砀山县梨园土壤微量元素含量分析
Analysis on trace elements content in soil of pear orchard in Dangshan county
【摘要】 对砀山县黄河故道地区10个乡镇代表性梨园的土壤微量元素养分进行测试分析,结果表明:梨园土壤w(有效锌)为0.738~3.353 mg/kg,w(有效锰)为3.545~5.225 mg/kg,w(有效铁)为3.332~15.684 mg/kg,w(有效铜)为0.144~3.793 mg/kg,w(有效钼)为1.100~1.899 mg/kg,w(有效硼)为0.306~1.128 mg/kg。总体来看,土壤中有效锌和有效钼含量处于丰富或较丰富水平,有效锰和有效硼含量处于中等或较缺乏水平,有效铁和有效铜含量处于中等偏丰富水平。因此,应合理控施锌肥和钼肥,增施硼肥和锰肥。
【Abstract】 The trace elements content in soil of pear orchard in 10 villages and towns of the old Yellow River area in Dangshan county are tested and analyzed. The results show that the content of effective zinc ranges from0.738 mg/kg to 3.353 mg/kg, the content of effective manganese ranges from 3.545 mg/kg to 5.225 mg/kg, the content of effective iron ranges from 3.332 mg/kg to 15.684 mg/kg, and the content of effective copper ranges from 0.144 mg/kg to 3.793 mg/kg, the content of effective molybdenum ranges from 1.100 mg/kg to 1.899 mg/kg,and the content of effective boron ranges from 0.306 mg/kg to 1.128 mg/kg. In general, the contents of available zinc and available molybdenum in soil are at rich or relatively rich level, the contents of available manganese and available boron are at medium or lack level, and the contents of available iron and available copper are at medium to rich level. Therefore, the application of zinc and molybdenum fertilizers should be reasonably controlled, and the application of boron and manganese fertilizers should be increased.
