[目的]研究不同深度施磷对小麦生长、经济性状、产量及磷肥利用率的影响。[方法]对小麦根层不同深度施用磷肥,研究磷肥施用效应。[结果]0～5 cm施磷肥处理具有较好的增产效果,产量为4 500.00 kg/hm2,比不施磷增产42.8%,明显提高肥料利用率,比最小磷肥耕层施用利用率(15～20 cm)提高2.9个百分点。[结论]小麦施磷肥以0～5 cm施用效果最好。
[Objective] The research aimed to study the effects of phosphorus application on the growth, economic traits, yield and phosphorus use efficiency of wheat. [Method] The phosphate fertilizer was applied to wheat roots at different depths to study the effect of phosphate fertilizer application. [Result] Compared with no phosphorus application, the yield was 4 500.00 kg / hm2, and the yield of fertilizer was increased by 42.8% at 0 ~ 5 cm. The utilization rate of fertilizer was obviously higher than that of the minimum phosphorus fertilizer (15 ~ 20 cm) increased 2.9 percentage points. [Conclusion] The application of wheat phosphate fertilizer at 0 ~ 5 cm was the best.
