烤烟二段式漂浮育苗炼苗方式研究

Study on Flue-cured Tobacco Two Section Type Floating System

[目的]解决烤烟二段式漂浮育苗移栽成活率低、移栽成本高等难题,实现种烟"减工降本、提质增效"目的。[方法]采用对比调查分析法,比较常规揭膜法炼苗与断水揭膜法炼苗的炼苗成本、烟苗根系生长情况、移栽成活率及移栽成本。[结果]采用断水揭膜方法炼苗能促进烟苗根系生长,增强烟苗移栽抗旱能力,提高烟苗移栽成活率,减少移栽成本。[结论]断水揭膜法炼苗适合推广应用。

[Objective] To solve the issue of low survival rate and high cost of flue-cured tobacco two section type floating system transplanting.[Method] Using contrast investigation method,seeding cost,tobacco roots growth situation,transplanting survival rate and cost of conventional film uncovering method and water-break film uncovering seeding method were compared.[Result] Using water-break film uncovering seeding method can promote tobacco roots growth,strengthen tobacco seedling transplanting drought-resistance ability,improve survival rate and reduce transplanting cost.[Conclusion]The water-break film uncovering seeding method is appropriate for extension and application.
