摘    要:为研究广东省茂名市小良水土保持试验推广站桉树的化学成分,测定了小良5种桉树的8种营养元素的含量。结果表明:同一品种桉树同一器官中各营养元素含量比较,4种大量营养元素含量总体表现为K〉Ca〉Mg〉P,4种微量营养元素含量绝大部分植物以Mn含量最高,Cu含量最低;4种大量元素P、K、Ca、Mg含量都表现为叶最大,枝次之,根和干中的含量较小;而4种微量元素Cu、Fe、Mn、Zn在植物各器官含量的高低排序缺乏一致规律;不同种桉树间的营养元素含量差别总体上缺乏一致规律。

关 键 词:茂名小良  桉树  营养元素

Abstract:To study the chemical composition of eucalyptus from Xiaoliang station of water and soil conservation,Maoming,8 nutrient elements from 5 eucalyptus were determined,among which,K,Ca,Mg,Cu,Fe,Mn and Zn were determined by flame atomic absorption spectrometry,P by ammonium molybdate spectrometry.The results showed that the contents of four macronutrients including P,K,Ca and Mg present K>Ca>Mg>P in the same organs of the same species.Among the four micronutrients,the content of Mn is the highest and Cu is the l...
Keywords:Xiaoliang Maoming  eucalyptus  nutrient element
