| 摘 要： | 目的]探讨恩施州白肋烟大田期适宜气候条件。方法]对恩施烟草大田生长期间旬平均温度、平均降水量和光照与优质烟叶生长所需温度、降水和光照进行对比分析。结果]还苗期降水不足、成熟期降水偏多是制约优质烟叶生产的重要因素。提出相应生产措施:选择生育期稍长的中、晚熟品种;改善现有的育苗方式,增加烟苗的移栽弹性;移栽前施足底水;中后期加大培土,形成高垄深沟,排水降湿;同时加强病虫害防治等。结论]该研究对恩施州烟草区域分布、品种布局、生产技术的选择及防灾减灾有更具体的指导意义。

| Abstract: | Objective] The aim was to discuss the suitable climate conditions of burley tobacco in field period in Enshi.Method] The relationship between the average temperature,precipitation,light during the ten-day and the good tobacco physiological requirement were compared and analyzed.Result] The lack of precipitation at seedling stage and too much precipitation at mature stage were the important impedimental factors of the high quality tobacco production.The corresponding cultivation measures were summed up,which were as follows：selecting the mid-or-late-maturing varieties with long growth period; improving the existing way of seedling as to increase the flexibility of tobacco seedlings transplanting; irrigating water enough before transplanting; being taken the shape of high-ridge and deep-moat by earthing up at midand-late stage; enhancing the prevention and control of diseases and insect pests at the same time.Conclusion] The study had a better specific guidance significance for tobacco areal distribution,varieties allocating,choosing the production technology,and prevention and reduction of natural disasters in Enshi. |
