本文研究了小麦在华南地区浅圆仓储存过程中品质特性的变化。研究结果表明：随着储藏时间的延长，小麦水分、面筋含量、面筋吸水量和发芽率均呈下降趋势；而小麦降落数值、面团形成时间、拉伸面积、拉伸阻力及最大拉伸阻力、拉伸比例及最大拉伸比例均呈上升趋势，说明在长期的储存过程中小麦的品质发生了一定的变化。高温高湿的华南地区浅圆仓储存小麦安全储藏水分为12.5%，浅圆仓常规储存安全水分小麦，轮换周期可以适当延长至4~5年。

The changes of quality properties of wheat during storage in large squat silo of South China were investigated in the present study. Results showed that moisture content, wet gluten content, gluten absorption ratio and germination rate of wheat with different varieties decreased gradually, while falling number, forming time of dough, extension area, extension resistance, maximum extension resistance, extension ration and maximum extension ration increased gradually with the extension of storage time. All these results indicated that quality properties of wheat during storage in large squat silo of South China deteriorated to some extent. Results from this study also suggested that the safe moisture content of wheat in South China could be set as 12.5%, and transition period of wheat with safe moisture content stored in large squat silo could be extent to 4~5 years.
