| 摘 要： | 为了探讨弱筋小麦产量和品质同步提高的氮、磷肥最佳投入模式,选取弱筋品种郑麦004为试验材料,在弱筋麦适宜区信阳、罗山、息县三地进行了氮、磷肥施用模式试验。结果表明,随着施氮量的增加和追施氮肥时间的推迟,弱筋小麦产量和湿面筋含量有所增加,因此应"稳底控追",保证产量,稳定品质;增施磷肥和后期喷洒磷酸二氢钾均能提高弱筋小麦产量,但对品质指标影响较小。因此提出了"氮肥可‘稳底控追’、磷肥可‘增底补喷’"的弱筋麦高产优质氮磷运筹模式。通过优化氮磷肥配施模式,从而优化了弱筋麦的主要品质指标。

| Abstract: | With the weak gluten wheat variety,Zhengmai 004 as the test material,the best application mode of nitrogenous and phosphorus fertilizer leading to yield and quality synchronization improvement of weak gluten wheat was investigated in Xinyang,Luoshan and Xixian,the suitable areas for weak gluten wheat.The results showed that the yield and wet gluten content were increased with the increase of nitrogen and delay of top-dressing.Increase of phosphorous fertilizer or addition of potassium dihydrogen phosphate at late period resulted in increase of grain yield,but little effect on the quality indicators.By optimizing nitrogenous and phosphorous fertilizer application mode,the main quality indicators of weak gluten wheat were optimized.In order to improve the yield and quality,basal N fertilizer should be stabilized with controlled top-dressing and basal P fertilizer should be increased with spraying. |
