摘  要:
对山东寿光南部4个乡镇19个自然村大棚耕层土壤养分及金属元素含量进行了调查,以期为大棚土壤科学施肥提供依据。结果表明:耕层土壤养分总体含量很丰富,土壤平均pH6.25,平均C/N为13.96,全氮平均含量为3.12g·kg~(-1),有机质含量很丰富,平均值为41.25g·kg~(-1),有效磷、速效钾含量很丰富,平均值分别为1 492.1、776.6mg·kg~(-1);土壤中金属元素有效钙、镁、铁、锌、铜、锰含量均极为丰富,平均值分别为6 007、1 053、178.29、91.77、11.35、221.8mg·kg~(-1)。因此,在实践中应当控制并减少施肥量,确保环境安全。

摘  要:
Investigation of the topsoil nutrients and metal elements in greenhouse soils was conducted in four towns of Shouguang,Shandong Province,in order to provide scientific fertilization for greenhouse soils.The results showed that the top soil nutrients and metal elements in the tested area were rich,while the average contents of pH,C/N,organic matter,total N,available P,K,Ca,Mg,Fe,Zn,Cu and Mn were 6.25,13.96,3.12 g· kg~(-1),41.25 g· kg~(-1),1 492.1mg·kg~(-1),776.6mg·kg~(-1),6 007 mg·kg~(-1),1 053 mg·kg~(-1),178.29 mg·kg~(-1),91.77 mg·kg~(-1),11.35mg·kg~(-1),221.8mg·kg~(-1).Meanwhile,the quantity of fertilization should reduce properly to insure environment safety in practice.
