| 摘 要： | 根据杭嘉湖平原区区域地球化学调查的结果,对本区土壤中农作物营养元素含量及有效量特征进行了评价研究。研究结果表明,本区土壤中营养元素除Mo、S含量表现缺乏外,其它元素为足量和丰富水平。不同土壤中营养元素有效量水平存在明显差异。在区域分布规律上,营养元素的含量及有效量随成土母质、成土过程和人类耕作等因素的不同而显示其差异特征。评价研究结果为本区农业生产中的合理区划、科学施肥、合理种植、土壤改良等提供了重要的地球化学依据。

| Abstract: | Based on regional geochemical investigation performed in the Hangzhou-Jiaxing Huzhou plain, the authors made an evaluation on contents and effective quantity of nutlitive elements in soils of this area. The results indicate that in soils of this area, nutritive elementsare enough or abundant except Mo and S which are deficient, and that effective quantity levels of nutritive elements show notabole difference in different soils. In regional distribution regularity, the content and effective quantity of nutritive elements exhibit differential characteristics, depending on the differences in such factors as soil parent materials, aoil-forming process and farming. The results of this evalwtion have provided an important geochemical basis for rcasonable regionalization, scientific application of fertilizer, rational plantation and soil ilmpovement. |
