| 中文摘要: |
| 为了探索安龙县耕地土壤有效态微量元素丰缺规律，文中对采集的数据采用平均值±3倍标准差法筛选后，对碱解氮、速效磷、速效钾、有效硼、有效钼、有效锌、阳离子交换量等7个有效态与对应点位全量元素含量特征值及转换率进行了统计和分析，并对全县及不同土地利用类型、成土母岩、土壤类型、乡镇等有效态微量元素丰缺程度进行了评价。为安龙县土地利用调整、规划用地、施肥等提供了参考依据。 |
| 英文摘要: |
| In order to explore the rule of soil available micronutrient Abundance and Deficiency in AnlongCounty cultivated land, the data collected in this paper were screened by the method of 3 times standard deviation of mean, the characteristic values and conversion rates of the total element contents of seven available states, namely, alkali-hydrolyzed nitrogen, available phosphorus, available potassium, available Boron, available molybdenum, available zinc, and cation exchange capacity, were analyzed statistically, the abundance degree of available micronutrient in different land use types, soil parent rocks, soil types and towns was evaluated. It provides reference basis for land use adjustment, land use planning and fertilization in Anlong county. |
