摘　　要：低聚合度聚磷酸铵是一种高效缓释水溶性磷肥,为了研究聚磷酸铵在土壤中有效性的影响因素和磷素转移规律,利用内蒙古、新疆、贵州、陕西渭南和陕西榆林共五种不同土壤,分别加入等量的低聚合度聚磷酸铵,通过土柱淋洗的方法研究聚磷酸铵在不同土壤中磷素转移规律,为低聚合度聚磷酸铵在农业领域的推广和使用提供技术支持.Ammonium polyphosphate with low degree of polymerization is a high-efficiency slow-release water-soluble phosphate fertilizer.In order to study the factors affecting the availability of ammonium polyphosphate in soil and the law of phosphorus transfer,we selected five different soils in Inner Mongolia,Xinjiang,Guizhou,Weinan,Shaanxi,and Yulin(Shaanxi province)as test soils.The same amount of ammonium polyphosphate with low polymerization degree was added respectively,and the phosphorus transfer law of ammonium polyphosphate in different soils was studied by the method of soil column leaching.This study provides technical support for the promotion and use of ammonium polyphosphate with low polymerization degree in the agricultural field.
