摘要: 本文讨论了县级柑桔生态区划的方法.江山是浙江省新的柑桔产区,位于我国柑拮栽培的北缘。根据主要生态因子(地形、气候、土壤等),将该县划分为4个宽皮柑桔生态区。再根据柑估冬季受冻和夏季受早状况,划分为9个副区。

Abstract: Citrus trees (Citrus Linn) are important economic craps for south China. They must grow in warm and humid cimate. Freeze injury in winter is the main weather calamity of the northern fringe of citrus trees growing region of China. It affects the normal growth, development, output and quality of citrus.The method for ecological division of citrus trees in a county is discussed. Citrus trees are one of the typical frost tender plants in subtropical zone. Jiangshan County is a new citrus growing area of Zhejiang Province. It is situated at the northern fringe of citrus growing region. This county can be divided into four ecological areas of cultivating mandarin (Citurus reticulata) according to the major ecological factors (topography, climate, and soil), namely: near suitabe (Ⅰ), poor suitable (Ⅱ), possible growing (Ⅲ), and non-growing (Ⅳ), and nine sub-areas according to the condition of citrus freeze injury in winter and citrus dry damage in summer. Ecological conditions of area Ⅰ are basically suitable for mandarin growing.
