Abstract

Abstract:

【Objective】 To study the effects of different phosphorus application methods on the growth of drip irrigation wheat and the utilization rate of phosphorus fertilizer in order to provide reference for the efficient utilization of phosphorus fertilizer in drip irrigation wheat.【Methods】 Under the condition of field drip irrigation, winter wheat Xindong 41 was used as the experimental material. Under the condition of equal amount of nitrogen, phosphorus and potassium, six phosphorus fertilizer application methods were set: F₀: no phosphorus application, F₁:100% basic application, F₂:75% basic application + 25% topdressing, F₃:50% basic application + 50% topdressing, F₄:25% basic application + 75% topdressing and F₅:100% topdressing to study the effects of different phosphorus application methods on dry matter, nutrient accumulation, yield and phosphorus fertilizer utilization rate of wheat. 【Results】 Phosphorus application significantly increased the dry matter and nutrient accumulation of wheat and increased the yield. Phosphorus application treatment increased the number of ears, grains per ear and 1,000-grain weight. The number of ears, grains per ear and 1,000-grain weight of phosphorus application treatment increased by 5.93%-23.99%, 0.32%-8.76% and 1.78%-6.45% respectively compared with F₀ treatment. There were differences in wheat yield and components under different phosphorus application treatments. The number of panicles, grains per panicle and 1,000 grain weight of F₃ treatment were the best. The yield of F₃ treatment was 10.21% higher than that of F₅ treatment, and the difference was significant. The phosphorus fertilizer utilization rate, partial productivity and agronomic efficiency of F₃ treatment increased by 11.00%, 4.81 kg/kg and 4.80 kg/kg respectively compared with F₁ treatment. 【Conclusion】 F₃ treatment (50% basal application + 50% topdressing) has the best performance in population yield components and reaches high fertilizer utilization rate.

Key words: wheat; phosphorus application method; growth; utilization rate of phosphate fertilizer

摘要：

【目的】 研究不同施磷方式对滴灌小麦生长和磷肥利用率的影响,为滴灌小麦磷肥的高效利用提供参考。【方法】 在大田滴灌条件下,以冬小麦品种新冬41号为材料,在等量养分条件下,设置6个磷肥施用方式,F₀:不施磷、F₁:100%基施、F₂:75%基施+25%追施、F₃:50%基施+50%追施、F₄:25%基施+75%追施、F₅:100%追施,分析不同施磷方式对滴灌小麦干物质及养分积累量、产量和磷肥利用率的影响。【结果】 施磷显著增加了小麦的干物质、养分积累量,施磷处理提高了穗数、穗粒数、千粒重,施磷处理的穗数、穗粒数、千粒重分别比F₀处理增加5.93%~23.99%、0.32%~8.76%、1.78%~6.45%,施磷显著提高了产量。不同施磷方式下小麦产量和构成因素存在差异。穗数、穗粒数、千粒重均以F₃处理表现最好,F₃处理产量比F₅处理增加10.21%,且差异显著。F₃处理干物质积累量和养分积累量表现最好。F₃处理的磷肥利用率、磷肥偏生产力、磷肥农学效率比F₁处理分别增加11.00%、4.81 kg/kg、4.80 kg/kg。【结论】 F₃处理(50%基施+50%追施)群体产量构成因素表现最好,具有较高的养分积累量和肥料利用率,利于磷肥的高效利用。
