摘要
本文研究了湖州地区水稻土、红壤和潮土三种主要土壤类型的土壤微量元素Fe、Mn、Cu、Zn、B、和Mo的有效态含量,并对各微量元素的有效态含量满足作物生长需要的状况进行评价。结果表明:湖州市土壤大面积缺钼,部分土壤缺锰、硼,而土壤有效态铜、锌含量比较丰富,土壤有效铁含量则极其丰富。最后对该市水稻土、红壤和潮土三种主要土壤类型的土壤微量元素含量与成土母质、pH、土壤有机碳之间的关系进行分析研究。
The available contents of Fe, Mn, Cu, Zn, B and Mo in paddy soil, red soil and fluvo-aquic soil, the three main soils in Huzhou City of Zhejiang province were studied, and the availability of the trace elements were evaluated in this paper. The results showed that Mo was deficient in large areas, While B and Mn were insufficient in some soils, however, the contents of available Cu and Zn were high, and the content of available Fe was also high. Meanwhile, the correlations among the available contents of the different trace elements and the soil parent materials, soil pH and soil organic matter in the three main soils were also discussed.
