一、安徽气候及柑桔栽培简况安徽属于暖温带向亚热带过渡的地带,淮河以北属暖温带半湿润季风气候,淮河以南属亚热带湿润季风气候。由于全省地处东经114°54′～119°37′,北纬29°41′～34°38′,在冬季受蒙古高压和阿留申低压的控制和影响,常有北方干冷空气的侵袭,天气寒冷,对柑桔类果树有一定的威胁。我省长江的西部,如安庆、望江等地,多年平均极端最低气温不到-7℃。沿江和皖南南部地专气温较高,一般年平均气温16℃,宿松、望江可达16.6℃,1月平均气温在3.7～4.0℃之间,由南向北递增。
I. Brief Introduction of Anhui Climate and Citrus Cultivation Anhui belongs to the transitional zone from warm temperate zone to subtropical zone. It belongs to warm temperate semi-humid monsoon climate in the north of Huaihe River and subtropical humid monsoon climate in south of Huaihe River. Since the province is located between 114 ° 54 ’and 119 ° 37’ E and latitude 29 ° 41 ’to 34 ° 38’ E under the control and influence of the Mongolian and Aleutian low pressures in the winter, the northern part is often hit by dry and cold air and the weather Cold, citrus fruit trees have a certain threat. The western part of the Yangtze River in our province, such as Anqing, Wangjiang and other places, the average annual minimum temperature is less than -7 ℃. Temperatures in the special stations along the Yangtze River and southern Anhui are relatively high, with annual average temperatures of 16 ℃, and those of Susong and Wangjiang up to 16.6 ℃. The average temperature in January is between 3.7 and 4.0 ℃, increasing from south to north.
