| 摘 要： | 根据自1984年以来的土壤监测数据,系统分析了20年来南海土壤地力变化趋势。结果表明,该区土壤存在酸化、有机质含量下降、钾素增加、磷素极大丰富的特点,据此提出推广平衡施肥技术和水旱轮作制度等利用、改良土壤和培肥地力的建议,以期为南海区耕地资源的保护、管理及合理利用提供参考。

| Abstract: | The change trend of soil degradation was analyzed in this paper in Nanhai District of Foshan.The results showed that the soils in this area investigated were prone to acidification.In contrast to inspection done before,contents of both organic matter and total N decreased,while K content increased,as well as P content dramatically enriched.Accordingly,some proposals for reasonably utilization and ameliorating the soils were also put forward,which made it possible to provide reference for protection and management of cropland resource in region of Nanhai. |
