洞口蜜桔气候品质及气象条件分析

Analysis of Climate Quality and Meteorological Conditions of Dongkou Orange

为探究邵阳市洞口县雪峰蜜桔品质及其与气象要素的关系,采用相关性分析法分析各气象要素与各品质指标的相关性,根据柑橘品质标准判定洞口蜜桔品质,根据湖南省现代农业温州蜜桔种植适宜性气候区划指标对洞口蜜桔进行气候区划。结果表明:近5年洞口蜜桔品质均为优等;气候条件均在适宜及以上;长期气候区划为最适宜区。在影响洞口蜜桔品质的各类气象要素中,10℃以上积温和昼夜温差对其影响最大,其次是平均相对湿度、降水量、积温、日照时数和平均气温。筛选出的品质指标为可溶性固形物、可食率、横径,与上述气象要素均有一定相关性。通过研究以期为开展洞口蜜桔气候品质认证工作打下基础,进一步推动洞口蜜桔果业发展。

To explore the Shaoyang dongkou orange quality and its relationship with meteorological elements,this study analyzed the correlation between meteorological elements and quality indexes with correlation analysis.Determined the quality of dongkou orange according to the citrus quality standard,and made climatic regionalization according to the climate zoning index of the suitability of modern agriculture for orange planting in Wenzhou of Hunan province.The results showed that,the quality of dongkou orange were all excellent in recent 5 years,the climatic conditions were suitable and above,and long-term climatic regionalization was the most suitable area.Among all kinds of meteorological factors affecting the quality of dongkou orange,the accumulated temperature above 10℃and the day-night temperature difference had the greatest influence,followed by the average relative humidity,precipitation,accumulated temperature,sunshine hours and average air temperature.The selected quality indexes were soluble solid,edible rate and the fruit diameter,which were correlated with the above meteorological factors.So as to lay a foundation for the certification of climate quality of dongkou orange and further promote the development of dongkou orange industry.
