摘要
采用调查采样、室内分析和评价的方法,研究了湖南省几种主要母质发育的水稻土的有效态微量元素含量及丰缺状况。结果表明,土壤有效Fe和有效Mn含量很高,属于丰富级别;土壤有效Cu、有效Zn和有效B含量极低,处于缺素状态,需要补充和施用Cu、Zn和B肥,以保证水稻的正常生长。
The contents and degree of abundance and defliciency of available Fe, Mn, Cu, Zn and B in the paddy soils derived from several main parent materials were studied through investigating and sampling, indoor analyzing and evaluating methods in Hunan province, The results showed the contents of the soil available Fe and Mn were very great, belonged to degree of very abun- dance, while that of the available Cu, Zn and B terribly low, in degree of insufficiency. It was essential that the fertilizer of Cu, Zn and B was apphed in order to ensure the rice growth in paddy soil of Hunan province.
