摘 要:为培育高素质烟苗,提高壮苗率,开展了基质添加和叶面喷施褐煤基调理剂及褐煤基悬浮液态肥替代常规育苗肥研究。结果表明,与对照相比,基质中添加适量的褐煤基调理剂(720 mL/m^(3)),可增加根长、根表面积、根干重、根/茎干重比,并提高根系活力,有利于培育壮苗;褐煤基悬浮液态肥替代常规育苗肥,虽然能明显刺激烟苗根系生长,但茎叶生长较弱,成苗时间延迟,还需在调整配方基础上开展进一步研究。In order to cultivate high-quality tobacco seedling and improve the rate of strong seedling,the addition of lignite-based conditioner to substrate,foliar spraying of lignite-based conditioner and lignite-based suspended liquid fertilizer replacing conventional seedling fertilizer were studied.The results showed adding lignite-based conditioner(720 ml/m^(3))into substrate could increase root length,root surface area,root dry weight,root/stem dry weight ratio,and root activity,which is conducive to the cultivation of strong seedlings.The new suspended liquid fertilizer completely replacing the conventional chemical fertilizer for seedling,although it could stimulate the root growth of tobacco seedling,but the growth of stem and leaf was weak and the time of seedling formation was delayed,further research is needed on the basis of adjusted formulation.
