摘要
根据怀化2010~2015年连续6 a无灌溉条件下温州蜜柑的气象、作物平行观测资料,分析了温州蜜柑果实逐旬膨大量与日照、气温、湿润指数的相关关系,率先改进和建立了蜜柑膨大旬气候生产潜力模型,分析了果实异常膨大的气象原因。结果发现:温州蜜柑多年逐旬平均膨大量呈抛物线变化趋势,和日照、气温、湿润指数为显著的类抛物线多项式关系,和气候潜力呈显著的指数关系。影响果实异常膨大的主要气象因素是干旱、暴雨等异常供水情况,其次为寡照及高温天气。
According to the Huaihua 2010-2015 for 6 consecutive years meteorology and crop parallel observation data of Wenzhou sweet orange without irrigation condition, analyzed the relationship among amount of enlargement per every 10 days of Wenzhou sweet orange, sunshine, temperature and humidity index, taking the lead in establishing and improving the sweet orange enlargement with a period of 10 days meteorology and potential productivity model, the meteorological causes of abnormal enlargement of fruit were analyzed. The results showed that: Wenzhou sweet orange average enlargement amount per every 10 days for years showed a parabola trend, the sunshine, temperature and humidity index had significant parabolic polynomial relations with it, and the climate potential had a significant exponential relationship with it.The main meteorological factors affecting the abnormal enlargement of fruit were drought, rainstorm and other abnormal water supply, followed by the lack of light and high temperature weather.
