- Abstract:
-
By the basis of experiments of simulated rainfall, the effects of different quantity straw mulch on runoff water infiltration and soil erosion are studied.The results show that straw mulch increase water infiltration, reduce runoff and soil erosion.The cover rate more than 40% control water and soil loss, ortherwise the contrary result.Under water content 10% and 120 mm/h rainfall rate, straw mulch delay runoff 1~15 minutes, increase accumulative infiltration 37%~113%, reduce runoff 3%~40%, and soil erosion 10%~80%.Effects of straw mulch control soil and water loss increase as cover rate increases.
