摘要
2004年辽宁省土壤肥料总站在海城市采集土壤样品322个,对有机质、全氮、碱解氮、有效磷、速效钾、pH值、有效硫、有效镁、有效硅、有效钙、有效硼、有效钼、有效铁、有效锰、有效铜、有效锌等16项土壤养分指标进行了测试分析。结果表明,海城市土壤有机质含量较低,氮素和钾素含量不足,磷素含量丰富,中量元素除钙素外基本不缺,微量营养元素硼和钼缺乏,其他很丰富。菜田的土壤肥力较高,水稻田和果园次之,旱田土壤肥力最差。旱田和果园的碱解氮、水稻田的速效钾含量偏低。
In 2004,322 soil samples were collected by General Station of Soil and Fertilizer of Liaoning Province in Haicheng City.Sixteen soil properties,including;organic matter,total nitrogen,base hydrolysable nitrogen,available phosphorus, available potassium,pH,available sulfur,available magnesium,available silicon,available calcium,available boron,available molybdenum,available iron,available manganese,available copper,available zinc,were determined.The results showed that soil organic matter in Haicheng City was low;nitrogen and potassium were deficient,but phosphorus was abundance.Medium elements were not deficient except calcium,and microelements were abundance except boron and molybdenum.Content of hydrolysable nitrogen in dry land and garden was low,as well as available potassium in paddy soil.So from the soil fertility point of view,soil fertility was in the order of;vegetable soil〉paddy soil and garden soil〉dry land.
