油茶苗期不同器官对各营养元素的吸收及养分间分配规律

Regularity of nutrient absorption and distribution in different organs of Camellia oleifera at seedling stage

为了弄清油茶苗期不同器官对营养元素的吸收分配规律,对150株油茶苗期不同器官的营养元素含量进行了测定,分析了各营养元素之间分配的相关性。结果表明:N含量最高,K和Ca含量次之,Cu和B含量最低;油茶苗期叶片中主要营养元素N、P和K的吸收分配存在相互影响与相互促进的关系,而其根与茎中N、P和K的吸附分配没有显著的相关性。苗期的油茶对各营养元素的吸收分配存在明显的规律性,可以针对营养吸收分配规律开发新型油茶苗期专用肥。

In order to study nutrient absorption and distribution regularity in different organs of Camellia oleifera at seedling stage, the nutrient contents in 150 seedlings were determined and the correlation of distribution between different elements was analyzed. The results show that the N content is the highest, followed by K and Ca contents, Cu and B contents are the lowest. Absorption and distribution of N, P and K in leaves exists the relationship of mutual influence and promotion at seedling stage, but that in roots and stems has no significant correlation. Absorption and distribution of the nutrients exists an obvious regularity at seedling stage, so the new special fertilizer for C. oleifera at seedling stage can be developed based the regularity.
