对新疆阿勒泰市土山罗布麻保护区的5个不同居群的罗布白麻(Poacynum hendersonii)叶片中的N、P、K、Na、Ca、Mg、Cu、Fe、Zn和Mn 10种营养元素含量进行了测定和比较。结果表明,青杆中花麻为N-Ca类型、特细叶中花麻和红杆中花麻为N-K类型,N含量在特细叶中花麻中显著高于其他4个居群(P<0.05);中细叶中花麻为K-Ca类型、白花中花麻为K-N类型,其K含量显著高于其他3个居群。5个居群罗布麻叶片中4种微量元素的含量,除红杆中花麻居群中Mn含量最高外,其余4个居群均为Fe>Mn>Zn>Cu;各居群Fe和Zn含量无显著差异;各居群间Mn含量差异显著;青杆中花麻、红杆中花麻和特细叶中花麻Cu含量显著高于中细叶中花麻,白花中花麻与各居群间均无显著差异。相关分析表明,罗布白麻居群中Mg与Mn,K与P,Ca与Mg,Fe与Zn含量呈显著正相关性;而Na与Ca,K与Cu和Mn,P与Cu和N含量呈显著负相关(P<0.05)。
The contents of N, P, K, Na, Ca, Mg, Cu, Fe, Zn and Mn in five different populations of Poacynum hendersonii in the Tushan apocynum protected area in Altay, Measured and compared. The results showed that the flowers of Maize were N-Ca type, the flowers of Maize and Maize were NK type, the content of N was significantly higher than that of the other four populations (P <0.05). In the middle and fine leaves, the flower Ma was K-Ca type, the flower Ma was Ma and the K content was significantly higher than the other three populations. The contents of four trace elements in five populations of Apocynum venetum leaves were the highest among all the four populations, except that the content of Mn was the highest in the population. There was no significant difference in the content of Mn among different populations. The content of Cu in Maize Matrine, Matrichillae heterotrophicum, There was no significant difference between populations. Correlation analysis showed that the contents of Mg and Mn, K and P, Ca and Mg, Fe and Zn were significantly and positively correlated with the Roberts hemp populations, while the contents of Na and Ca, K and Cu and Mn, P and Cu and N were significantly Significant negative correlation (P <0.05).
