| 为了对贵阳市花溪区土壤养分状况进行评价，基于土壤养分元素的测试分析数据，利用Microsoft Excel2010软件对数据进行统计、处理，并对土壤养分中的上述指标进行概括性分析，结果表明:贵阳市花溪区耕地土壤以酸性为主；有机质含量以中等等级以上为主；大量元素氮、磷、钾中除钾元素含量处于较缺乏状态外，其他均为中等等级以上；微量元素(硼、锰、锌)含量均以中等等级以上为主；养分元素主要集中在碳酸盐岩类成土母岩、茶园、林地及水田，黄壤、黄棕壤中；土壤养分含量较高区主要分布在湖潮、石板、党武、青岩、高坡等乡镇。对此，提出调节土壤酸碱度、将有机肥与氮、磷、钾肥料有机结合、重视微量元素的使用、推广测土配方施肥技术等建议。 |

| In order to evaluate the status of soil nutrients in Huaxi District of Guiyang city, Based on the test and analysis data of soil nutrient elements, Microsoft excel 2010 software was used to conduct statistics and processing on the data, and the above indicators in soil nutrients were analyzed generally, The results show that: In Huaxi District of Guiyang City, the soil is mainly acidic; the content of organic matter is mainly above medium grade, the contents of nitrogen, phosphorus and potassium are all above medium level except potassium; the contents of trace elements (boron, manganese and zinc) are mainly above medium grade. The nutrient elements are mainly concentrated in carbonate rock, tea garden, forest land and paddy field, yellow soil and yellow brown soil, the areas with high soil nutrient content are mainly distributed in Huchao, Shiban, Dangwu, Qingyan, Gaopo and other towns. Therefore, some suggestions are put forward, such as adjusting soil pH, combining organic fertilizer with nitrogen, phosphorus and potassium fertilizer, paying attention to the use of trace elements, and popularizing soil testing and formula fertilization technology. |
