不同菇渣营养土配方对烟苗及烟叶质量的影响

Effects of Different Mushroom Residue Nutrient Soil Formula on Quality of Flue-cured Tobacco and Tobacco Seedings

为了研究不同菇渣营养土配方在烤烟水旱两段式育苗的方式下对烟苗和烟叶质量的影响,以K326烤烟为试验材料,考察了不同菇渣营养土配方对假植烟苗成活率、生物量和烟株农艺性状、经济性状的影响。结果表明,水旱两段式育苗可提高成苗期烟苗生物量,缩短移栽后烟苗缓苗时间,提高大田长势整齐度、烤后烟叶质量和经济性状。50%菇渣+48%地表土+2%提苗肥与当地常规处理40%火土灰+60%地表土+提苗肥45.45 g/盘均对烟苗和烟株生长的影响优于其他处理,且差异不显著,可相互代替。

In order to study the effects of mushroom residue nutrient soil formula on the quality of the flue-cured tobacco and tobacco seedings, taking K326 as test material, effects of mushroom residue nutrient soil formula on survival rate, biomass, agronomic characters and economic characters of tobacco seedlings were measured.The results showed that the seedling through floating seeding and tray heel-in could increase biomass of the seedling, shorten the time of survival seeding after transplanting, enhance the field uniformity degree, raise economic characteristic. The effects of 50% mushroom residue＋48% topsoil＋2% hole applied fertilizer and local normal processing live 40% ash soil＋60% topsoil＋45.45 g per seedling tray on growning of the flue-cured tobacco and tobacco seedings were better than the other treatments,but the difference is not significant,so they can substitute for each other.
