| 摘 要： | 华北北部沙质潮土区冬小麦产量较低,为摸清区域内冬小麦养分吸收规律,提高施肥效率,通过田间试验研究了区域内冬小麦养分吸收动态及不同肥料因子对产量的影响,结果表明:该区域冬小麦养分吸收速率最快时期出现在拔节期至抽穗期,生育后期的养分吸收比例相对较低;氮磷钾配合施用不仅可以提高冬小麦的养分吸收量,还可以促进养分向子粒中运转;增加冬小麦有效穗数及调节产量构成因素间的平衡关系,是提高产量的有效田间管理措施;控制养分投入数量,调整养分投入比例,保持养分持续供应强度,增强土壤对养分投入的缓冲能力是提高产量的有效施肥技术。

| Abstract: | The yield of winter wheat is lower on sandy Fluvo-aquic in the northern area of the North China.An experiment was set up to study characteristics of fertilizer requirement and fertilization technology of winter wheat in this area.The results indicated that the peak of nutrient absorption velocity was showed between jointing stage and heading stage.The nutrient absorption proportion during later development period was lower than others reports.Balanced fertilization was the key factor which influenced the am... |
