| 摘 要： | 为了解土地整理新增耕地土壤物质组成及土壤肥力状况,对新增耕地土壤矿物成分、化学成分、污染元素和土壤化学性质进行了分析,分析结果将为新增耕地土壤培肥提供依据.实验结果表明新增耕地土壤养分的有效氮、磷、钾及有机质比较缺乏,必须对其进行培肥.利用固体废物对新增耕地土壤进行培肥,其成本低,工艺简单,培肥效果良好.

| Abstract: | To understand the soil components of added cultivated land and its fertility in land consolidation, minerals, chemical components and their properties and pollutants of the land were analyzed. The results can be the basis of soil fertility improvement.The results show that the added lands are lack of available nitrogen, phosphorus, potassium and organic matter. It is necessary to improve the soil fertility. Solid wastes with lower cost are used to improve the soil fertility. The technique of the fertility improvement is simple and efficient. |
