Effects of Conservation Tillage on Soil and Water Loss from Sloping Farmland in Heibeishan Watershed
摘要
Abstract
Through runoff plot experiment on slope,runoff,erosion and nutrient loss in Heibeishan watershed from May to August in 2009 and 2010 were studied.Results indicated that runoff,erosion,and nutrient loss from runoff plots under natural rainfall condition had a certain similarity.They were in the decreasing order of bare land,ridged-furrow,contour listing,film mulching,and equal-height deep loosening.Compared with the bare area,the conservation tillage could reduce runoff by 29.8%~63.3%,soil erosion by 64.6%~96.6%,nitrogen loss by 54.0%~89.5%,and total phosphorus loss by 49.4%~92.2%.This suggests that conservation tillage can play very good roles in conserving soil and water and reducing nutrient loss.关键词
