摘要: 通过对传统育苗盘进行改造,研究新型育苗方式对烟苗生长发育及生理特性的影响。结果显示,新型育苗方式在烟苗移栽前14 d进行多次断水炼苗,所育烟苗的壮苗率提高了10.6个百分点,根尖数增加了61.36%,烟苗的农艺性状有较大提高,其中茎粗、根鲜重和干重分别增加了45%、144%和150%,烟苗的缓苗期缩短了3.1 d,补苗量降低10.4个百分点;同时,烤烟的经济性状增加显著,产量、产值、均价、中上等烟比例分别提高了24.0%、38.4%、15.0%和15个百分点。

Abstract: The experiment was conducted to study the effects of new seedling raising methods on the growth and physiological characteristics of tobacco seedlings by reforming the traditional seedling plate. The results showed that the new seedling cultivation method increased the seedling rate by 10.6 percentage points, the number of root tips by 61.36%, and the agronomic characters of tobacco seedlings were greatly improved. The stem diameter, fresh root weight and dry weight increased by 45%, 144% and 150%, respectively. The seedling return time was shortened by 3.1 days. Supplementary seedling quantity reduced 10.4 percentage points. At the same time, the economic characters of flue-cured tobacco increased significantly, the yield, output value, average price and the proportion of middle-grade tobacco increased by 24.0%, 38.4%, 15.0% and 15 percentage points,respectively.

Key words: new seedling tray, root system, agronomic traits, seedling rate
