海藻提取物与锰肥配施对生菜生长的影响

The effects of seaweed extract with manganese application on the growth of lettuce

以生菜为材料,研究了海藻提取物与Mn肥配施对生菜生长的影响。结果表明,施用海藻提取物,可以显著提高生菜的茎粗、根长、株高、叶片数、干鲜重,并能促进茎叶对大量元素的吸收。而海藻提取物与Mn肥配施并不能进一步显著促进生菜生长,并且还抑制生菜茎叶对Mn元素的吸收。建议生产中海藻提取物不与Mn肥单独配合施用。

The effects of seaweed extract with manganese application on the growth of lettuce were investigated. The resuhs showed that stem and root width, root length, plant height, leaf number, fresh weight and dry weight increased significantly with the application of seaweed extract, and seaweed extract could promote shoot to uptake more nutrition elements. But seaweed extract with manganese application could not promote the growth of lettuce, and lower accumulation of manganese. Therefore, we suggest that seaweed extract was not used with manganese application.
