移栽时间与方式对烤烟生长及产质量的影响

为探明移栽期和移栽方式对烤烟生长发育及产质量的影响,得出最佳的移栽期与移栽方式配套技术应用于生产,以云烟87为材料,进行不同移栽期与移栽方式二因素裂区试验。结果表明:吉安烟区膜下小苗移栽处理烟株前期生长发育快,井窖式移栽处理后期生长发育较快,大田生育期缩短;移栽过早或过晚,烟株生长发育及经济性状均较差;江西吉安的烟叶生产以常规移栽期加井窖式移栽的经济性状及品质最好。

Effects of Transplanting Time and Models on Growth,Yield and Quality of Flue-cured Tobacco

In order to explore the effects of transplanting periods and models on growth, development, yield and quality of flue-cured tobacco, thus to find out the best matched technology of transplanting periods and models.Flue-cured tobacco variety Yunyan 87 was taken as research materials and a two factors split plot experiment was designed.Results: Under-film young seedling transplanting treatment was of the faster growth and development of tobacco plants in early stage.Tobacco plants of well-cellar transplanting treatment grew faster in late period, and the field growth period was shortened;Either early or later transplanting resulted in worse growth, development and economic traits of tobacco plants;The best economic characters and quality of the tobacco leaf production in Ji'an Jiang xi were treated by Well-cellar transplanting in the conventional transplanting period.
