Abstract: There are broken topography,large slope land and severe soil erosion in the Loess Plateau.The investigations and experiments showed that taking various tillage technologies of soil and water conservation in line with the thought of suiting measures to local conditions, can change micro-landform of hillslope,decrease soil and water loss,increase anti-erosion and conserve water of soil,cultivate soil and improve crop yield on slope land apparently.This paper analyzed eight tillage technologies and their features of soil and water conservation.
