摘　　要：为了明确硅肥对春小麦生长发育及产量的影响,选用强筋春小麦品种龙麦26和中筋春小麦品种克旱16为试材,随机区组进行五个不同硅肥水平的田间试验。研究结果表明,施用硅肥可使小麦叶面积指数、茎部干重、叶片干重、地上部分总干物质积累显著提高,降低株高,增加茎粗和收获前有效穗数。而对千粒重的影响不大。其中龙麦26小穗数和穗粒数各处理与对照相比达极显著水平,而对克旱16小穗数和穗粒数的影响不大。施入硅肥可使两品种春小麦增产幅度达0.73%～14.7%。综上所述,生产上以施用硅肥量45 kg.hm-2为宜。The objectives of this study were to define the effect of silicon fertilizer on the growth and yield of spring wheat using the strong gluten spring wheat cultivars Longmai 26 and the medium gluten spring wheat cultivars Kehan 16 as experimental material by randomized block design of five different silicon fertilizer level field experiment. The results showed that applying silicon fertilizer could improve the leaf area index, the dry weight of stem and leaf, the ground part of the total dry matter accumulation of wheat significantly. And it also could reduce plant height and increase the stem diameter and panicles. But the influence of grain was not big. There were significant differences between treatments and CK in the number of spikelet and grain per panicle of Longmai 26, but there were no significant differences between treatments and CK in Kehan 16. Applying silicon fertilizer can increase 0.73%-14.7% yield of spring wheat . In conclusion,45 kg·hm-2 of silicon fertilizer was suitable in agriculture practice.
