一年生落叶松苗体内8种元素积累与分配的动态变化

The Pattern of Accumulation and Distribution of the Eight Elements in One-Year-old Seedling of Larch

本文报道了一年生落叶松苗体内Ｃａ、Ｍｇ、Ｎａ、Ｃｕ、Ｆｅ、Ｚｎ、Ｍｎ、Ｍｏ等８种元素定位观测结果。在明一年生落叶松苗对８种元素的吸收、积累与分配，因生长期不同而呈现规律性变化。上述８种元素在一年生落叶松苗体内的分布各有其不同的特点。为阐明一年生落叶松苗体内元素的营养状况，合理施用微肥提供了理论依据。

The results showed that the absorption,accmulation and distribution of the eight elements in one-year-old seedling vary regularily in different growth Periods.The distribution of the eight elements in one-year-old larch presents their own characters respectively.The study provides theoretical basis for the element nutrient state and reasonable administration of trace fertilizers.
