The results showed that the Sodium sulfate removal rate is higher and nutrient loss is least and submergedvegetation is not almost broke while the moisture is 45%.
试验结果表明：在含水率为45%时进行碾压，硫酸钠的去除率较高，营养物质损失最少，水草基本不破碎。

By the indoor flume model experiment, the changing law of vertical velocity distribution and turbulent intensity of submergedvegetation channel linings are discussed.
So from the feature and manufacturing technology of submergedvegetation, 45% is the best moisture while removing Sodium sulfate on the process of drying submergedvegetation.
