采用烟草专用复合肥配制纯氮浓度为100 mg·kg-1、200 mg·kg-1、300 mg·kg-1的营养液,与漂浮育苗专用营养液进行对比试验。结果表明,用专用复合肥配制纯氮浓度为200 mg·kg-1、300 mg·kg-1的营养液与专用营养液相比可以促进烟苗的生长,烟苗株高、叶数、茎鲜重、茎干重以及根系重量和体积均较专用营养液明显增加,其中部分指标差异达到显著性水平。表明采用烟草专用复合肥配制的营养液可以替代漂浮育苗专用营养液。
The special compound fertilizer for tobacco was used to prepare the nutrient solution with pure nitrogen concentration of 100 mg · kg-1, 200 mg · kg-1, 300 mg · kg-1, and compared with the special floating nutrient solution. The results showed that the use of special compound fertilizer formulated pure nitrogen concentration of 200 mg · kg-1, 300 mg · kg-1 nutrient solution compared with the special nutrient solution can promote the growth of tobacco seedlings, tobacco plant height, leaf number, stem The fresh weight, the stem weight and root weight and volume were significantly higher than that of the special nutrient solution, and some of the indexes reached the significant level. Show that the use of tobacco-specific compound formulated nutrient solution can replace floating nursery nutrient solution.
