| 摘 要： | 通过研究典型岩溶峰丛洼地常见饲料植物对矿质元素C a、M g、K、P、F e等的富集特征发现,岩溶峰丛洼地中元素在饲料植物各器官内的分布具有不均一性;大量元素C a、M g、K、P主要富集在饲料植物的叶片中,微量元素F e、有益元素N a主要富集在根部;饲料植物各器官对大量、有益元素的富集特征为高C a、K而低P、N a;生长于不同岩溶峰丛洼地区的同种饲料植物,由于岩溶地球化学背景及气候条件等的差异,其同类器官对同一元素富集的量不一样。

| Abstract: | By studying on the accumulating characteristics of elements Ca,Mg,K, P,Na,Zn,Fe and Cu in forage plants' organs in typical karst peak-cluster depressions,it is found that the distribution of elements in forage plants organs is uneven.Ca,Mg,K,P contents are higher in leaves than stems and roots,while trace element Fe and beneficial element Na mainly concentrate in roots.It is proved that elements Ca and K are enrichment in forage plant organs,while P and Na are rare.Due to the difference in karst geochemical background and climate condition etc.the same kinds of forage plants growing in different karst peak-cluster depressions accumulate the same elements differently. |
