摘  要：
【目的】研究施用不同防磷固定剂对磷在土壤中移动深度及持续有效性的影响,以提高磷肥利用率,满足作物对磷素的需求。【方法】采用连续浸提法、室内模拟土柱法,研究不同防固定剂(A,B,C)对水溶性磷肥(MAP)在土壤中移动的有效深度的影响。【结果】在滴灌条件下,滴施常量水溶性磷肥在土壤中很快被固定而无效,增加了施肥成本。防磷固定剂可提高水溶性磷在土壤中的移动深度,迁移至10 cm以下,但不超过15 cm。150 d内施用防磷固定剂可持续增加土壤的速效磷含量,净增量是水溶性磷肥的0.88~1.29倍。【结论】防磷固定剂A,B,C能防止水溶性磷肥被土壤固定,增加P素在土壤中的移动性。

摘  要：
【Objective】The effects of different phosphorus fixing agent on promoting P mobility and availability were studied in order to improve phosphorus fertilizer utilization efficiency and meet the demand for P in crops.【Method】Taking anti-fixative phosphorus A,B,C as test materials and using indoor simulated drip irrigation and continuous water extraction experiment design,the effects of anti-fixative phosphorus( A,B,C) and monoammonium phosphate( MAP) on the mobility of phosphorus in soil were explored.【Result】Under the condition of drip irrigation,the constant water soluble phosphate fertilizer was fixed and ineffective in the soil,which increased the cost of fertilizer application. At the same flow rate of dripping,phosphorus moved longer vertical distance at higher phosphorus concentrations,and available phosphorus moved vertically 15 cm( Leaks were not detected). The available phosphorus content of the soil was increased by the application of anti-fixative phosphorus in 150 days,and compared to water soluble phosphorus,the net increase of phosphorous of anti-fixative phosphorus were 0. 88-1. 29 times.【Conclusion】The anti-fixative phosphorus A,B and C can prevent water soluble phosphorus from being fixed in soil,and can increase the distance of P movement.
