描述： teau the seeding season is cold and little rainfall. Soil temperature,moisture and fertilizer is an important factor in crop yield. So in this area dissemination conservation tillage of importance. Most of former researches in comparison between conservation tillage and conventional tillage. This experimentation compare with sereval conservation tillage's difference. Through this comparison, wind-water erosion in the Loess Plateau ecologically fragile areas and application of a reasonable choice of different measures to provide a reference of farming with a view to achieving the sustainable and health development of agriculture. In this study, selection of test sites in the Loess Plateau in northern China typical wind-water erosion area Shenmu, a no-tillage, straw mulch, plastic film mulching, mulching ridge, ridge of the five kinds of different measures of conservation tillage experiment, observe ground temperature,soil nutrients,soil moisture,yeild and soil and water loss.
