一、广东柑桔生产分布概况广东省大部分地区处于北回归线以南,热量丰富、雨量充足,且雨热同期,年平均气温多在20℃以上,日平均气温≥10℃的活动积温达6000—9000℃,只有北部和西北部部分地区冬季有短期霜冻,年平均雨量多在1400毫米以上,很适合柑桔生长结果,是发展柑桔生产生态条件最优越的地区之一。广东省各地均有柑桔生产,90％柑桔生产分布在年平均温21—23℃等温线之间的地带。产量最多的是汕头市、广州市和惠阳地
First, the distribution of citrus in Guangdong Overview Guangdong Province in most parts of the Tropic of Cancer in the south, rich in heat, adequate rainfall, rain and heat over the same period, the annual average temperature more than 20 ℃, the daily average temperature of ≥ 10 ℃ activity temperature up to 6000 -9000 ℃, only the northern and northwestern parts of winter short-term frost, the average annual rainfall of more than 1400 mm, it is suitable for citrus growth results, is the development of citrus production and ecological conditions one of the most superior. Citrus production in all parts of Guangdong Province, 90% of the citrus production is distributed in the zone between the annual average temperature of 21-23 ℃ isotherm. The largest output is Shantou City, Guangzhou and Huiyang
