【摘要】 为探究不同类型钾肥对强筋小麦品质的影响，以优质强筋小麦品种龙麦26为试材，进行两种类型钾肥的对比试验。设置4个处理水平，分别为0、22.5、37.5、52.5 kg/hm~2。结果表明，硫酸钾在不同处理水平下，各主要品质指标均表现差异不显著；氯化钾在不同处理水平下，籽粒蛋白、沉降值、面筋指数、吸水率、稳定时间等品质指标表现差异不显著，拉伸面积和最大拉伸阻力则表现差异显著。两种钾肥的最佳施用量均为37.5 kg/hm~2。在土壤肥力较好且有机质含量丰富的地块，施用氯化钾比硫酸钾更适用于强筋小麦生产，这样既达到了降低生产成本又起到了提质增效的目的。更多还原

【Abstract】 To explore the effect of different types of potassium fertilizer on quality of strong gluten wheat, with strong gluten wheat variety Longmai 26 as tested materials, the contrast test was conducted on two different types of potassium fertilizer. Four treatments were set up: 0, 22.5, 37.5, 52.5 kg/ha. The results showed that: There was not significant differences in the main quality indexes in different potassium sulfate treatments. In different potassium chloride treatments, grain protein, sedimentation value, gluten index, water absorption and stability time were not significant differences, tensile area and maximum tensile resistance were significant difference. The best application amount of two different types of potassium fertilizer is 37.5 kg/ha. In the plot with good soil fertility and rich organic matter, potassium chloride is more suitable for the production of strong gluten wheat than potassium sulfate, which not only reduces the production cost but also improves the quality and efficiency.更多还原
