摘要
利用原子吸收分光光度法对仁用杏不同生育期的根、树干、枝和叶等器官的铜、锌含量进行了分析测定。结果表明 :铜和锌的含量与仁用杏的生长相关 ,是树体必需的营养元素 ;铜、锌与仁用杏的抗寒性有一定的关系 ;本研究为合理施用铜锌微肥。
By the atomic absorption spectrometry, the copper and zinc content of prunus'root, trunk, and leaves of different growth period is analyzed. It turns out that copper and zinc content is related to the prunus growth and is substantial to the body.Besides,to some degree, copper and zinc are bound to the cold-resistant property of the prunus. The paper supplies foundation for rational employing fertilizer containing copper and zinc.
