| 摘 要： | 对南泉、北碚地区一年四季黄连木叶片的营养状况和矿质元素进行测定分析,研究野生黄连木不同时期矿质元素的变化规律。结果表明:成年黄连木矿质元素变化总趋势为N、P、K下降,Fe、Ca上升,Mg、Zn则是波动变化。根据盆栽施肥试验的研究以及与成年树变化规律差异分析,可以推断不同土壤条件、不同树龄、不同栽培管理都会影响黄连木叶片矿质元素的含量变化,可以通过合理施肥,来补充黄连木树体N、P、K元素含量,保证N、P、K元素的充足供应,促进新梢生长发育、提高花芽分化的质量。

| Abstract: | The nutrition and mineral elements in leaves of Pistacia chinensis in area of Nanquan and Beibei were determined and analyzed,the different periods changes of mineral elements of the wild Pistacia chinensis all the year round were studied.The results showed that matures’ mineral elements generally changed trend that N,P,K decreased,Fe,Ca had generally increased,and Mg,Zn were fluctuation.According to the pot fertilization experiment researched as well as the variation difference analysis of matures,could be inferred that different soil conditions,different ages,different cultivation and management would affect the contents of mineral elements in leaves of Pistacia chinensis.Through reasonable fertilization to supply the Pistacia chinensis N,P,K elements,ensured N,P,K elements adequately,promoted new shoot growth,and improved the quality of flower bud differentiation. |
