烟田不同土壤改良模式对烤烟产质量的影响

摘要

[目的]寻求与秦巴烟区自然和社会经济条件相适应的烟田土壤改良模式,以期保持最佳土壤条件.[方法]利用大田试验,2016年在陕西省陇县八渡镇研究了T1蚯蚓粪有机肥、T2烟秆有机肥、T3豆饼有机肥、T4生物炭有机肥不同土壤改良模式对烤烟生育期、农艺性状及经济性状的影响.[结果]T3、T4处理能提高烟叶产质量,增加烟农收益;T1、T2处理效果不明显.[结论]该研究为探寻最佳的土壤改良模式提供了依据.%[Objective] To explore the model of soil improvement in tobacco field,which is suitable for the natural and social economic conditions in Qin-Ba tobacco area.[Method] The effect of T1(wormcast organic fertilizer),T2(tobacco stem organic fertilizer),T3(bean cake organic fertilizer),T4 (biochar organic fertilizer) on flue-cured tobacco growth period,agronomic and economic traits in Badu Town, Longxian were studied by field experiment in 2016.[Result] T3 and T4 treatment could improve the quality of tobacco leaf production,increase farmers' income.The effects of T1 and T2 treatment were not obvious.[Conclusion] The study provides a basis for exploring the best model of soil improvement.
