不同漂浮育苗基质对烤烟育苗的影响

为了解各种基质对烤烟育苗的出苗率、生育期和烟苗素质等的影响,采用铜仁基质、瑞安基质、金福基质、大兴基质和云南基质对烤烟进行育苗试验.结果表明,大兴基质出苗率最高,烟苗生长最快,苗期较其他基质短,烟苗叶片数、茎高、茎围、地上部干鲜重、地下部干鲜重等指标都较其他基质高,其次是铜仁基质.

Effect of Different Floating System Substrates on Tobacco Seedling

To understand effect of substrates on emergence rate,growth period and quality of the tobacco seedling breeding,an experiment was carried out by using of different substrates of Tongren,Rui'an Jinfu,Daxing and Yunnan.The result shows that the highest seedling emergence rate achieves by utilization of the Daxing substrate with the fastest growth,shorter seedling stage,more leaves,wider stem girth and higher stem height,dry/fresh weight aboveground part and underground part.The Tongren substrate is in the nex...
