| 摘 要： | [目的]为小麦高产栽培提供科学施肥理论依据。[方法]2012~2013年度,以小麦品种云麦53为材料,运用田间肥料裂区试验和分析方法研究了不同施肥方式对小麦产量、产量构成因素的影响。[结果]不同时期施氮肥能在0.01水平显著地提高籽粒产量,改善产量构成因素,并且效果优于施磷、钾肥及不施肥处理。[结论]小麦高产栽培的最优施肥方式是把16%过磷酸钙525 kg/hm2和50%硫酸钾225 kg/hm2全部作种肥一次性施入,46%尿素600 kg/hm2分不同时期施用,其中150 kg/hm2作种肥、225 kg/hm2作分蘖肥、225 kg/hm2作拔节肥。

| Abstract: | LObjectiveJ ＇Io provide a scientitic lertiDzatlon theoretical basis lor high y~eta cultivation ot wlaeat. LMettloO l Ltunng zutz-,：olJ,u- sing Yunmai53 as material,effects of different fertilization ways on wheat yield and yield components were studied by field fertilizer experiment and analysis method. [ Result ] Nitrogen application in different period can significantly improve grain yield and perfect yield components, the effect is better than phosphate fertilizer, potash fertilizer and no fertilizer treatment, [ Conclusion ] The optimum fertilizer application way for wheat high yield cultivation is 16% calcium superphosphate 525 kg/hmz and 50% potassium sulphate 225kg/hmz ,46% urea 600 kg/hm2, among which, 150 kg/hm2 as seed manure ,225 kg/hm2 as tillering fertilizer,225 kg/hm： as jointing fertilizer. |
