| Abstract: | The technique of conservation tillage is one of the most advanced agricultural techniques in the world. It could decrease flow on surface of fields,protect soil from water and wind erosion,increase organic matter content in soil,improve physical and chemical character and fertility of soil,which contained methods of free and little tillage and cover of field with remaining stubble. It was also the linchpin way to realize sustainable development of arid farming,which could keep soil,water,fertilizer in field... |
