摘要
以5～8年生米良1号猕猴桃雌株为试材,连续2年对其营养期根、茎、叶、果中主要矿质元素Ca、Mg、K、Zn、Mn、Na、Cu等的分配、吸收特性进行了研究。结果表明,米良1号猕猴桃叶片中的钙含量处于正常范围的下限,虽然根中的钙含量较高,而果实中的钙含量却一直维持在较低的水平;果实对钾的吸收则刚好与钙相反,果实中的钾含量列根、茎、叶之首;镁和锰在各器官中的分布及变化相似,叶中含量最高且都处于适量范围,其他部位含量变化不大;锌和钠除根中的含量在个别月份稍高外,其他部位的锌、钠含量在营养期几乎没有变化;根、茎、叶、果中铜的含量在4～9月间呈S曲线变化。
The distribution and absorption property of main mineral elements in various parts of Actinidia deliciosa cv. Miliang-1 in the vegetative period were studied. The results showed that the absorbing capacity of Ca, Mg, Mn, Zn by the fruit was quite low. The amount of Ca in fruit was only 1/4 of that of leaf and root, and the content of Mg and Mn in leaf were 5 to7 times more than that of fruit. Meanwhile, fruit had the maximal absorbing capacity of K in the vegetative period.
