通过不同生态区的小区试验 ,分析了叶面喷施氮肥对强筋小麦品种龙麦 2 6产量和品质的影响。研究结果表明 ,叶面喷肥的时期和次数对龙麦 2 6产量和品质影响不同 ,三叶期与开花期两次喷肥效果最好 ,三叶期一次喷肥不利于产量和品质提高。同一施氮肥处理对不同品质指标影响也不相同。最佳的叶面喷施氮肥处理对沉降值、最大抗延阻力、延伸性及面包体积有正向影响趋势 ,对蛋白质含量、稳定时间和面包评分影响不大
Through plot experiments in different ecoregions, the effects of nitrogen fertilizer on the yield and quality of strong gluten wheat variety Longmai 26 were analyzed. The results showed that the time and number of foliar spraying had different effects on the yield and quality of Longmai26, the best was the two-time spraying in the three-leaf stage and the flowering stage, and the one-time spraying in the three-leaf stage was not conducive to the yield and quality improvement. The same nitrogen fertilizer on the impact of different quality indicators are not the same. The optimum foliar application of nitrogen fertilizer has a positive effect on the sedimentation value, maximum resistance to resistance, elongation and bread volume, and has little effect on protein content, stability time and bread score
