| 摘 要： | 以0.5mmol/L NaHCO3分别和0mmol/L,0.5mmol/L,1.0mmol/L,1.5mmol/L的NaHSO3组合叶面喷施叶菜类植物叶用莴苣.结果表明,0.5mmol/L NaHCO3和0.5mmol/L NaHSO3组合对叶用莴苣有明显的增产作用,增产幅度较对照和单独喷施0.5mmol/L NaHCO3分别上升28.72%和17.70%左右;0.5mmol/L NaHCO3分别和0.5mmol/L,1.0mmol/L NaHSO3组合可明显增加株高和叶片数目,并显著提高植株的生长速率以及干物质的积累量;0.5mmol/LNaHCO3和不同浓度的NaHSO3组合可显著降低叶用莴苣的根冠比,促使干物质向经济器官的转运,提高经济产量.由此可见,将适当浓度的NaHCO3和NaHSO3有效配伍,可以作为一种良好的叶面肥进行尝试.

| Abstract: | NaHCO3 combined with NaHSO3 with different concentrations were applied on leaves of leaf-used lettuce respectively.The results demonstrated that 0.5mmol/L NaHCO3 0.5mmol/L NaHSO3 significantly increased yield of leaf-used lettuce by 28.72% and 17.70% respectively,compared to the control and 0.5mmol/L NaHCO3 application.0.5mmol/L NaHCO3 combined with 0.5 and 1.0 mmol/L NaHSO3 increased aboveground plant height and number of leaves,and significantly accelerated growth rate and accumulation of dry matters.0.5mmol/L NaHCO3 combined with 0.5,1.0 and 1.5 mmol/L NaHSO3 apparently decreased the ratio of root to leaf and enhanced day matter transportation to economic organs.It is reasonable to propose that proper combination of NaHCO3 and NaHSO3 can be used as leaf surface fertilizer to extend. |
