| 摘 要： | 通过对运城市盐湖区农田耕层(0～20cm)土壤样品的分析,结果表明:2003年与1990年相比较,全区农田耕层土壤的有机质、全氮、有效磷、速效钾含量均呈上升趋势,且时空分布基本一致,但在丰缺指标中,有机质、全氮仍处于低水平。因此,在生产中应通过增施有机肥、巧施氮肥来增加有机质、全氮的含量,从而保证土壤养分平衡,使农作物达到高产稳产优质的目的。 |

| Abstract: | The analysis of soil sample of farmland plough layer(0～20cm) in Yanhu District of Yuncheng City shows that: compared with 1990,it presents the uptrend of the content of organic matter,nitrogen,available phosphorus and potassium in 2003,but considering the depth index,the content of organic matter and nitrogen is at low level.Therefore,in actual production,we should increase the content of organic matter and nitrogen by increasing organic fertilizer in order to ensure soil nutrient balance,high yield and high quality. |
| Keywords: | farmland plough layer soil nutrient countermeasures |
