| 中文摘要: |
| 文章对浙江省吴兴区耕地进行土壤养分地球化学特征分析,为吴兴区耕地合理利用及有效治理提供科学依据。通过对1960个样品进行pH、有机质、氮、磷、钾、硼、钼元素含量分析测试,发现湖州市吴兴区耕地土壤酸碱度以酸性为主,有机质含量处于中等偏高状态,氮和钼元素平均值高于浙江省平均值,硼元素平均值低于浙江省平均值,其中氮含量中等偏富集,磷元素中等,钾、硼、钼元素富集。根据土壤养分综合等级划分,研究区耕地土壤养分丰富和较丰富地区占38.11%,适中地区占52.45%,缺乏及较缺乏地区占9.44%。 |
| 英文摘要: |
| This work analyzed the geochemical characteristics of cultivated soil nutrients in the Wuxing District of Zhejiang Province in order to provide scientific basis for the utilization and management of cultivated land in the Wuxing District. A total of 1960 collected samples were tested on their contents of pH, organic matter, nitrogen, phosphorus, potassium, boron and molybdenum. It is concluded that the acidity and alkalinity of cultivated land in the Wuxing District are mainly acidic, the content of organic matter is medium to high, the average content of nitrogen and molybdenum elements is higher than that of Zhejiang Province, and the average value of boron is lower than that of Zhejiang Province. Specifically, nitrogen is moderately enriched, phosphorus is moderately enriched, and potassium, boron and molybdenum are enriched. According to the comprehensive classification of soil nutrients, it is shown that 38.11% of the cultivated land in the study area is rich in soil nutrients, 52.45% is moderate, and 9.44% is deficient or relatively deficient in soil nutrients. |
