使用原子吸收光谱法对隘口村39个农业土壤样品有效态营养元素铜、锌、锰、铁、镁、钙的含量进行了测定,针对该地区农业土壤中有效态营养元素含量的多少进行了探讨。结果表明,隘口村石灰性褐土、黑土、沙壤土土壤类型中有效态锌和铜含量丰富,均属高等级水平;有效态锰、镁和钙含量中等,均属中等级水平;有效态铁含量严重缺乏,均属极低等级水平。红黏土类土壤中,有效态锰、镁和钙含量较低,属低等级水平;有效态锌、铜含量严重缺乏,属极低等级水平。
The contents of available nutrients Cu, Zn, Mn, Fe, Mg and Ca in 39 agricultural soils in Weiguo Village were determined by atomic absorption spectrometry. The content of available nutrients in agricultural soils in this area was discussed . The results showed that the contents of available zinc and copper in the calcareous cinnamon soil, black soil and sandy loam soil of Weiguokou Village were all high, and the contents of available manganese, magnesium and calcium were middle level. The effective iron content A serious lack of low-grade level. Red clay soil, the effective content of manganese, magnesium and calcium is low, is a low level; the effective state of zinc, a serious lack of copper, is an extremely low level.
