为了明确南雄烟区生态特征，收集了南雄烟区近25年有兲气象资料，测定了南雄烟叶主产区300份土壤样品，系统分析了大田期气象条件及主要植烟土壤养分状况。结果表明，南雄烟区还苗期、伸根期气温偏低，降雨量偏多，日照时数偏少；旺长期气温、降雨量和日照时数较适宜；成熟期气温稍偏高，降雨量明显偏多，日照时数较长。紫色土偏碱性，有机质、氮含量较低，磷、钾含量较高；牛肝土田偏酸性，有机质、氮、磷、钾含量均较高；沙泥田呈酸性，有机质、氮、磷含量较高，钾含量偏低。3种植烟土壤类型水溶性氯含量普遍偏低，有效硼、交换性锰和交换性镁含量均处于极缺乏的水平。南雄烟区生态条件总体较适宜，但也存在一定的限制性因子。

In order to define the ecological characteristics of Nanxiong tobacco-growing areas,the meteorological data for 25 years inNanxiong tobacco-growing areas werecollected,and300ofsoil samples from major tobacco-planting areas in Nanxiong were collected,andthe meteorological conditions of tobacco field growing period and nutrient status of main tobacco planting soil were analyzed. The results showed that,during root spreading stage,temperaturewas too low,andprecipitationwas too high,and sunshine hourswas too lowin Nanxiong tobacco-growing areas.The temperature,rainfall and sunshine hourswere fineduring fast growing period, but these wereexcessive during maturing stage. The purple soil was alkaline,with loworganic matter and nitrogencontents and highphosphorus and potassiumcontents.The purple paddy soil was slightly acidic,with highorganic matter, nitrogen, phosphorus,andpotassiumcontents.The sand soil was acidic,with highorganic matter, nitrogen and phosphorusandlowpotassium andwater soluble chloridecontents. The contents of available boron, exchangeable manganese and exchangeable magnesium were extremely deficient in 3 soils. The ecological conditions of Nanxiong tobacco-growing areas ingeneralaresuitable,althoughthere are some limiting factors.
