通过外界电场刺激烟草种子９０～１２０ｍｉｎ后，烟草种子的萌发率和萌发势明显得到提高。烟苗的假植和大田移植成苗率也得到提高。经过外界电场刺激的烟草种子在同一生长时间内，烟苗的地上部和根系的生长量增大，所培育的烟苗整齐键壮。特别是对两年以上的烟草种子外界电场所产生的刺激效果更为明显。 After 90 ~ 120min stimulation of tobacco seeds with external electric field, the germination rate and germination potential of tobacco seeds obviously increased. Seedlings of fake plants and field transplant seedling rate has also been improved. After the external electric field stimulated tobacco seeds in the same growth time, the growth of tobacco shoots aboveground and root growth, the nursery tobacco neat and tonic. In particular, more than two years of tobacco seeds outside the electric field generated by the stimulus effect is more obvious.
