宜春烟区土壤肥力状况评价

Evaluation of Soil Fertility in Yichun Tobacco-growing Area

为江西宜春烟区烤烟的合理施肥提供依据,进行了宜春烟区151个土壤样品的肥力测定分析。结果表明:宜春烟区土壤碱解氮、速效磷和有机质含量较高,分别为121.00 mg/kg、25.80 mg/kg和25.54g/kg;而速效钾含量在适宜范围的下限,为87.00mg/kg;土壤养分含量丰富,部分植烟土壤pH偏酸性。宜春烟区烤烟生产中应合理控制施氮量,补足钾肥及调节土壤pH。

151 soil samples were analyzed from the tobacco--planting region of Yichun to provide references for rational fertilization in Yichun tobacco-growing area in Jiangxi Province. Results： Available nitrogen, available phosphorus and organic matter were high, respectively 121.00 mg/kg, 25.80 mg/kg and 25.54 g/kg. While available potassium was at the lower limit of optimum range, merely 87.00 mg/kg; The soil nutrient content was rich and part of soils were acidity in Yinchun. It was suggested to control nitrogen fertilizer, enhance potassium fertilizer and also pH value should be adjusted in the production of flue-cured tobacco.
