摘要
利用1953-2003年实测气象资料,通过与秭归地区脐橙种植的主要气候指标及脐橙生长发育所需的气候条件进行对比,分析了皖南山区的水热特点以及近年的变化趋势,评价了当地脐橙种植的气候适宜性。结果表明:与秭归相比,皖南山区的降水、日照条件相似,但热量条件差异较大;皖南山区≥10℃积温偏少影响脐橙品质,冬季极端最低气温过低是脐橙种植的主要限制因子;近年来气候变暖使得皖南山区的热量条件有所改善,对提高脐橙品质有利,但冬季热量条件与脐橙安全越冬的要求还有相当距离。因此,目前脐橙在皖南山区只能利用暖坡地带有限种植,还要注意防范冬季冻害和伏秋旱。
Based on the observed meteorological data from 1953 to 2003, the main climate indices and the required climate conditions for umbilical orange growth and development were compared in the mountain areas of South Anhui Province and Zigui of Hubei Province. The water and thermal conditions and their changes in recent years in the mountain areas of South Anhui Province were analyzed. The climate suitability for umbilical orange planting in mountain areas of South Anhui Province was assessed. The result indicated that precipitation and sunlight conditions in the two areas were similar, while the thermal conditions in the mountain areas of South Anhui Province was worse than in Zigui of Hubei Province. The insufficient accumulated temperature of ≥ 10℃ influenced the fruit quality of umbilical orange. The main restricted factor for umbilical orange planting was too low extreme lowest temperature in winter in mountain areas of South Anhui. Thermal conditions still did not meet the needs for a safe over - wintering of umbilical orange, although thermal conditions had been improved due to climate change. Therefore, the umbilical orange could only be planted in the warm sloping fields. The frozen disaster in the winter and drought in the summer and autumn was still needed to prevent.
