纳米碳溶胶对烤烟生长发育及养分吸收积累的影响
Tobacco Science and Technology(2013)
Abstract
为明确纳米碳溶胶对烤烟养分吸收利用的作用效果,采用水培试验研究了不同浓度纳米碳溶胶对两个烤烟品种红花大金元(红大)和K326生长发育及养分吸收积累的影响.结果表明,适宜浓度的纳米碳溶胶能够促进烤烟植株的生长发育,当溶胶浓度为10 mg/L时,烟株地上部生物量显著提高.纳米碳溶胶还能促进烤烟对氮、钾、钙、镁的吸收,增加其在地上部的含量.两个烤烟品种养分积累量均随纳米碳溶胶浓度的升高呈先增加后降低的趋势,当溶胶浓度分别为5~10 mg/L和10~20 mg/L时,红大和K326的养分积累量达到最大.可见,水培条件下,烟株生长状况达到最佳的最适纳米碳溶胶浓度红大品种为5 ~ 10 mg/L,K326品种为10~20 mg/L.
