研究聚磷酸铵的施用对土壤有效锌、锰和植株体内锌、锰累积量及作物农艺性状的影响。结果表明,与对照相比,施用聚磷酸铵的土壤中有效态锌、锰含量增加1.5倍左右,随着时间的推移,呈现上升至最高点下降并趋于稳定的趋势。施用聚磷酸铵使小白菜、黄瓜和玉米植株体内锌、锰的累积量提高5.97%～23.47%,w(叶绿素)提高12.07%～20.97%,茎粗提高3.90%～16.57%。
Abstract：The effects of APP on availability of Mn and Zn in soil, the accumulation of Mn,Zn in plant and the agronomic traits of plant are studied. The results show that, compared with control, the application of APP can increase the content of active Mn and Zn in the soil by 1.5 times, which first rises and then falls to a stable state,and the accumulation of Mn, Zn in plant increases by 5.97%-23.47%, SPAD increases by 12.07%-20.97%, stem thickness increases by 3.90%-16.57%.
