摘要
[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 phosphate fertilizer applied in deep place of root layer on wheat growth,yield,economic characters,and the utilization rate of phosphate fertilizer.[Method] Phosphate fertilizer was applied on wheat root layer with different depth,and the effects of fertilizer application were studied.[Result] 0-5 cm fertilizer treatment had better effect on increasing yield,and the yield was 4 500 kg/hm2 increased by 42.8％ compared CK.The treatment could improve the utilization rate of fertilizer,increased by 2.9 percentage point compared with that of minimal phosphate fertilizer application in 15-20 cm.[Conclusion] The best effect of the phosphate application was 0-5 cm layer.
