不同催芽方式对烤烟成苗素质及育苗成本的影响

摘要

The effects of different accelerating germination modes on the seedling quality and seedling - rearing cost of flue -cured tobacco were studied in Qiandongnan state of Guizhou province. The results showed that; in comparison with the conventional seedling - rearing mode, the accelerating germination modes of heating air by furnace - tube and heating seedbed by electric wire could accelerate the emergence of seedlings, shorten the duration from sowing to transplanting, and enhance seedling -forming rate. As for seedling quality and seedling - rearing cost, the accelerating germination mode of heating seedbed by electric wire was better than that of heating air by furnace - tube.%在黔东南州研究了不同催芽方式对烤烟成苗素质及育苗成本的影响.结果表明:与常规育苗方式相比,炉管加热空气和电热丝加热苗床的催芽方式均可以提前烤烟的出苗时间和成苗时间,提高成苗率,其中电热丝加热苗床的方式在烟苗素质和育苗成本方面均优于炉管加热空气的方式.
