缺钾对生姜吸收铁锰铜锌的影响

试验结果表明:缺钾显著降低生姜吸收铁、铜、锌元素的能力,使生姜各器官的铁、铜、锌含量降低;但缺钾促进了生姜生长前期对锰元素的吸收,提高了锰在地上部的含量,但生长后期生姜体内锰元素流失较早且多,使单株生姜的锰吸收量反而低于正常供钾处理。

Effect of potassium deficiency on absorption of Fe, Mn, Cu and Zn in ginger

The effects of potassium (K) deficiency on the absorption and distribution of Fe, Mn, Cu and Zn in ginger were carried out in this experimentThe result showed that K deficiency weakened the roots ability of absorbing Fe, Cu and Zn, which reduced the content of Fe, Cu and Zn in different part of gingerWhile K deficiency enhanced the ability of absorbing Mn,which increased Mn content in leaves,but induced the Mn release from the roots to environment at later growth stage,and finally decreased the accumulation of Mn in individual plant in comparison with K supplied normally
