黑土区不同耕作措施的水土保持效益
Effects of different tillages on the soil and water conservation benefits in Northeast black soil area of China
摘要
Abstract
To find the effective methods for protecting the sloping farmland in Northeast black soil area from soil and water erosion,soil and water conservation benefit from sloping land with stubble,crop rotation and straw returning was analyzed by laboratory and field test in Tanzifang Watershed of Yitong County,Jilin Province.The results indicated that:1) Runoff and erosion were the highest in the control plot while plot with straw returning had the minimum value.Compared with the control,runoff and soil erosion of plots with different tillage measures were decreased by 36.4％-66.7％ and 75.2％-86.4％ respectively.2) Compared with the control,soil organic matter content in the sediment under stubble,crop rotation and straw returning measures was reduced by 56.6％,62.8％ and 81.4％,the content of total nitrogen by 53.3％,60.0％ and 80.0％ and total phosphorus content by 38.5％,61.5％ and 84.6％,respectively.Moreover,soil nutrient loss with different tillages decreased by more than 85％ compared with the control.关键词
