烤烟催芽包衣种子试验

Experiment on Pelleted Germinating Seeds of Flue-cured Tobacco

  • 摘要: 为了提高包衣种子的发芽率和出苗整齐度,进行了烤烟催芽包衣种子的试验。结果表明,催芽包衣种子较常规包衣种子的发芽势提高了21.7~35.8个百分点、发芽率提高了3.2~9.2个百分点。在大理州烟区催芽包衣种子可提前出苗5~7d,苗期与大田期烟株的生长势和生长整齐度均优于常规包衣种子。

     

    Abstract: For improving the germination percentage and uniformity of seedlings, the pelleted germinating seeds of flue cured tobacco were experimented. The results showed that the germinating viability and germination percentage of pelleted germinating seeds were increased by 21.7-35.8 and 3.2-9.2 percentage points than that of normal pelleted seeds, respectively. The seedling emergence time of pelleted germinating seeds was 5-7days ahead of normal pelleted seeds in Dali tobacco growing areas, and the growth vigor and uniformity of seedlings in beds and fields were better than those of normal pelleted seeds.
