沃益多生物菌肥对烤烟漂浮烟苗生长的影响

Effects of HYT Microbial Fertilizer on Growth of Tobacco Float Seedlings

［目的］为解决烤烟育苗前期普遍存在的光照不足、低温持续时间长而导致的育苗时间延长、烟苗素质不高、移栽偏晚等问题。［方法］施用不同浓度组合的“沃益多”（HYT）生物菌肥，设置常规对照，观察其对烟苗生长发育状况的影响。［结果］各处理烟苗株高、茎围、根长、烟苗鲜重、根系鲜重及根系活力均高于对照，且成苗时间比对照提早2~5 d，长势旺, 叶色绿，烟苗健壮。［结论］在漂浮育苗培育过程中添加HYT生物菌肥，能缩短烟苗生育期，促进烟苗的生长和根系的发育。

[ Objective] The research aimed to solve the problems such as nursery process prolonged, low quality tobacco seedlings so that transplanting delayed because of the lack of light, long-term low temperature during the earlier stage of tobacco float seedlings. [Method] Uti- lizing different concentration ＂WoYiDuo＂ （HYT） bio-fertilizer and confrol treatment, its effects on tobacco seedlings growth development were studied. [ Result J In contrast to the control, the plant height, stem circumference, root length, fresh weight and root activity of each treatment were higher and the seedling time was 2 - 5 days earlier and the tobacco seedlings had better growth that performed green leaf and robust. [ Conclusion] Adding HYT bio-fertilizer into the cultivation process of tobacco float seedlings could shorten the growth period and promote the growth and root development of tobacco seedlings.
