摘要
[目的]获得苹果园化肥投入和土壤碱解氮、速效磷和速效钾的含量状况。[方法]对25个农户苹果园化肥投入进行调查,采集土壤样品进行测定分析。[结果]氮磷钾养分平均投入量为839.6、520.4、899.7 kg/hm2,氮磷钾养分的投入比为1.00∶0.62∶1.07。0~60 cm土壤碱解氮、速效磷、速效钾平均含量分别为53.49、70.73、180.10 mg/kg,土壤中碱解氮、速效磷、速效钾的比例为1.00∶1.32∶3.37。[结论]苹果园化肥投入总体水平比较高。土壤碱解氮的含量总体偏低,土壤速效磷的含量偏高,土壤速效钾的含量较高。
[Objective] The research aimed to get the formation about the content of alkaline hydaolytic nitrogen,available phosphorus,available potassium and the input rates of the chemical fertilizer in apple orchard.[Method] Based on 25 surveyed farmer in apple orchard,soil samples were collected and determined.[Result] The total input rates of NPK were 839.6、520.4、899.7 kg/hm2,respectively.N∶P2O5∶K2O was 1.00∶0.62∶1.07.The content of soil alkaline hydrolytic nitrogen,available phosphorous and available potassium were 53.49,70.73,180.10 mg/kg,respectively.The ratio of alkaline hydrolytic N,available P and available K was 1.00∶1.32∶3.37.[Conclusion] The total input rate of the chemical fertilizer were high.There were lower alkaline hydrolytic N,higher available P and available K in apple orchard.
