Corresponding soil and water conservation tillage technology system processes was also proposed in this study to provide basic information that is needed to develop a soil and water conservation tillage system with Loess Plateau features.

In west area,the efficient farming technique can change slope landforms,reduce s.

The mechanized protective farming technique, which is a revolution of traditional agricultural tillage system, is an important measure for realizing agricultural sustainable development.

In 2003～2005,a research about the use of farming technology of fertilizer gathering and rainfall conservation was made to improve soil of arid maize in five areas of Lvliang City,at the same time,a comparison analysis is made among mechanical ridge-forming sowing with mulch,man-made ridge-forming planting,and common planting.

After a brief review of the achievements and problems of the two Green Revolutions and the reemerging traditionally organic agriculture, and forecasting the future precision farming technology, the auther analyses the political and economical backgrounds of the competitions of the existing farming technologies, and suggests some views on how China would catch the opp.

The high efficiency cultivation technique for upland farming is probed into the upland farming model and cultivation technique aspects.

This paper introduces some conservation tillage technology and countermeasures for these problems.

Based on the analysis of conservation tillage technology implementary significance,this paper analyses the procedure of its implementary benefit evaluation indicator system establishment,puts forward evaluation indicator system elementary design.

Taking Shanxi province as the example,this paper surveys and analyzes the situation and questions in extending conservation tillage technology.
