烤烟集约化育苗对烟苗素质的影响初探

An Primal Exploration on Influence of Intensive Seedling of Flue-cured Tobacco on Seedling Quality

在温室内采用漂浮育苗和托盘育苗两种方式育出的烟苗 ,表现为生长前期慢 ,中后期加快 ,比常规直播土体育苗的烟苗根系发达 ,冠根比较低 ,烟苗健壮 。

Seedlings produced by two intensive seedling methods (float seedling and tray seedling in the same greenhouse) show that seedling growth appears to be slow during early stage and faster during mid late stage. Their root system is very developed, the ratio between root and crown is lower, the seedlings are stronger and they have much better quality than seedlings produced by normal system.
