| 摘 要： | 为了解城市郊区土壤养分状况,制定科学的施肥管理措施,对新乡市郊区1 500个土壤样品养分进行了抽样化验分析。结果表明,新乡市郊区土壤养分平均含量为:有机质34.61g/kg、全氮2.08g/kg、有效磷21.95 mg/kg、速效钾211.69 mg/kg,均属于高水平,但分布不均衡,其中,28.55%地块磷素含量偏低。同时,根据土壤肥力现状,提出了秸秆还田、稳氮、增磷、控钾、补微的施肥指导方针及相应的施肥对策。 |

| Abstract: | In order to understand the soil nutrient status in city suburbs and work out scientific production measures,1 500 soil samples from Xinxiang city suburb were selected to analyze the conditions of soil nutrients.The results showed that the soil nutrient was mainly constituted by 34.61 g/kg of organic matter,2.08 g/kg of total nitrogen,21.95 mg/kg of effective phosphorus,and 211.69 mg/kg of available potassium on average.All the nutrient components listed above are at a high level,but unevenly distributed.For instance,28.55% of farmlands possess low phosphorus content.According to the soil nutrient status,fertilization guidelines,such as the straw returned,nitrogen stabilized,phosphorus increased,potassium controlled,and microelement fertilizers supplemented,and the corresponding countermeasures are put forward. |
