摘 要:为探讨偏高肥力烟田土壤宜烟性改良,研究了冬闲期种植‘冬牧70’,全部翻压掩青和地上部收割移出烟田2种处理方式对土壤改良和烟叶产质量影响。结果表明,偏高肥力烟田冬闲期种植‘冬牧70’,随地上部收割88 kg/hm^(2)氮被移出烟田。‘冬牧70’翻压掩青和收割均能提高0~20 cm土层土壤有机质含量,同时显著增加了土壤脲酶、转化酶及碱性磷酸酶活性。‘冬牧70’收割处理降低了烟叶氮吸收积累量,促进了烟叶成熟落黄。‘冬牧70’收割处理烟叶化学成分协调性好于掩青处理,烟叶产值较掩青处理提高8.5%。烟田土壤肥力偏高情况下,冬闲期种植‘冬牧70’并收割地上部移出烟田,可以明显提高烟叶产质量。To explore the improvement of tobacco suitability in tobacco field with high fertility,the effects of two treatments(ploughing green-manure and overground harvest)of planting secal ecerale‘Dongmu 70’in winter period on soil improvement and yield and quality of flue-cured tobacco were studied.The results showed that 88 kg/hm^(2) nitrogen could be brought out of the tobacco fields with overground harvest of‘Dongmu 70’.The soil organic matter content in 0-20 cm soil layer was increased by both ploughing green-manure and overground harvest,and the activities of urease,invertase and alkaline phosphatase were also increased significantly.The overground harvest reduced the nitrogen accumulation and promoted the maturation of fluecured tobacco leaves.Harmony of chemical composition of flue-cured tobacco leaves of overground harvest treatment was better than that of ploughing green-manure,and the economic values increased by 8.5%.So in high fertility tobacco field,planting‘Dongmu 70’in winter period with overground harvest treatment could obviously improve the yield and quality of tobacco leaf.
