钾肥对小麦Zn,Mn,Fe,Cu的吸收分配的影响
0
()
摘要:
在安微淮北地区棕壤白黄土上进行小麦不同施钾水平试验。结果表明:植株中Zn的浓度为叶片〉籽粒〉根〉茎;Fe的浓度为极〉叶〉茎〉茎粒;Mn,Cu浓度为根〉叶〉籽粒〉。小麦植株各器官的Zn浓度及根、叶中的Fe、Mn浓度与钾水平呈极显著曲线相关,但Cu浓度与钾水平相关不显著。

The Effects of K Supplement on the Absorption and Distribution of Zn,Mn,Fe,and Cu in Wheat
()
Abstract:
Different amount of K was supplemented to the soil of K deficient area of Huai Bei.Theresults showed that the distribution of Zn in plant is leaf>seed>roof>stem,while that of Feand Mn, Cu were root>leaf>stem>seed and root>leaf>seed>stem , respectively. There aresignificabbbnt curilineal correltionships between supplying K and Zn in each organ) Fe ,Mn (inroot and leaf),but no significant correlationship between supplying K and Cu.Whcn 14Kg/muK was supplied, the concentration as well as accumulation of zn,Mn,Fe ,and Cu in the plantwere the highest. At the period between the reviving stage and sprouting stage ,wheat plantconsames half of its absorbable total amount for Zn,Mn,Fe and Cu.
