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

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.
