摘要
应用叶分析技术对平榛矿质营养年周期变化规律进行了研究。结果表明:随着物候期的进展,平榛叶片内各种矿质元素的含量有规律变化。但是,不同元素间变化规律有所差异,在结果枝和发育枝的叶片中变化规律基本相同。初步确定了平榛叶分析营养诊断的采样适期和采样部位。
A study on the annual variation of mineral nutrient element contents in the leaves of Siberian Filbert was carried out by leaf-analysis method. The result showed that the content of each element in Siberian Filbert leaves had a regular change as its phenological periods advanced. However, the rhythms of change among the various elements were different. The rhythms of change between the leaves of the vegetative and fruit shoots were almost the same. The suitable pe riod and location of sampling for leaf analysis diagnosis of Siberian Filbert were determined.
