| 摘 要： | 以酥梨为材料,研究了其整个生育周期营养器官中矿质元素的动态变化,结果表明,叶片内N,P,K,Cu的含量随叶龄的增加而降低,Ca,Mg,Mn的含量均随叶龄增加而升高;枝条中N,Ca的含量在整个生育期呈下降趋势,P,K含量先降低后有所回升,Mg,Mn含量逐渐上升,Cu含量变化较大;果实中N,P,K,Ca,Mg,Mn,Cu含量均随果实膨大而减少。

| Abstract: | The mineral elements in organs of Suli pear had been measured throughout the seasons.The results showed that the content of N,P,K,Cu in the leaves decreased with the increase of leaf age,while the content of Ca,Mg,Mn increased with the increase of leaf age.The content of N,Ca in the shoots reduced over the whole growth period,and the content of P,K decreased first and increased later.While the content of Mg and Mn increased gradually,the content of Cu changed largely and all the content of N,P,Ca,Mg,Mn,Cu i... |
