安徽省主要植烟土壤潮土、砂姜黑土、红壤质地均较粘重 ,潮土、砂姜黑土粘土矿物以蒙脱石为主 ,红壤粘土矿物以高岭石为主 ,有机质含量不高 ,潮土缺磷 ,砂姜黑土和红壤缺钾。重视施用有机肥和合理耕作来改良土壤物理特性。施肥上适量施氮肥 ,增施磷钾肥 ,重视微量元素的施用。潮土和砂姜黑土的施肥方法以基肥为主 ,追肥为辅 ;红壤要求基追肥相结合 ,基追肥的比例一般为 7∶3 ,追肥必须在烟叶移栽后 3 0d内施完 The main tobacco-growing soil in Chaoan, Anhui Province, Shajiang black soil, red soil texture are more viscous, clay, clay in Shacha black soil is dominated by montmorillonite, red clay clay minerals are mainly kaolinite, organic matter content is not high, Soil phosphorus deficiency, Shajiang black soil and red soil potassium deficiency. Emphasis on applying organic fertilizer and reasonable farming to improve soil physical characteristics. Fertilization on the amount of nitrogen fertilizer, increase phosphorus and potassium fertilizer, attention to the application of trace elements. Chao soil and sand Jiang black soil fertilization method based on basal fertilizer, topdressing supplemented; red soil base and top dressing required, the ratio of top dressing is generally 7: 3, top dressing must be applied within 30 days after transplanting tobacco leaves
