In order to explore the effects of different types of potassium fertilizer on mixograph parameters of strong gluten wheat, the high-quality strong-gluten wheat variety Longmai 26 was used as the test material, and potassium sulfate and potassium chloride were used as the tested potassium fertilizers. Four treatments were set up as 0, 22.5,37.5, 52.5 kg/ha. The results showed that different application amounts of potassium fertilizer had an effect on the mixing parameters, but the differences were not significant. So it was suggested that 22.5 kg/ha fertilizer amount treatment was suitable for mix time and peak integral of tail; 37.5 kg/ha fertilizer amount treatment was suitable for peak width; 52.5 kg/ha fertilizer amount treatment was suitable for peak value, eight-minute height and eightminute width. Applying potassium chloride was beneficial for the expression of dough mix time, peak value, peak width, integral of tail and eight-minute height, while applying potassium sulfate was only beneficial for eightminute bandwidth. The application effect of potassium chloride was better than that of potassium sulfate. Therefore,in the plot with good soil fertility, the application of potassium chloride was suitable for the production of strong gluten wheat, which can not only reduce the production costs but also improve the quality and efficiency.
