摘　　要：为掌握重庆市铜区梁农田土壤肥力状况,更加科学地指导农业生产,文章选择铜梁具有代表性农田进行土壤养分采集与分析。结果表明:该区域不同农田土壤养分差异极显著(P<0.01),土壤大多属于中性土壤,适宜作物生长,但有机质、氨解氮、有效磷含量普遍较缺乏,速效钾含量丰富,因此,在施肥中应多施氮和磷肥。In order to better grasp the soil fertility of Tongliang farmland and guide agricultural production more scientifically,this study selected the representative farmland of Tongliang to collect and analyze soil nutrients.The results showed that there were sig‐nificant differences in soil nutrients among different croplands(P<0.01)in this area.Most of the soils were neutral soil,which was suitable for crop growth,but the contents of organic matter,ammonia-hydrolytic nitrogen and available phosphorus were generally short,and the content of available potassium was rich.Therefore,more nitrogen and phosphorus should be applied in fertilization.
