移栽方式对烤烟生长的影响及经济效益分析

Effect of Transplanting Methods on Tobacco Growth and the Economic Benefit Analysis

为了探索合适的烤烟移栽方式,研究了带营养土高茎深栽、穴窝深栽和常规移栽方式对烤烟根系发育、田间农艺性状以及经济效益的影响。结果表明,穴窝深栽可加快烟苗返苗,促进大田前期根系发育,有利于打顶后各项农艺性状指标的优化,降低青枯病的发病率,且节省移栽环节用工成本,提高烟叶产质量。穴窝深栽与带营养土高茎深栽和常规移栽比较,在移栽环节节省用工分别为1477.80和1115.20元/hm2,烤后产值分别增加963.90和1218.70元/hm2。穴窝深栽方式是邵武烟区最具经济效益的移栽方式,具有在闽西北烟区推广应用价值。

In order to identify the best transplanting approach for flue-cured tobacco, a field experiment was conducted with threeapproaches： high-stem deep-planting with nutrition soil mode （HSDP）; the deep-cave-planting （DCP）; and the normal planting （NP）.The results showed that the DCP could speed up the seedling to restitute after transplanting, promote the tobacco root system todevelop before the rosette stage, optimize the agronomical characters in field after topping, reduce the incidence of bacterial wilt andthe harm degree. DCP-mode could increase the yield and quality of tobacco leaves, save the labor cost in transplanting. DCP andHSDP used labor cost 1477.80 and 1115.20 Yuan/ha less than NP for transplanting, and output value was 963.90 and 1218.70Yuan/ha more than NP, respectively. The DCP was the most economic transplantation mode for Shaowu tobacco growing areas, andshould be recommended to the local and nearby tobacco growing areas of Fujian province.
