摘要:
为深入了解微生物菌剂在烟草育苗期的作用,探究其对烟草幼苗根系生长发育和烤后烟叶品质的影响,在烟草育苗时期,向漂浮育苗营养液中分别添加3种微生物菌剂:侧孢芽孢杆菌、枯草芽孢杆菌和地衣芽孢杆菌,研究微生物菌剂对烟草幼苗农艺性状、根系活力、抗氧化酶相关指标以及烤后烟叶化学成分的影响。结果表明,使用微生物菌剂对烤烟农艺性状、根系活力、抗氧化酶相关指标和烤后烟叶化学成分均有影响。随着烟苗的生长,3种微生物菌剂处理中,添加侧孢芽孢杆菌较对照显著提高了烟苗的根鲜重、根长度、根表面积、根体积及SOD、POD 和CAT活性,显著增强了根系活力,增加了可溶性蛋白含量,降低了MDA含量,烤后烟叶化学成分更加协调。因此,在实际生产中,推荐在烟草漂浮育苗营养液中添加侧胞芽孢杆菌促进烟苗根系发育,培育壮苗,提升烟叶品质。
