- Abstract:
-
Using simulated rainfall, we investigate how the corn stalk juice impacts the sediment yield rate on loess slop. Four treatments of corn-stalk-juice-treated soil and four rainfall intensities are designed to study the sediment yield rate. The soil treatments include a control group, corn-stalk-juice-treated groups with 25% concentration and 50% concentration, and a group treated by corn juice with 25% concentration and freeze thaw control. The rainfall intensities are set as 25 mm/h, 50 mm/h, 75 mm/h, 100 mm/h. The relationship among soil aggregates, organic matter and sediment yield rate was analyzed for the four soil treatments. The results indicated that: (1) the corn stalk juice could remarkably reduce the sediment yield rate via increasing the >0.25 mm aggregates and organic matter; (2) there is a significantly linear correlation between the >0.5 mm aggregates and organic matter in the four soil treatments; there is a significantly negative linear correlation between sediment yield rate and >0.25 mm soil aggregates as well as organic matter.
