摘要
以2013年陕西省韩城市农业土壤为研究对象,并与1982年的土壤养分进行对比,再利用Excel软件对数据进行统计和处理。结果表明,该区农业土壤主要是碱性土,有机质、全氮和碱解氮都位于适量状态,而有效磷位于缺乏状态,速效钾达到非常丰富的状态。与1982年比较,2013年韩城市农业土壤中各养分含量都有大范围提高。
Taking agricultural soil of Hancheng City in Shaanxi Province in 2013 as the research object,compared with the soil nutrients in 1982,and then used the Excel software to analyze the data.Resuhs showed that the agricultural soil in this area was mainly alkaline soil.Organic matter, total nitrogen and alkali hydrolyzed nitrogen all reached the appropriate level,but the available phosphorus was lack, available potassium achieved an extremely rich level. Compared with 1982, organic matter, total nitrogen, alkali solution nitrogen, available phosphorus, available potassium content of agricultural soil in Hancheng City in 2013 had a significant increase.
