摘要:

【目的】探究不同磷肥对土壤磷素形态转化及小麦磷素吸收利用效率的影响,为土壤-磷肥-作物体系磷肥精准匹配及高效利用提供理论依据。【方法】在砂姜黑土和红壤上设置不施磷(CK)、施用过磷酸钙(SSP)、钙镁磷肥(FMP)、磷酸二铵(DAP)、重过磷酸钙(TSP)和聚磷酸铵(APP)6个处理,研究小麦拔节期和开花期根际与非根际土壤中磷库转化特征及其与植株体内磷素累积利用的关系。【结果】砂姜黑土施用磷肥后土壤有效磷含量提高194%—662%,不同磷肥处理小麦根际土壤中有效磷含量为APP>TSP>DAP>FMP>SSP>CK处理。施用磷肥显著提升了小麦拔节期和开花期砂姜黑土中H2O-P和NaHCO3-Pi含量,降低Residual-P含量,其中H2O-P和NaHCO3-Pi含量与土壤有效磷含量呈显著正相关,TSP和APP处理在小麦拔节期对NaHCO3-Pi含量提升幅度最大,分别较不施磷提升了41.0和36.0 mg·kg-1。红壤施用磷肥后根际土壤有效磷含量提高84%—791%,其中DAP和TSP处理的土壤有效磷含量显著高于其他磷肥处理,红壤中根际土壤NaHCO3-Pi和NaOH-Pi含量与土壤有效磷含量呈显著正相关,施用磷肥后红壤中NaHCO3-Pi和NaOH-Pi含量分别提高275.2%—848.3%和26.9%—58.3%,其中DAP和TSP处理提升效果最为显著。砂姜黑土和红壤上小麦植株磷素累积量与土壤有效磷含量在小麦拔节期均呈现显著正相关关系,砂姜黑土和红壤小麦植株磷素累积量与土壤有效磷含量在小麦拔节期均呈现显著正相关关系,根际土壤有效磷含量每提高1 mg·kg-1,小麦植株磷素累积量分别提高0.87和0.37 mg/pot。砂姜黑土施用不同磷肥均可显著提高植株磷素累积量,较不施磷提高15.4%—50.9%,其中APP和TSP处理使小麦植株磷素累积量及磷素利用效率较其他磷肥处理显著提高。红壤中施用不同磷肥使磷素累积量和产量分别较不施磷提高123.7%—643.9%和75.5%—337.2%,其中TSP处理的小麦产量、植株磷素累积量和磷素吸收效率较其他磷肥处理均显著提高。【结论】砂姜黑土施用重过磷酸钙和聚磷酸铵显著提高土壤H2O-P和NaHCO3-Pi含量,红壤施用重过磷酸钙和磷酸二铵可显著提高土壤NaHCO3-Pi和NaOH-Pi含量。因此,从提高磷肥利用效率角度考虑,两种土壤均适合施用重过磷酸钙,种植小麦时,砂姜黑土还可推荐施用聚磷酸铵,红壤可选用磷酸二铵。

Abstract:

【Objective】 Effects of different phosphorus (P) fertilizers application on soil P transformation as well as P uptake and utilization in wheat were investigated, so as to provide a theoretical basis for precise matching and efficient utilization of P fertilizer in soil - P fertilizer - crop system. 【Method】 The pot experiment was conducted in lime concretion black soil and red soil including six treatments: no P fertilizer (CK); application of calcium superphosphate (SSP), calcium magnesium phosphate (FMP), diammonium phosphate (DAP), calcium superphosphate (TSP) and ammonium polyphosphate (APP). The relationship between the P transformation in rhizosphere as well as non-rhizosphere soils with P accumulation in wheat at the jointing and anthesis stages was analyzed. 【Result】 Soil Olsen-P concentration increased by 194%-662% after application of P fertilizer in lime concretion black soil. Soil Olsen-P concentration in wheat rhizosphere soil followed the order: APP, TSP, DAP, FMP, SSP, and CK. The H2O-P and NaHCO3-Pi concentration was significantly increased, whereas the Residual-P concentration was significantly reduced after phosphate fertilizer application. Both H2O-P and NaHCO3-Pi concentration was positively correlated with soil Olsen-P. At the jointing stage, in comparison to that of the control, TSP and APP application increased NaHCO3-Pi concentration by 41.0 and 36.0 mg·kg-1, respectively. For the red soil, soil Olsen-P concentration in rhizosphere soil increased by 84%-791% as P fertilizer was applied. And soil Olsen-P concentration under DAP and TSP treatments was significantly higher than that under other P fertilizer treatments. The NaHCO3-Pi and NaOH-Pi concentration increased by 275.2%-848.3% and 26.9%-58.3%, respectively, which was positively correlated with rhizosphere soil Olsen-P concentration. After P fertilizer application, the most significant effects were found under DAP and TSP treatments. At the jointing stage, there was a significant positive correlation between shoot P accumulation and soil Olsen-P concentration in lime concretion black soil and red soil. When soil Olsen-P concentration increased by 1 mg·kg-1, shoot P accumulation increased by 0.87 and 0.37 mg/pot respectively in lime concretion black soil and red soil. In lime concretion black soil, shoot P accumulation significantly increased by 15.44%-50.9% compared with the control as different P fertilizers addition, and the APP and TSP significantly increased shoot P accumulation and utilization efficiency in shoot than other P fertilizers. After P fertilizer application in red soil, shoot P accumulation and grain yield of wheat increased by 123.7%-643.9% and 75.5%-337.2%, respectively. The grain yield, shoot P accumulation and P utilization efficiency under TSP treatments were significantly higher than that under other P fertilizer treatments. 【Conclusion】 In lime concretion black soil, the concentration of H2O-P and NaHCO3-Pi was significantly increased after application of APP and TSP. In red soil, the NaHCO3-Pi and NaOH-Pi concentration was significantly increased after the application of DAP and TSP. Therefore, in order to increase wheat P efficiency, APP or DAP was recommended as a proper fertilizer in lime concretion black soil, while DAP or TSP was recommended as a proper P fertilizer in red soil.
