径增长量与日照有正的相关关系;当出现高温干旱等气象灾害时,果径增长量与日照呈显著的负相关。

Based on observation data of the orange fruit inflation and meteorology during 2003 - 2004, the influence of the meteorological factors, such as precipitation, temperature and sunlight on the fruit inflation velocity of orange without irrigation was studied. The results showed that the precipitation was positively related to the inflation of fruit diameter significantly, while there was an obvious linearity relation between temperature and the inflation of fruit diameter. When the average daily temperature was lower than 30cC , there existed a notably positive correlation between temperature and the inflation of fruit diameter, while there was negative correlation when the temperature was higher than 30cC. Moreover, the influ- ence of sunlight had two aspects. There existed an evident positive correlation between sunlight and the inflation of fruit diameter in the condition of the suitable temperature and precipitation, while there existed an evident negative correlation with the disaster of the high temperature and drought.
