苗床添加微生物菌肥对2种烟草种子发芽率和幼苗生长的影响
Effect of Microbial Fertilizer on Germination Rate and Seedling Growth of Tobacco in Seedbed
摘要
Abstract
To explore the application effect of microbe fertilizers on the flue-cured tobacco seedling ,this study was conducted to evaluate the effect of two bacterial manures, effective microorganisms (EM) and Bacillus mucilaginosus, with different treatments (5%, 10% and 15%) and their combination on the seed germination rate and seedling growth of'Honghuadajinyuan'and'Yunyan 85'. The results showed as follows:adding EM and Bacillus mucilaginosus in seedbed could improve the germination rate of the two kinds of tobacco seeds. The promoting effect of germination was mainly reflected in the post-germination stage (17-19 d after seeding) when adding one bacterial fertilizer. The promotion effect existed in the whole germination stage of'Honghuadajinyuan'when two bacterial fertilizers were applied as co-addition, while slightly inhibition was found on'Yunyan 85'in the initial germination stage, the germination rate was higher than that of the control at 21 d. The treatments of bacterial manures improved the growth of main root and lateral root of'Honghuadajinyuan'and'Yunyan 85'at three leaf period, the promotion of low concentration (5%) on the two kinds of tobacco seedlings was remarkable when adding EM only. While the promotion effect of middle concentration (10%) was notable when adding Bacillus mucilaginosus only. The agronomic characteristics could also be improved with the combination of two bacterial fertilizers in three leaf period. The application of EM and Bacillus mucilaginosus promoted the growth of root and the total number of root so as to modify the growth status at five leaf period. The plant height, stem diameter, longest leaf length and maximum leaf width of t he two kinds of tobacco seedlings were also improved with bacterial manures at 70 d after treated (before transplanting). To sum up, adding EM and Bacillus mucilaginosus in seedbed could improve germination rate and seedling growth of tobacco to different extent, especially adding 5%-10%.关键词
