广西贺州市脐橙种植气候区划

Climatic Regionalization of Naval Orange Planting in Hezhou City of Guangxi

与国内外脐橙优产区相比,贺州市热量条件对脐橙生产更具优势。但复杂的地形地貌使市内各地在湿度、最高气温等气候要素差异较大,影响当地脐橙产量及品质。通过分析贺州市气候特点,结合脐橙生长发育对气候条件要求,确定了贺州市脐橙适宜种植气候指标,在GIS技术下绘制出贺州市脐橙适宜种植气候区划专题图。通过对专题图中的最适宜、适宜、次适宜、不适宜区气候区域气候论述,为贺州市脐橙生产的优化布局提供气候依据。

As compared with domestic and abroad planting region of Naval orange,there was favorable thermal condition for Naval orange growth in Hezhou City,but the difference of climatic factors such as relativity humidity,highest temperature and so on were caused by complex terrain and physiognomy,which had an influence on the yield and quality of Naval orange in local.Through the analysis of the climatic characteristics of Hezhou City,according to the requirement of Naval orange growth for climatic conditions,the suitable climatic indexes for Naval orange planting was confirmed and the special map of suitable region for Naval orange growth was drawn with GIS technology.Moreover,the discussion on the climatic of the optimal,fitting,general and unfitting regionalization based on the map information can provide scientific climatic basis for the optimization distribution of Naval orange production in Hezhou City.
