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、增强仁用杏抗逆性提供依据
The contents of copper and zinc in root, trunk, branches and leaves of Apricot benevarius during different growth stages were analyzed by atomic absorption spectrophotometry. The results showed that the content of copper and zinc was related to the growth of apricot, and was an essential nutrient element of the tree. The relationship between copper and zinc and the apricot cold resistance had a certain relationship. In this study, Enhance apricot stress resistance provide the basis
