Analysis onEcological Conditions in Nanxiong Tobacco-growing Areas
摘要
Abstract
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.关键词
