英文摘要: The effect of different concentrations of humic acid solution on the seed germination and early growth of tobacco seedling was studied. The results showed that the germination rate and germination potential of tobacco seed treated with algal humic acid solution increased by 0.1% - 0.2%. After treatment, the activity of seed peroxidase and catalase increased compared to that of the control. Among them, 0.05% - 0.2% of algal humic acid solution had better treatment effect. The results also showed that the chlorophyll content of tobacco leaves increased with different concentrations of algal humic acid solution, and the chlorophyll content was the highest in the concentration of humic acid which was 0.1%. The growth of tobacco seedlings can be promoted by the irrigation of 0.05% - 0.4%...
中文摘要: 用不同浓度腐植酸溶液对烟草种子进行浸种处理,研究其对烟草种子萌发的影响;同时研究不同浓度腐植酸溶液灌根对烟草苗期生长的影响。结果表明,用0.1%~0.2%的腐植酸溶液浸种可以提高烟草种子的发芽率和发芽势。处理后的种子过氧化物酶和过氧化氢酶的活性跟对照相比均有提高,其中0.05%~0.2%的腐植酸溶液处理效果较好。苗期灌根试验结果表明,不同浓度腐植酸溶液灌根对烟草叶片叶绿素含量均有提升作用,腐植酸浓度在0.1%时,叶绿素含量最高。0.05%~0.4%浓度的腐植酸溶液灌根可以促进烟草幼苗生长,增加株高和根长,有利于提高烟草幼苗生物量。
